"According to its self-reported version number, the Joomla!
installation running on the remote web server is 2.5.x prior to
2.5.25, 3.x prior to 3.2.5, or 3.3.x prior to 3.3.4. It is, therefore,
affected by multiple vulnerabilities :

  - A cross-site scripting (XSS) vulnerability exists in the
    com_media component due to improper sanitization of
    input before returning it to users. An unauthenticated,
    remote attacker can exploit this, via a specially
    crafted request, to execute arbitrary script code within
    a user's browser session. Note that this issue only
    affects versions 3.2.x prior to 3.2.5 and 3.3.x prior to
    3.3.4. (CVE-2014-6631)

  - An authentication bypass vulnerability exists in the
    LDAP extension due to a failure to restrict NULL bytes.
    An unauthenticated, remote attacker can exploit this,
    via a specially crafted request, to bypass LDAP
    authentication and login as a different user without
    knowing the user's password. (CVE-2014-6632)

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