A HTTP injection flaw was found in the way Plone, a user friendly and powerful content management system, performed sanitization of HTTP cookie values provided within certain URL requests. A remote attacker could provide a specially-crafted URL that, then visited by an authenticated Plone user would lead to arbitrary HTML or web script execution in the context of the Plone user's session.
