"According to its version number, the instance of MediaWiki running on the remote host is affected by the following remote code execution vulnerabilities :

 - A user-input validation error exists during thumbnail
   generation in the 'thumb.php' script that allows the
   execution of arbitrary shell commands via a specially
   crafted DjVu file.

 - A user-input validation error exists in the
   'pdfhandler_body.php' script used by the PdfHandler
   extension that allows the execution of arbitrary shell
   commands via a specially crafted PDF file.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number. Also note that the affected features are not enabled by default.");
