SA-CORE-2014-005 - Drupal core - SQL injection (Highly Critical)

Posted by Drupal Security Team on 

Description

Drupal 7 includes a database abstraction API to ensure that queries executed against the database are sanitized to prevent SQL injection attacks.
A vulnerability in this API allows an attacker to send specially crafted requests resulting in arbitrary SQL execution. Depending on the content of the requests this can lead to privilege escalation, arbitrary PHP execution, or other attacks.
This vulnerability can be exploited by anonymous users.
Update: Multiple exploits have been reported in the wild following the release of this security advisory, and Drupal 7 sites which did not update soon after the advisory was released may be compromised. See this follow-up announcement for more information:https://www.drupal.org/PSA-2014-003

CVE identifier(s) issued

  • CVE-2014-3704

Versions affected

  • Drupal core 7.x versions prior to 7.32.

Solution

Install the latest version:
If you are unable to update to Drupal 7.32 you can apply this patch to Drupal's database.inc file to fix the vulnerability until such time as you are able to completely upgrade to Drupal 7.32.
