[Security-news] SA-CONTRIB-2011-022 - Cosign - SQL Injection

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2011-022
  * Project: cosign [1] (third-party module)
  * Version: 6.x
  * Date: 2011-MONTH-XX
  * Security risk: Less critical [2]
  * Exploitable from: Remote
  * Vulnerability: SQL Injection

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

Under certain conditions the module deletes uid 1 and then does an
unparameterized db_query to insert a new uid 1.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission "administer site configuration" and must be able to
remotely manipulate the web server environmental variables REMOTE_USER and
REMOTE_REALM.

-------- VERSIONS AFFECTED  
---------------------------------------------------

  * 6.x-1.4
  * 6.x-1.5
  * 6.x-1.6

Drupal core is not affected. If you do not use the contributed cosign [3]
module, there is nothing you need to do.

-------- SOLUTION  
------------------------------------------------------------

Install the latest version:

  * If you use the Cosign module for Drupal 6.x, upgrade to version 6.x-1.7.

See also the cosign [4] project page.

-------- REPORTED BY

  * Steven Merrill [5]

-------- FIXED BY  
------------------------------------------------------------

  * Kris Steinhoff [6] the module maintainer
