"According to its version number, the Centreon application hosted on
the remote web server is version 2.6.x prior to 2.6.5. It is,
therefore, affected by multiple vulnerabilities :

  - A cross-site request forgery (XSRF) vulnerability exists
    in the main.php script. A remote attacker can exploit
    this to perform administrative actions by convincing a
    user to follow a link to a malicious website.

  - A flaw exists in the main.php script due to improper
    sanitization of user-supplied input to the POST
    'persistent' parameter. An authenticated, remote
    attacker can exploit this to execute arbitrary shell
    commands.

  - A cross-site scripting vulnerability exists in the
    main.php script due to improper sanitization of
    user-supplied input to the 'img_comment' POST parameter.
    An authenticated, remote attacker can exploit this, via
    a crafted request, to execute arbitrary script code in a
    user's browser session.

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