SA-CONTRIB-2013-021 - Display Suite - Cross Site Scripting (XSS)

Display Suite allows you to take full control over how your content is displayed using a drag and drop interface.

In certain situations, Display Suite does not properly sanitize user-supplied data, allowing a malicious user to embed scripts within a page, resulting in a Cross-site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that the site must use a contributed module that alters usernames such as the realname module and the author field must be displayed as plain text “author”.

CVE identifier(s) issued

• CVE-2013-0323

Versions affected

• Display Suite 7.x-1.x versions prior to 7.x-1.7.
• Display Suite 7.x-2.x versions prior to 7.x-2.1.

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

Solution

Install the latest version:

• If you use the Display Suite module for Drupal 7.x-1.x, upgrade to Display Suite 7.x-1.7
• If you use the Display Suite module for Drupal 7.x-2.x, upgrade to Display Suite 7.x-2.1
