Drupal Services Single Sign-On Client Module Cross Site Scripting Vulnerability



The Services Single Sign-On Client module for Drupal is prone to a cross-site scripting vulnerability because it fails to properly sanitize user-supplied text.

An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

Services Single Sign-On Client 7.x-1.x-dev prior to 7.x-1.6 are affected.
