"The remote web server is running a version of Drupal that is 6.x prior
to 6.30. It is, therefore, affected by a security bypass vulnerability
in the OpenID module that could allow an authenticated attacker to
hijack other users' accounts. Only user accounts associated with one
or more OpenID entities are affected.

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