Drupal 6.x < 6.36 OpenID Security Bypass
Medium Nessus Network Monitor Plugin ID 9214
SynopsisThe remote web server is hosting an outdated installation of Drupal that is vulnerable to multiple attack vectors.
DescriptionThe remote web server is running a version of Drupal that is 6.x prior to 6.36. It is, therefore, potentially affected by a security bypass vulnerability due to a flaw in the OpenID module. A remote attacker can exploit this flaw to log in as other users, including administrators. Note that victims must have an existing OpenID account from a particular set of OpenID providers including, but not limited to, Verisign, LiveJournal, or StackExchange.
SolutionUpgrade to Drupal 6.36, or later.
