"According to its self-reported version number, the Joomla!
installation running on the remote web server is prior to 3.4.6. It
is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists due to
    improper sanitization of session values. An
    unauthenticated, remote attacker can exploit this to
    execute arbitrary code. (CVE-2015-8562)

  - A cross-site request forgery (XSRF) vulnerability exists
    due to HTTP requests to com_templates not requiring
    multiple steps, 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
    cause the user to perform unspecified actions.
    (CVE-2015-8563)

  - A path traversal vulnerability exists due to improper
    sanitization of user-supplied input via the XML install
    file. (CVE-2015-8564)

  - A path traversal vulnerability exists due to improper
    sanitization of input supplied via user requests.
    (CVE-2015-8565)

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