• Advisory ID: DRUPAL-SA-2008-030
  • Project: Site Documentation (third-party module)
  • Versions: 5.x and 6.x
  • Date: 2008-May-14
  • Security risk: Highly critical
  • Exploitable from: Remote
  • Vulnerability: Privilege escalation


The contributed module Site Documentation intends to assist developers and administrators when they start working with a new site by showing them information from the database.

All users with the "access content" permission are able to use the module to list arbitrary tables from the database. In typical scenarios, both anonymous and authenticated users have the "access content" permission.

Access to arbitrary tables enables an attacker to impersonate users by using SESSION IDs obtained from the database. An attacker could use specifically crafted URLs to gain access to additional private information, including, but not limited to, all usernames, password hashes, and e-mail addresses.

Versions affected

  • Site Documentation for Drupal 5.x before Site Documentation 5.x-1.8
  • Site Documentation for Drupal 6.x before Site Documentation 6.x-1.1

Drupal core is not affected. If you do not use the contributed Site Documentation module, there is nothing you need to do.
