4. VULNERABILITY DESCRIPTION  
----------------------------  
Multiple Non-Persistent Cross-Site Scripting vulnerabilities have been  
identified in the Watchguard Server Center v11.7.4 Update #1.  
  
Due to improper input - validation of the following GET parameters, an  
attacker could temporarily inject arbitrary code with required  
authenticated user interaction into the context of the Watchguard Server  
Center / current browser session. Successful exploitation of these  
vulnerabilities allows for example cookie theft, session hijacking or  
client side context manipulation.
