IBM System Networking switches information disclosure
|ibm-networking-cve20130570 (83166)||Low Risk|
A potential vulnerability has been identified in the FCoE feature in IBM System Networking switches and legacy Blade Network Technology (BNT) switches running IBM Networking Operating System (NOS) (formerly known as BLADE Operating System). If a switch receives a frame with an unknown destination MAC address, it will flood the frame out on all interfaces on the same VLAN. While this behavior is standard for Ethernet, it is not within spec for Fibre Channel over Ethernet. This vulnerability is not remotely exploitable and requires physical or local access to the network. A successful exploit requires that the attacker be eavesdropping on the broadcast domain (i.e., the VLAN). An exploit should not impact integrity of transmitted data or system availability, but it can compromise the confidentiality of information, although the attacker would not have control over what can be accessed.
