If you cannot patch yet, restrict access to devices to trusted administrators only and monitor for unauthorized changes to EFI variables or secure boot settings. Follow Siemens' official security advisories for updates and remediation instructions.
Description
A high-severity vulnerability (CVE-2024-56181) affects multiple Siemens SIMATIC industrial PC models and Field PG M5 devices. The issue involves insufficient protection of EFI variables, allowing an authenticated attacker with high privileges to alter the secure boot configuration by directly communicating with the flash controller. This vulnerability impacts device integrity and security, potentially enabling compromise of the boot process.
