Summary

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.

Risk Assessment

The risk includes potential takeover of the service processor, leading to full system compromise, data confidentiality breach, and service disruption.

Recommendation

It is recommended to immediately update the firmware to a version containing fixes. Also, restrict administrator access to the FSP to trusted and necessary personnel only.

Other vulnerabilities in IBM Server Firmware

CVE-2026-93306High
IBM Server Firmware versions FW1120.00 through FW1120.01, FW1110.00 through FW1110.31, FW1060.00 through FW1060.81, and FW950.00 through FW950.H3 is affected by a vulnerability in the ASMI web interface. An unauthenticated attacker on the management network can send a malformed HTTPS request to ASMI, causing the web server to crash with possible memory corruption and generate an error log. The ASMI web interface restarts automatically, but repeated exploitation could result in a sustained loss of access to the ASMI management interface.
