Summary

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.

Risk Assessment

Repeated exploitation could cause a sustained loss of access to the ASMI management interface, impacting the integrity and availability of the server management system.

Recommendation

Update IBM server firmware to a version containing the fix. Restrict ASMI interface access to the trusted management network only.

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.

Original NVD description (English source)

IBM Server Firmware 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 will restart automatically; however, repeated exploitation could result in a sustained loss of access to the ASMI management interface, resulting in an integrity and availability impact.
