CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in MediaWiki up to 1.x (Content Management System). It has been classified as critical. This affects the function Language::factory of the file languages/Language.php. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Multiple directory traversal vulnerabilities in (1) languages/Language.php and (2) includes/StubObject.php in MediaWiki 1.8.0 and other versions before 1.16.2, when running on Windows and possibly Novell Netware, allow remote attackers to include and execute arbitrary local PHP files via vectors related to a crafted language file and the Language::factory function.

The weakness was disclosed 02/01/2011 (Website). The advisory is shared at lists.wikimedia.org. This vulnerability is uniquely identified as CVE-2011-0537 since 01/20/2011. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1006 for this issue.

It is declared as proof-of-concept. By approaching the search of inurl:languages/Language.php it is possible to find vulnerable targets with Google Hacking. The vulnerability scanner Nessus provides a plugin with the ID 59647 (GLSA-201206-09 : MediaWiki: Multiple vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks.
