GFI HelpDesk before 4.99.9 contains a stored cross-site scripting vulnerability in the Troubleshooter module where the subject POST parameter is not sanitized in Controller_Step.InsertSubmit() and EditSubmit() before being rendered by View_Step.RenderViewSteps(). An authenticated staff member can inject arbitrary JavaScript into the step subject field, and the payload executes when any user navigates to Troubleshooter > View Troubleshooter and clicks the affected step link.
