"According to its version number, the instance of TWiki running on
the remote host is affected by multiple security vulnerabilities :

  - The '%MAKETEXT{}%' variable fails to properly sanitize
    user-supplied input. A remote attacker can exploit this
    issue to execute arbitrary shell commands on the remote
    host subject to the privileges of the web server user.
    (CVE-2012-6329)

  - The '%MAKETEXT{}%' variable fails to properly sanitize
    user-supplied input, which can lead to a denial of
    service) condition if an overly large value is passed to
    the variable. (CVE-2012-6330)

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