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.

+/log/device?sn=random&cluster_id=random&l_t=tr&name=<XSS>
