CyberRota Analysis

AI-Generated

IBM Power Systems Firmware versions FW1120.00, FW1110.00 through FW1110.30, FW1060.00 through FW1060.80, and FW950.00 through FW950.H2 are vulnerable due to inadequate access controls over privileged configuration operations on the FSP. An authenticated attacker with administrator-level access can disrupt system availability by placing the managed system into a non-production mode, which persists through resets and requires manual intervention to restore. Organizations using these firmware versions should prioritize remediation to prevent potential availability issues.

Original NVD 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 access controls over privileged system configuration operations on the FSP. An attacker with authenticated administrator-level access to the FSP can place the managed system into a non-production operational mode, allowing certain system components to be disabled. This condition persists across FSP resets and requires explicit operator intervention — clearing the affected configuration — to restore normal operation. Successful exploitation results in an availability impact to the managed system.
