MediaWiki installations starting with version 1.8 are affected. One point of reference is in order for an attack to succeed, a victim, or an attacker, must enable a specific non-default setting.

As a result of the vulnerability, the WikiMedia Foundation fixed the problem after they received notification. The organization also sent out an alert to encourage MediWiki customers to update their installations.

If unpatched, the vulnerability could inject malicious code into and other Wiki websites that run on the open-source platform MediaWiki. This could have been a problem since Wikipedia has 94 million unique visitors each month.

“It only takes a single vulnerability on a widely adopted platform for a hacker to infiltrate and wreak widespread damage. The Check Point Vulnerability Research Group focuses on finding these security exposures and deploying the necessary real-time protections to secure the Internet,” said Dorit Dor, vice president of products at Check Point Software Technologies.

Check Point said this is the third remote code execution vulnerability found on the MediaWiki platform since 2006.

Last year, there were 13 security holes found in MediaWiki. The list includes one code execution, six cross-site scripting (XSS), two bypass and three cross-site reference forgery (CSRF) vulnerabilities.
