Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian host is missing a security update. It is, therefore, affected by multiple vulnerabilities in MediaWiki :

- A cross-site scripting (XSS) vulnerability exists due to a failure to validate input before returning it to the user. An unauthenticated, remote attacker can exploit this, via specially crafted SVG files, to execute arbitrary script code in the user's browser session. (CVE-2013-2031)

- A flaw exists in the password blocking mechanism due to two different tools being used to block password change requests, these being Special:PasswordReset and Special:ChangePassword, either of which may be bypassed by the method the other prevents. A remote attacker can exploit this issue to change passwords. (CVE-2013-2032)

- Multiple flaws exist in Sanitizer::checkCss due to the improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit these to bypass the blacklist. (CVE-2013-4567, CVE-2013-4568)

- A flaw exists due to multiple users being granted the same session ID within HTTP headers. A remote attacker can exploit this to authenticate as another random user. (CVE-2013-4572)

- A cross-site scripting (XSS) vulnerability exists in the /includes/libs/XmlTypeCheck.php script due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted XSL file, to execute arbitrary script code in the user's browser session. (CVE-2013-6452)

- A flaw exists in the /includes/upload/UploadBase.php script due to a failure to apply SVG sanitization when XML files are read as invalid. An unauthenticated, remote attacker can exploit this to upload non-sanitized XML files, resulting in an unspecified impact. (CVE-2013-6453)

- A stored cross-site (XSS) scripting vulnerability exists in the /includes/Sanitizer.php script due to a failure to properly validate the '-o-link' attribute before returning it to users. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in the user's browser session. (CVE-2013-6454)

- A flaw exists in the log API within the /includes/api/ApiQueryLogEvents.php script that allows an unauthenticated, remote attacker to disclose potentially sensitive information regarding deleted pages. (CVE-2013-6472)

- Multiple flaws exist in the PdfHandler_body.php, DjVu.php, Bitmap.php, and ImageHandler.php scripts when DjVu or PDF file upload support is enabled due to improper sanitization of user-supplied input. An authenticated, remote attacker can exploit these, via the use of shell metacharacters, to execute execute arbitrary shell commands. (CVE-2014-1610)

- A cross-site request forgery (XSRF) vulnerability exists in the includes/specials/SpecialChangePassword.php script due to a failure to properly handle a correctly authenticated but unintended login attempt. An unauthenticated, remote attacker, by convincing a user to follow a specially crafted link, can exploit this to reset the user's password. (CVE-2014-2665)

Solution

Upgrade the mediawiki packages. For the stable distribution (wheezy), these issues have been fixed in version 1:1.19.14+dfsg-0+deb7u1 of the mediawiki package and version 3.5~deb7u1 of the mediawiki-extensions package.

Public Exploits

Target Network Port(s): N/A
Target Asset(s): N/A
Exploit Available: True (Metasploit Framework, Exploit-DB, Core Impact, D2 Elliot)
Exploit Ease: Exploits are available

Here's the list of publicly known exploits and PoCs for verifying the Debian DSA-2891-1 : mediawiki, mediawiki-extensions Multiple Vulnerabilities vulnerability:

Metasploit: exploit/multi/http/mediawiki_thumb
[MediaWiki Thumb.php Remote Command Execution]
Exploit-DB: exploits/multiple/remote/31767.rb
[EDB-31767: MediaWiki - 'Thumb.php' Remote Command Execution (Metasploit)]
Exploit-DB: exploits/multiple/webapps/31329.txt
[EDB-31329: MediaWiki 1.22.1 PdfHandler - Remote Code Execution]
D2 Elliot: mediawiki_thumb.php_page_parameter_remote_shell_command_injection.html
[MediaWiki thumb.php page Parameter Remote Shell Command Injection]

Before running any exploit against any system, make sure you are authorized by the owner of the target system(s) to perform such activity. In any other case, this would be considered as an illegal activity.

WARNING: Beware of using unverified exploits from sources such as GitHub or Exploit-DB. These exploits and PoCs could contain malware. For more information, see how to use exploits safely.

How to Run

Here is how to run the Debian DSA-2891-1 : mediawiki, mediawiki-extensions Multiple Vulnerabilities as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Debian Local Security Checks plugin family.
On the right side table select Debian DSA-2891-1 : mediawiki, mediawiki-extensions Multiple Vulnerabilities plugin ID 73256.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl debian_DSA-2891.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a debian_DSA-2891.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - debian_DSA-2891.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state debian_DSA-2891.nasl -t <IP/HOST>

Go back to menu.
