Technical Description
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 attacker who can lure a logged-in ASMI administrator to visit a crafted web page can, under specific conditions, silently perform administrative actions on the FSP on behalf of that administrator, resulting in a confidentiality, integrity, and availability impact to the managed system.
Remediation
Check the references section for vendor advisories and patches from ibm. Update power_system_e1080_\(9080-hex\)_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
