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), 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), SIMATIC IPC477E (All versions), SIMATIC IPC477E PRO (All versions), 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) affects a broad range of Siemens SIMATIC Field PG M5 and various SIMATIC IPC devices across multiple versions. The root cause is insufficient protection of EFI variables, which are critical for secure boot processes. An authenticated attacker with high privileges can exploit this weakness to modify secure boot configurations by interacting directly with the flash controller, potentially compromising system security. The CVSS v3.1 score is 8.2, indicating a high severity with local attack vector, low attack complexity, high privileges required, no user interaction, and impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an authenticated attacker with high privileges to alter secure boot configurations, potentially undermining the device's trusted boot process. This can lead to full compromise of system integrity, confidentiality, and availability. The vulnerability affects a wide range of Siemens industrial computing devices, which are often used in critical infrastructure and industrial environments.
Mitigation Recommendations
Patch status is not yet confirmed — check the Siemens vendor advisory for current remediation guidance. Since no patch or official fix information is provided, organizations should monitor Siemens advisories closely. Until a fix is available, restrict access to authenticated users with high privileges and limit direct communication with the flash controller to trusted processes only.
