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.
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.
