therefore, affected by the following vulnerability:

  - An improper access control vulnerability exists when
    calls to application listeners do not use the appropriate
    facade object. This allows untrusted applications to
    potentially access and modify information associated
    with other web applications. 

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