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 ASMI web interface. An unauthenticated attacker with network access can send the FSP a malformed request, allowing arbitrary code execution, giving the attacker full control over the managed system, resulting in a confidentiality, integrity, and availability impact.
Protect access to the FSP's network interface.
