Vulnerability Description:  
  
A permanent Cross Site Scripting vulnerability was found in Achievo 1.4.2, because the application  
fails to sanitize user-supplied input. The vulnerability can be triggered by any logged-in user who is  
able to add a Scheduler Category.  
  
Proof of Concept:  
  
  
* Add <script>alert(“XSS in Category”);</script> as a new category. Then, browse the Scheduler.  
  
  
Impact:  
  
An affected user may unintentionally execute scripts or actions written by an attacker. In addition, an  
attacker may obtain authorization cookies that would allow him to gain unauthorized access to the  
application.  
  
Solution:  
  
New category is now correctly sanitized.
