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.
