Detailsinfo

A vulnerability, which was classified as critical, has been found in Honeywell Safety Manager up to 5.02. Affected by this issue is an unknown part of the component Firmware Image Handler. The manipulation with an unknown input leads to a hard-coded credentials vulnerability. Using CWE to declare the problem leads to CWE-798. The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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).

The weakness was disclosed 07/29/2022 as icsa-22-207-02. The advisory is shared for download at cisa.gov. This vulnerability is handled as CVE-2022-30314 since 05/06/2022. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1110.001.
