"According to its self-reported version number, the Joomla!
installation running on the remote web server is 3.x prior to 3.2.3.
It is, therefore, affected by multiple vulnerabilities :

  - A SQL injection vulnerability exists within
    weblinks-categories due to improper sanitization of
    user-supplied input to the category 'ID' parameter
    before using it in SQL queries. An unauthenticated,
    remote attacker can exploit this to inject or manipulate
    SQL queries against the back-end database, resulting in
    the manipulation or disclosure of arbitrary data.
    (CVE-2014-7981)

  - An unspecified cross-site scripting (XSS) vulnerability
    exists due to improper validation of input before
    returning it to users. An unauthenticated, remote
    attacker can exploit this, via a specially crafted
    request, to execute arbitrary script code in a user's
    browser session. (CVE-2014-7982)

  - A cross-site scripting (XSS) vulnerability exists within
    the index.php/single-contact script due to improper
    validation of input to the 'jform[contact_email]' POST
    parameter before returning it to users. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted request, to execute arbitrary script
    code in a user's browser session. (CVE-2014-7983)

  - A security bypass vulnerability exists that allows a
    remote attacker to bypass intended restrictions and log
    into the system using GMail credentials. (CVE-2014-7984)

  - A SQL injection vulnerability exists in the
    ModTagssimilarHelper::getList() function within file
    modules/mod_tags_similar/helper.php due to improper
    sanitization of user-supplied input before using it in
    SQL queries. An unauthenticated, remote attacker can
    exploit this to inject or manipulate SQL queries against
    the back-end database, resulting in the manipulation or
    disclosure of arbitrary data.

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