MediaWiki < 1.23.10 / 1.24.3 / 1.25.2 Multiple Vulnerabilities



The remote web server is running a PHP application that is out of date


The version of MediaWiki installed is 1.23.x earlier than 1.23.10, 1.24.x earlier than 1.24.3, or 1.25.x earlier than 1.25.2. Therefore, it is affected by multiple vulnerabilities :

- A flaw exists due to 'Special:DeletedContributions' failing to properly protect the IP of autoblocked users. This may allow attackers to gain access to IP address information. (CVE-2015-6727) - A flaw exists as HTTP requests do not require multiple steps, explicit confirmation, or a unique token when performing certain sensitive actions. By tricking a user into following a specially crafted link, a context-dependent attacker can perform a Cross-Site Request Forgery (CSRF / XSRF) attack causing the victim to modify a user's watchlist. (CVE-2015-6728) - A flaw allows a reflected cross-site scripting (XSS) attack. This flaw exists because the 'thumb.php' script does not validate input to error messages before returning it to users. This may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server. (CVE-2015-6729, 2015-6730)


Upgrade to MediaWiki version 1.25.2. If 1.25.x cannot be obtained, versions 1.24.3, and 1.23.10 have also been patched for these vulnerabilities.
