Description

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-543B (All versions), SIMATIC IPC RW-543A (All versions), SIMATIC IPC127E (All versions), SIMATIC IPC227E (All versions), SIMATIC IPC227G (All versions), SIMATIC IPC277E (All versions), SIMATIC IPC277G (All versions), SIMATIC IPC277G PRO (All versions), SIMATIC IPC3000 SMART V3 (All versions), SIMATIC IPC327G (All versions), SIMATIC IPC347G (All versions), SIMATIC IPC377G (All versions), 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.
