Detailsinfo

A vulnerability was found in Siemens SIMATIC Field PG M5, SIMATIC Field PG M6, SIMATIC IPC BX-21A, SIMATIC IPC BX-32A, SIMATIC IPC BX-39A, SIMATIC IPC BX-59A, SIMATIC IPC PX-32A, SIMATIC IPC PX-39A, SIMATIC IPC PX-39A PRO, SIMATIC IPC RC-543B, SIMATIC IPC RW-543A, SIMATIC IPC127E, SIMATIC IPC227E, SIMATIC IPC227G, SIMATIC IPC277E, SIMATIC IPC277G, SIMATIC IPC277G PRO, SIMATIC IPC3000 SMART V3, SIMATIC IPC327G, SIMATIC IPC347G, SIMATIC IPC377G, SIMATIC IPC427E, SIMATIC IPC477E, SIMATIC IPC477E PRO, SIMATIC IPC527G, SIMATIC IPC627E, SIMATIC IPC647E, SIMATIC IPC677E, SIMATIC IPC847E and SIMATIC ITP1000. It has been rated as critical. This issue affects some unknown processing of the component Extensible Firmware Interface. The manipulation with an unknown input leads to a protection mechanism vulnerability. Using CWE to declare the problem leads to CWE-693. The product does not use or incorrectly uses a protection mechanism that provides sufficient defense against directed attacks against the product. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at cert-portal.siemens.com. The identification of this vulnerability is CVE-2024-56182 since 12/18/2024. The exploitation is known to be easy. An attack has to be approached locally. Additional levels of successful authentication are needed for exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 04/15/2026).

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2024-54269). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
