Cisco Unified Computing System Software contains a vulnerability that could allow an unauthenticated, remote attacker to gain access to sensitive information. Updates are available.
To exploit this vulnerability, an attacker must be able to establish a Telnet connection to the cluster service from a remote location. It is likely that this cluster service would reside on a device in an internal trusted network to which an attacker would need access. In addition, the attacker would need to know the name or IP address associated with the targeted device in an attempt to establish a connection.
It is recommended to use SSH instead of Telnet, as SSH is the more secured method of establishing remote connections.
Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.
