Description
A vulnerability in Cisco Jabber for Windows could allow an unauthenticated, local attacker to access sensitive communications made by the Jabber client. An attacker could exploit this vulnerability to gain information to conduct additional attacks. The vulnerability is due to the way Cisco Jabber for Windows handles random number generation for file folders. An attacker could exploit the vulnerability by fixing the random number data used to establish Secure Sockets Layer (SSL) connections between clients.
