Description


A vulnerability has been discovered in the Link module for Drupal, which can be exploited by malicious users to conduct script insertion attacks.

Input passed via the "description" parameter in index.php (when "q" is set to "admin/content/types/[TYPE NAME]/fields/[FIELD NAME]") is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in the context of an affected site when the malicious type is viewed.

Successful exploitation of this vulnerability requires the "administer content types" permission.

This vulnerability is confirmed in version 5.x-2.5. Other versions may also be affected.


Solution:
Grant the "administer content types" privilege to trusted users only.
