Consequences:

An attacker may be able to cause execution of malicious scripting code
in the browser of a user who clicks on a link or visits a malicious
webpage. The malicious code would run in the security context of the
vulnerable website.

This type of attack can result in non-persistent defacement of the
target site, or the redirection of confidential information (i.e.:
passwords or session IDs) to unauthorised third parties.


Fix:

Update to version 6.5R3.1 (build 15255) or a later version.
