Description
Justin C. Klein Keane has reported a vulnerability in the Link To Us module for Drupal, which can be exploited by malicious users to conduct script insertion attacks.

Input passed to the "Link page header" form field in Administer->Site Configuration->Link to Us is not properly sanitised before being stored. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed by clicking "Share this page".

Successful exploitation requires valid user credentials.

The vulnerability is reported in version 5.x-1.0.

Solution
Update to version 5.x-1.1.
