6.0.x prior to 6.0.14. It is, therefore, affected by multiple
vulnerabilities :

  - An unspecified flaw exists that allows an authenticated,
    remote attacker to gain elevated privileges.

  - An unspecified flaw exists in the policy configuration
    dialog that allows an authenticated, remote attacker to
    have an unspecified impact.

  - A boundary check error exists in the Captive Portal that
    allows a remote attacker to cause a denial of service.
