Some vulnerabilities have been reported in Drupal Core, which can be exploited by malicious users to conduct script insertion attacks.

1) Input passed to the "Category" input field of the Contact module's administration page is not properly sanitised before being displayed to the user. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.

Successful exploitation requires the "administer site-wide contact form" privilege.

2) Certain unspecified input passed to the Menu module's administration page is not properly sanitised before being displayed in the menu administration overview. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.

Successful exploitation requires the privilege to create new menus.

The vulnerabilities are reported in Drupal Core 6.x prior to 6.15.

Solution
Update to Drupal Core 6.15 or apply patch.
