Cisco Unified Computing System Fabric Interconnect Information Disclosure Vulnerability

A vulnerability in the Fabric Interconnect of Cisco Unified Computing System could allow an unauthenticated, remote attacker to capture or modify KVM virtual media traffic.

The vulnerability is due to improperly securing the KVM virtual media traffic between the server and the client. An attacker could exploit this vulnerability by sniffing traffic or executing a man-in-the-middle attack. An exploit could allow the attacker view, or capture, the KVM virtual media traffic to collect information and possibly modify that traffic.

Cisco has confirmed the vulnerability in a security notice and released software updates.

To exploit this vulnerability, it is likely that an attacker would need access to trusted, internal networks to be positioned between the targeted device and a client transmitting KVM virtual media traffic. These conditions make it unlikely for an attacker to achieve a successful exploit.

Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
