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
ControlEdge PLC (R130.2, R140, R150, and R151) and RTU (R101, R110, R140, R150, and R151) exposes unencrypted passwords on the network.

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 · moderate confidence

The ControlEdge PLC and RTU devices expose unencrypted passwords on the network, allowing an unauthenticated attacker with network access to intercept or sniff these credentials. This is a high-severity confidentiality issue affecting specific firmware revisions (R130.2, R140, R150, R151 for PLCs and R101, R110, R140, R150, R151 for RTUs).

MitigationImplement network segmentation and encrypted communications (VPNs) to protect PLC/RTU traffic. Check vendor for firmware updates addressing credential encryption, and change exposed passwords immediately after assessment.

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. Identify device model and firmware version
    Access the ControlEdge PLC or RTU device web interface, console, or management interface and locate the firmware version information. This is typically found under System Info, Device Status, or Firmware/About sections.
    Affected if The firmware version matches R130.2, R140, R150, or R151 for PLCs, or R101, R110, R140, R150, or R151 for RTUs.
  2. Capture network traffic on the PLC/RTU segment
    Use a network packet capture tool (such as Wireshark or tcpdump) on the network segment where the ControlEdge device communicates. Monitor traffic for plaintext credential transmission, especially during authentication or device communication events.
    Affected if Network captures show usernames and passwords transmitted in cleartext without encryption protocols such as TLS or SSH.
  3. Inspect communication protocols in use
    Review the device configuration and active services to determine which protocols are enabled for remote access and data transmission. Check for use of unencrypted protocols like HTTP, Telnet, or legacy industrial protocols without encryption wrappers.
    Affected if The device uses unencrypted protocols (HTTP, Telnet, unencrypted Modbus, etc.) for operator authentication or device management.
  4. Verify encryption status of management interfaces
    Attempt to access the device web interface and note whether the connection uses HTTPS with valid certificates or HTTP. Also check if VPN or encrypted tunnels are required for remote access.
    Affected if Management interfaces are accessible over unencrypted HTTP without requiring VPN or TLS encryption.

A user is affected if their ControlEdge PLC or RTU runs one of the listed firmware versions AND network captures or interface inspection reveals that authentication credentials are transmitted in plaintext without encryption.

Mitigation

Implement network segmentation and encrypted communications (VPNs) to protect PLC/RTU traffic. Check vendor for firmware updates addressing credential encryption, and change exposed passwords immediately after assessment.
