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.

As an impact it is known to affect integrity. The summary by CVE is:

MediaWiki before 1.19.6 and 1.20.x before 1.20.5 allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated by a CDATA section containing valid UTF-7 encoded sequences in a SVG file, which is then incorrectly interpreted as UTF-8 by Chrome and Firefox.

The weakness was presented 11/17/2013 by Jan Schejbal (Website). The advisory is shared at lists.wikimedia.org. This vulnerability is known as CVE-2013-2031 since 02/19/2013. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1059.007 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 73256 (Debian DSA-2891-1 : mediawiki, mediawiki-extensions Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 12787 (Mediawiki SVG Files Cross-Site Scripting and Password Reset Security Bypass Vulnerabilities).

Upgrading to version 1.14.0 eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (73256), SecurityFocus (BID 59594†), Secunia (SA55433†) and Vulnerability Center (SBV-39711†). See VDB-11233, VDB-12002, VDB-12011 and VDB-12012 for similar entries.
