"According to its self-reported version number, the Joomla!
installation running on the remote web server is 3.x prior to 3.4.2.
It is, therefore, affected by multiple vulnerabilities :

  - A cross-site request forgery (XSRF) vulnerability exists
    due to a failure to require explicit confirmation or a
    unique token when performing certain sensitive actions.
    An unauthenticated, remote attacker can exploit this, by
    convincing a user to follow a specially crafted link, to
    upload arbitrary code. (CVE-2015-5397)

  - An open redirect vulnerability exists due to a failure
    to validate certain script parameters. An
    unauthenticated, remote attacker can exploit this, by
    convincing a user to follow a specially crafted link, to
    redirect the user to an arbitrary website.
    (CVE-2015-5608)

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