What is CVE-2022-30314?

The Honeywell Experion PKS Safety Manager 5.02 is susceptible to a vulnerability involving hard-coded credentials in its firmware. The issue affects the POLO bootloader, which is exposed through the DCOM-232/485 serial interface during the boot process. When accessed, these hard-coded credentials can potentially allow an attacker with physical or network access to manipulate the boot configuration and control the firmware image. This exploitation can lead to unauthorized firmware management, highlighting the importance of securing access interfaces in safety-critical environments.
