Summary
IBM Power Systems Firmware FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 is affected by a vulnerability in the FSP management network protocol. An unauthenticated attacker on the management network can bypass authentication and perform any administrative operation on the managed system, including control of partition power state, configuration, and console access across all hosted partitions, resulting in a confidentiality, integrity, and availability impact to the managed system.
