CVE-2012-5756 (websphere_datapower_xc10_appliance)

The IBM WebSphere DataPower XC10 Appliance through and through, when a collective configuration is enabled, has a single secret key that is shared across different customers' installations, which allows remote attackers to spoof a container server by (1) sniffing the network to locate a cleartext transmission of this key or (2) leveraging knowledge of this key from another installation.
