Check Point researchers discovered that this critical vulnerability left MediaWiki (version 1.8 onwards) exposed to remote code execution (RCE), where an attacker can gain complete control of the vulnerable web server. Check Point immediately alerted the WikiMedia Foundation about the vulnerability, and after verification, the Foundation issued an update and patch to the MediaWiki software. Check Point also delivered updated protections to its worldwide customers in conjunction with the WikiMedia Foundation's software update.
If the vulnerability had not been uncovered, an attacker would have been able to control the Wikipedia.org Web server, or any other 'wiki' site running on MediaWiki, and potentially inject and serve malware-infecting code to users visiting these sites
The WikiMedia Foundation released a software update after learning of the vulnerability from Check Point and encouraged all MediaWiki customers to apply the patch as soon as possible
Since 2006, this is only the third RCE vulnerability found in the MediaWiki platform
Check Point's Vulnerability Research Group regularly performs assessments of common software to ensure the security of Internet users worldwide. Customers with the Check Point Intrusion Prevention System (IPS) Software Blade automatically received detections for this vulnerability.
"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. We're pleased that the MediaWiki platform is now protected against attacks on this vulnerability, which would have posed great security risk for millions of daily 'wiki' site users," said Dorit Dor, vice president of products at Check Point Software Technologies.
