MediaWiki < 1.19.23 / 1.22.15 / 1.23.8 / 1.24.1 Multiple Vulnerabilities
medium Nessus Network Monitor Plugin ID 8611
Synopsis
The remote web server is running a PHP application that is affected by a security bypass and cross-site scripting vulnerability.Description
In versions older than 1.24.1, 1.22.15 or 1.19.23 or 1.23.8, MediaWiki contains a flaw in API handling which allows an attacker to bypass authentication. This issue occurs when a website includes an allowed domain as part of its name in '$wgCrossSiteAJAXdomains' in API calls. An attacker can exploit this issue to bypass CORS restrictions. Older versions of MediaWiki are also prone to a cross-site scripting vulnerability because 'thumb.php' script fails to properly sanitize user-supplied input when handling wikitext messages before returning it to the users.Solution
Upgrade to MediaWiki version 1.24.1. Alternatively, versions 1.19.23, 1.22.15, and 1.23.8 or later are patched for these vulnerabilities.See Also
