CVE-2024-56182: CWE-693: Protection Mechanism Failure in Siemens SIMATIC Field PG M5
A vulnerability has been identified in SIMATIC Field PG M5 (All versions), SIMATIC Field PG M6 (All versions < V26.01.12), 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 disable the BIOS password without proper authorization by directly communicate with the flash controller.
AI Analysis
Technical Summary
This vulnerability (CVE-2024-56182) affects a broad range of Siemens SIMATIC Field PG and IPC devices by exposing insufficient protection of EFI variables. EFI variables are critical for system firmware configuration, including BIOS password settings. The flaw allows an authenticated attacker with high privileges to bypass BIOS password protection by directly interacting with the flash controller, potentially leading to full system compromise. The CVSS v3.1 score is 8.2, reflecting high impact on confidentiality, integrity, and availability. The vulnerability is categorized under CWE-693 (Protection Mechanism Failure).
Potential Impact
Successful exploitation could allow an authenticated attacker to disable BIOS password protection without proper authorization, compromising system security controls. This can lead to unauthorized system access, manipulation of firmware settings, and potential full control over the affected device. The impact affects confidentiality, integrity, and availability of the systems.
Mitigation Recommendations
Patch status is not yet confirmed — check the Siemens vendor advisory for current remediation guidance. Until an official fix is available, restrict access to authorized personnel only and monitor for unauthorized attempts to interact with EFI variables. Avoid granting unnecessary high-privilege access to reduce risk.
