Cisco Unified Computing System contains a vulnerability that could allow an unauthenticated, remote attacker to gain access to sensitive information. Updates are not available.
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.
