"According to its version number, the Centreon application hosted on
the remote web server is 2.6.x prior to 2.6.2. It is, therefore,
affected by a remote code execution vulnerability due to improper
sanitization of user-uploaded files via the main.php script. An
authenticated, remote attacker can exploit this, via the 'filename'
POST parameter, to upload a malicious PHP file to a user-accessible
path, which allows the file to be later executed by a direct request.

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
