"According to its version number, the X2Engine application installed on
the remote web server is potentially affected by multiple
vulnerabilities :

  - A PHP object injection vulnerability exists which can be
    used to carry out Server-Side Request Forgery (SSRF)
    attacks using specially crafted serialized objects. An
    attacker can exploit this issue by sending a crafted
    serialized request via the 'report' HTTP POST parameter
    of the 'SiteController.php' script. (CVE-2014-5297)

  - A file upload vulnerability exists in the script
    'FileUploadsFilter.php' due to a case-sensitive file
    name check by the regex contained in the constant
    'FileUploadsFilter::EXT_BLACKLIST'. An attacker, using a
    crafted file name with capital letters in the extension,
    can bypass file upload restrictions to load and execute
    arbitrary PHP scripts, provided the X2Engine is running
    under a case-insensitive file system or configuration.
    (CVE-2014-5298)

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