IBM Server 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 firmware update process. An attacker with authenticated administrator-level access to the FSP can, under specific conditions, execute arbitrary code, resulting in a confidentiality, integrity, and availability impact.
