• Advisory ID: DRUPAL-SA-CONTRIB-2012-049
  • Project: ShareThis (third-party module)
  • Version: 7.x
  • Date: 2012-March-28
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting, Cross Site Request Forgery


The XSS issue is
CVE: CVE-2012-2076
The CSRF issue is
CVE: CVE-2012-2077

The ShareThis module allows you to display social networking tools to users.

The administration forms of the module do not properly use the Form API allowing a malicious user to inject unexpected settings, allowing for cross-site scripting attacks (XSS). Additionally, the module had an incomplete feature for updating these settings outside of the Form API which was vulnerable to a cross site request forgery attack.

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer sharethis".

Versions affected

  • ShareThis 7.x-2.x versions prior to 7.x-2.2.
