Honeywell strongly encourages and recommends all customers running unsupported versions of EKPS prior to R400 to upgrade to a supported version.

Honeywell Experion PKS Safety Manager (SM and FSC) through 2022-05-06 has Insufficient Verification of Data Authenticity. According to FSCT-2022-0053, there is a Honeywell Experion PKS Safety Manager insufficient logic security controls issue. The affected components are characterized as: Honeywell FSC runtime (FSC-CPU, QPP), Honeywell Safety Builder. The potential impact is: Remote Code Execution, Denial of Service. The Honeywell Experion PKS Safety Manager family of safety controllers utilize the unauthenticated Safety Builder protocol (FSCT-2022-0051) for engineering purposes, including downloading projects and control logic to the controller. Control logic is downloaded to the controller on a block-by-block basis. The logic that is downloaded consists of FLD code compiled to native machine code for the CPU module (which applies to both the Safety Manager and FSC families). Since this logic does not seem to be cryptographically authenticated, it allows an attacker capable of triggering a logic download to execute arbitrary machine code on the controller's CPU module in the context of the runtime. While the researchers could not verify this in detail, the researchers believe that the microprocessor underpinning the FSC and Safety Manager CPU modules is incapable of offering memory protection or privilege separation capabilities which would give an attacker full control of the CPU module. There is no authentication on control logic downloaded to the controller. Memory protection and privilege separation capabilities for the runtime are possibly lacking. The researchers confirmed the issues in question on Safety Manager R145.1 and R152.2 but suspect the issue affects all FSC and SM controllers and associated Safety Builder versions regardless of software or firmware revision. An attacker who can communicate with a Safety Manager controller via the Safety Builder protocol can execute arbitrary code without restrictions on the CPU module, allowing for covert manipulation of control operations and implanting capabilities similar to the TRITON malware (MITRE ATT&CK software ID S1009). A mitigating factor with regards to some, but not all, of the above functionality is that these require the Safety Manager physical keyswitch to be in the right position.

Multiple stack-based buffer overflows in (1) HWOPOSScale.ocx and (2) HWOPOSSCANNER.ocx in Honeywell OPOS Suite before 1.13.4.15 allow remote attackers to execute arbitrary code via a crafted file that is improperly handled by the Open method.

An arbitrary memory write vulnerability exists in the dual_onsrv.exe module in Honeywell Experion PKS R40x before R400.6, R41x before R410.6, and R43x before R430.2, that could lead to possible remote code execution or denial of service. Honeywell strongly encourages and recommends all customers running unsupported versions of EKPS prior to R400 to upgrade to a supported version.

Honeywell ControlEdge through R151.1 uses Hard-coded Credentials. According to FSCT-2022-0056, there is a Honeywell ControlEdge hardcoded credentials issue. The affected components are characterized as: SSH. The potential impact is: Remote code execution, manipulate configuration, denial of service. The Honeywell ControlEdge PLC and RTU product line exposes an SSH service on port 22/TCP. Login as root to this service is permitted and credentials for the root user are hardcoded without automatically changing them upon first commissioning. The credentials for the SSH service are hardcoded in the firmware. The credentials grant an attacker access to a root shell on the PLC/RTU, allowing for remote code execution, configuration manipulation and denial of service.

Honeywell Experion PKS C200, C200E, C300, and ACE controllers are vulnerable to improper neutralization of special elements in output, which may allow an attacker to remotely execute arbitrary code and cause a denial-of-service condition.
