CWE-200

Summary

A vulnerability in the web interface of Cisco Jabber for Windows Client could
allow an authenticated, local attacker to retrieve user profile information, 
which could lead to the disclosure of confidential information.

The vulnerability is due to a lack of input- and validation-checking 
mechanisms in the system. An attacker could exploit this vulnerability by 
issuing specific commands after authenticating to the system. A successful 
exploit could allow the attacker to view profile information where only 
certain parameters should be visible.
