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. References: ber=PSN-2010-05-751&viewMode=view Credits: Richard Brain of ProCheckUp Ltd ( Legal: Copyright 2009 Procheckup Ltd.
