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 < 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 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. An authenticated attacker with high privileges could exploit this weakness to disable BIOS password protection by interacting directly with the flash controller. The CVSS 3.1 base score is 8.2, reflecting high impact on confidentiality, integrity, and availability. The vulnerability is categorized under CWE-693 (Protection Mechanism Failure). No known exploits are reported in the wild, and no patch or mitigation details are currently provided.
Potential Impact
Successful exploitation allows an authenticated attacker to bypass BIOS password protection, potentially leading to unauthorized firmware or system configuration changes. This compromises device security at a fundamental level, affecting confidentiality, integrity, and availability of the affected 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 authenticated access to trusted personnel only and monitor for unauthorized attempts to access EFI variables or flash controller interfaces.
