high Nessus Plugin ID 72618

Language:

Synopsis

The remote web server contains an application that is affected by a remote command injection vulnerability.

Description

The version of MediaWiki running on the remote host is affected by a remote command injection vulnerability due to a failure to properly sanitize user-supplied input to the 'w' parameter in the 'thumb.php' script. A remote, unauthenticated attacker can exploit this issue to execute arbitrary commands and/or execute arbitrary code on the remote host.

Note that the application is also affected by an additional command injection issue. However, Nessus has not tested for this additional issue.

Note also that PDF file upload support and the PdfHandler extension must be enabled in order to exploit this issue.

Solution

Upgrade to MediaWiki 1.19.11 / 1.21.5 / 1.22.2 or later, and update the PdfHandler extension to the latest available version.
