Vulnerability Published: 2014-01-28
Patch Published: 2014-01-28
CVE [?]: CVE-2014-1610
CPE [?]: cpe:/a:mediawiki:mediawiki

Synopsis

The remote web server contains an application that is affected by multiple remote code execution vulnerabilities.

Description

According to its version number, the instance of MediaWiki running on the remote host is affected by the following remote code execution vulnerabilities :

- A user-input validation error exists during thumbnail generation in the 'thumb.php' script that allows the execution of arbitrary shell commands via a specially crafted DjVu file.

- A user-input validation error exists in the 'pdfhandler_body.php' script used by the PdfHandler extension that allows the execution of arbitrary shell commands via a specially crafted PDF file.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number. Also note that the affected features are not enabled by default.

Solution

Upgrade to MediaWiki version 1.19.11 / 1.21.5 / 1.22.2 or later.

Public Exploits

Target Network Port(s): 80
Target Asset(s): Services/www
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 MediaWiki < 1.19.11 / 1.21.5 / 1.22.2 Multiple Remote Code Execution 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)]
