Summary

A vulnerability in the high availability service of Cisco Unified Computing 
System Fabric Interconnect could allow an unauthenticated, remote attacker to 
gain access to sensitive information and prevent the cluster service from 
syncing with its peers.

The vulnerability is due to improper binding of the cluster service to the 
management interface. An attacker could exploit this vulnerability by 
establishing a Telnet connection to the cluster service from a remote location. 
A successful exploit could allow the attacker to gain access to sensitive 
information and modify a field that results in the cluster service unable to 
sync with its peers.
