Detection Guidance

This vulnerability is related to AMI's AptioV BIOS version 5.041 and involves improper handling of permissions by local access. Detection involves verifying the BIOS version on your system to see if it is version 5.041 or earlier. Since this is a BIOS vulnerability, network detection commands are not applicable. To check the BIOS version on a Windows system, you can use the command: 'wmic bios get smbiosbiosversion'. On Linux, you can use: 'sudo dmidecode -s bios-version'. If the BIOS version matches or is older than 5.041, the system is vulnerable. [1]

Mitigation Strategies

The immediate mitigation step is to update the AptioV BIOS to version 5.041 or later, where the vulnerability has been addressed. Applying the security advisory AMI-SA-2025009 update from AMI is recommended to fix the issue and prevent escalation of privileges. [1]
