CVE-2024-56181: CWE-693: Protection Mechanism Failure in Siemens SIMATIC Field PG M5
A vulnerability has been identified in SIMATIC Field PG M5 (All versions), SIMATIC IPC BX-21A (All versions < V31.01.07), SIMATIC IPC BX-32A (All versions < V29.01.07), SIMATIC IPC BX-39A (All versions < V29.01.07), SIMATIC IPC BX-59A (All versions < V32.01.04), SIMATIC IPC PX-32A (All versions < V29.01.07), SIMATIC IPC PX-39A (All versions < V29.01.07), SIMATIC IPC PX-39A PRO (All versions < V29.01.07), SIMATIC IPC RC-543A (All versions < V36.01.03), SIMATIC IPC RC-543B (All versions < V35.01.12), SIMATIC IPC RW-543A (All versions < V1.1.4), SIMATIC IPC RW-543B (All versions < V35.02.10), SIMATIC IPC127E (All versions < V27.01.11), SIMATIC IPC227E (All versions), SIMATIC IPC227G (All versions < V28.01.14), SIMATIC IPC277E (All versions), SIMATIC IPC277G (All versions < V28.01.14), SIMATIC IPC277G PRO (All versions < V28.01.14), SIMATIC IPC3000 SMART V3 (All versions), SIMATIC IPC327G (All versions < V28.01.14), SIMATIC IPC347G (All versions), SIMATIC IPC377G (All versions < V28.01.14), SIMATIC IPC427E (All versions < V21.01.21), SIMATIC IPC477E (All versions < V21.01.21), SIMATIC IPC477E PRO (All versions < V21.01.21), SIMATIC IPC527G (All versions), SIMATIC IPC627E (All versions < V25.02.15), SIMATIC IPC647E (All versions < V25.02.15), SIMATIC IPC677E (All versions < V25.02.15), SIMATIC IPC847E (All versions < V25.02.15), SIMATIC ITP1000 (All versions). The affected devices have insufficient protection mechanism for the EFI(Extensible Firmware Interface) variables stored on the device. This could allow an authenticated attacker to alter the secure boot configuration without proper authorization by directly communicate with the flash controller.
AI Analysis
Technical Summary
This vulnerability (CVE-2024-56181) impacts a wide range of Siemens SIMATIC devices, including Field PG M5 and various IPC models. It involves a protection mechanism failure (CWE-693) where EFI variables stored on the device are inadequately protected. An attacker with authenticated high privileges can modify secure boot configurations by communicating directly with the flash controller, bypassing intended authorization controls. The CVSS 3.1 base score is 8.2, reflecting high impact on confidentiality, integrity, and availability. No patch or official fix is currently documented.
Potential Impact
Successful exploitation allows an authenticated attacker with high privileges to alter secure boot configurations, potentially undermining device security controls and enabling persistent compromise. This affects confidentiality, integrity, and availability of the affected Siemens SIMATIC devices.
Mitigation Recommendations
Patch status is not yet confirmed — check the Siemens vendor advisory for current remediation guidance. Until a fix is available, restrict access to authorized personnel only and monitor for unusual activity related to EFI variable modifications. Avoid granting unnecessary high-level privileges to users on affected devices.
