CVE-2022-30314

Firmware manipulation via hard-coded bootloader credentials

Published Jul 28, 2022 · Updated Aug 3, 2024

Hard-coded credentials in Honeywell Experion PKS Safety Manager before R160.1 allow physically proximate attackers to manipulate firmware. At boot, the DCOM-232/485 serial interface exposes the Enea POLO bootloader, whose boot-configuration access accepts credentials embedded in firmware. Access to the serial interface—directly, through a compromised engineering workstation, or through a serial-to-Ethernet gateway—is required, after which the boot process and unauthenticated firmware image can be altered.
