Honeywell Experion PKS Safety Manager 5.02 uses Hard-coded Credentials. According to FSCT-2022-0052, there is a Honeywell Experion PKS Safety Manager hardcoded credentials issue. The affected components are characterized as: POLO bootloader. The potential impact is: Manipulate firmware. The Honeywell Experion PKS Safety Manager utilizes the DCOM-232/485 serial interface for firmware management purposes. When booting, the Safety Manager exposes the Enea POLO bootloader via this interface. Access to the boot configuration is controlled by means of credentials hardcoded in the Safety Manager firmware. The credentials for the bootloader are hardcoded in the firmware. An attacker with access to the serial interface (either through physical access, a compromised EWS or an exposed serial-to-ethernet gateway) can utilize these credentials to control the boot process and manipulate the unauthenticated firmware image (see FSCT-2022-0054).

ICSA-22-207-02 — Honeywell Safety Manager

The affected product uses the unauthenticated Safety Builder protocol, which does not validate or authenticate the download logic. This could allow an attacker to preform remote code execution on the CPU module. The affected product utilizes the Safety Builder protocol, which does not have native authentication. An attacker capable of invoking the protocols' functionalities could cause configuration and system changes. The affected product access to the boot configuration is controlled by credentials hard-coded in the Safety Manger firmware. This could allow an attacker with serial interface access to control the boot process and manipulate the firmware image. The affected product firmware images are not signed and only rely on insecure checksums for regular integrity checks. This could allow an attacker with access to the serial interface to control the boot process or push malicious firmware.
