Vendor: IBM / http://www.ibm.com
Affected Products: Rational ClearQuest Web / Version 7.0.0.0
Vulnerability: Cross Site Scripting
Risk: HIGH

________________________________________________________________________

Vendor communication: None.

Overview:
Rational ClearQuest provides flexible workflow management, defect and 
change tracking across the application life cycle for better insight, 
predictability and control.

Description:
The flaw was found while logging a defect for another application, only
to find out Cq was also vulnerable.

Whilst logging a defect, upload a txt file as an attachment to the
defect.  Put whatever <script></script> you wish into the txt file and
it will execute when another user tries to open the attachment.
This could lead to session details (cqwebsession, JSESSIONID etc) being
disclosed to a third party and used to hijack the users session.
Finally, the Cross Site Scripting vulnerability also affects the summary
page, which is PHProjekt's index page.
