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
The Bently Nevada 3700 series of condition monitoring equipment through 2022-04-29 has a maintenance interface on port 4001/TCP with undocumented, hardcoded credentials. An attacker capable of connecting to this interface can thus trivially take over its functionality.

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

The Bently Nevada 3700 series condition monitoring equipment contains undocumented, hardcoded credentials for a maintenance interface accessible on port 4001/TCP. An attacker with network access to this port can authenticate using these credentials and gain full control of the device functionality.

MitigationImmediately restrict network access to port 4001/TCP using firewall rules or network segmentation to prevent unauthorized access. Contact Bently Nevada for firmware updates addressing the hardcoded credentials and implement compensating controls until a patch is available.

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 Bently Nevada 3700 series device on the network
    Perform a network scan to detect Bakerhughes Bently Nevada 3701/40, 3701/44, 3701/46, or 60m100 devices. Check device identification strings or MAC vendor information if available.
    Affected if The device is a Bently Nevada 3701/40, 3701/44, 3701/46, or 60m100 condition monitoring unit.
  2. Check if port 4001/TCP is exposed
    Perform a TCP port scan targeting port 4001 on the device IP address. Verify if the maintenance interface port is reachable from network segments that should not have administrative access.
    Affected if Port 4001/TCP is open and accessible from an untrusted network segment.
  3. Determine the firmware version
    Access the device web interface or administrative console if available, and retrieve the firmware version information. Compare the installed version against the affected ranges: 3701/40, 3701/44, 3701/46 versions below 4.1, or any version of 60m100.
    Affected if Firmware version is below 4.1 on 3701/40, 3701/44, or 3701/46, OR the device is a 60m100 on any firmware version.
  4. Verify hardcoded credential presence
    Attempt to authenticate to the maintenance interface on port 4001/TCP using the default administrative credentials or test for known hardcoded credential patterns documented in security advisories for this CVE.
    Affected if Authentication succeeds with undocumented or default credentials on the maintenance interface.

A user is affected if they have a Bently Nevada 3701/40, 3701/44, 3701/46 (firmware < 4.1), or 60m100 (any version) device with port 4001/TCP accessible from an untrusted network, as hardcoded credentials can be used to gain full device control.
