Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Honeywell ControlEdge PLC/RTU devices contain hardcoded SSH credentials embedded in the firmware. The root user account on port 22/TCP uses static credentials that do not change upon initial commissioning, enabling unauthenticated attackers to gain root shell access and achieve remote code execution, modify configurations, or cause denial of service.

MitigationReplace hardcoded credentials with unique, strong passwords changed during commissioning; disable root SSH access if possible; implement network segmentation to restrict SSH exposure; consider key-based authentication as an alternative.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm SSH service is accessible
    Scan the device network or check if TCP port 22 is listening and reachable
    Affected if SSH port 22 is open and exposed to an untrusted network
  2. Identify the ControlEdge PLC firmware version
    Access the device administrative interface or use manufacturer diagnostic tools to retrieve the firmware revision
    Affected if Firmware version is r151.2 or higher - NOT vulnerable; versions below r151.2 are affected
  3. Identify the ControlEdge RTU firmware version
    Access the device administrative interface or use manufacturer diagnostic tools to retrieve the firmware revision
    Affected if Firmware version is r151.2 or higher - NOT vulnerable; versions below r151.2 are affected
  4. Verify root SSH access configuration
    Check the SSH service configuration on the device to determine if root login is permitted
    Affected if Root login over SSH is enabled - required for the hardcoded credential exploitation to succeed

The device is affected if SSH port 22 is accessible and the firmware version is below r151.2, combined with root SSH login being enabled.

Mitigation

Replace hardcoded credentials with unique, strong passwords changed during commissioning; disable root SSH access if possible; implement network segmentation to restrict SSH exposure; consider key-based authentication as an alternative.

Recommended fix High confidence

Firmware r151.2

  1. Obtain the fixed firmware version r151.2 or later from the official Honeywell/Controledge support渠道
  2. Follow the vendor's documented firmware update procedure for ControlEdge PLC/RTU devices
  3. Verify the firmware version has been successfully updated to r151.2 or later
  4. After upgrading, immediately change the default root SSH credentials to unique, strong passwords
