CVE-2015-2941

CVSS v2.0

4.3

Medium

VectorAV:N/AC:M/Au:N/C:N/I:P/A:N
Name of the Vulnerable Software and Affected Versions MediaWiki versions prior to 1.19.24 MediaWiki versions 1.20.x through 1.23.9 MediaWiki versions 1.24.x through 1.24.2
Description A cross-site scripting issue exists, allowing remote attackers to inject arbitrary web script or HTML via an invalid parameter in a wddx format request to "api.php". This occurs because the error message is not properly handled when using HHVM, related to unsafe calls to wddx serialize value.
Recommendations For MediaWiki versions prior to 1.19.24, update to version 1.19.24 or later. For MediaWiki versions 1.20.x through 1.23.9, update to version 1.23.9 or later. For MediaWiki versions 1.24.x through 1.24.2, update to version 1.24.2 or later. As a temporary workaround, consider restricting access to the "api.php" endpoint until a patch is available.
