APP: MediaWiki Remote Code Execution
This signature detects attempts to exploit a known flaw in the MediaWiki web application. An attacker can send a malformed request to the server which could result in arbitrary code execution on the server with the privileges of the HTTP daemon user.
Extended Description
MediaWiki 1.22.x before 1.22.2, 1.21.x before 1.21.5, and 1.19.x before 1.19.11, when DjVu or PDF file upload support is enabled, allows remote attackers to execute arbitrary commands via shell metacharacters in (1) the page parameter to includes/media/DjVu.php; (2) the w parameter (aka width field) to thumb.php, which is not properly handled by includes/media/PdfHandler_body.php; and possibly unspecified vectors in (3) includes/media/Bitmap.php and (4) includes/media/ImageHandler.php.
