   * Advisory ID: DRUPAL-SA-CONTRIB-2014-058
   * Project: Webserver authentication [1] (third-party module)
   * Version: 7.x
   * Date: 2014-May-28
   * Security risk: Less critical [2]
   * Exploitable from: Remote
   * Vulnerability: Access bypass

-------- DESCRIPTION
---------------------------------------------------------

This module allows you to delegate user authentication to the web server.
The module can be configured to automatically create users that have been
authenticated by the web server.
There was an issue where a configuration variable did not have consistent
default values in the code meaning that in a new install users would be
created by default even though the config screen would suggest otherwise.
This vulnerability is mitigated by the fact that the issue is only present if
the site owner has not saved the configuration page and it is very common to
configure a module after installing it.
