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
A vulnerability was found in Ruijie RG-NBS2009G-P up to 20240305. It has been classified as critical. Affected is an unknown function of the file /system/passwdManage.htm of the component Password Handler. The manipulation leads to improper authorization. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-257280. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

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

A critical authorization flaw exists in the password management component of Ruijie RG-NBS2009G-P switches in the /system/passwdManage.htm file. The vulnerability allows remote attackers to bypass proper authorization checks in the Password Handler, potentially enabling unauthorized password modifications or administrative access. The public disclosure indicates the issue was known but the vendor did not respond to early notification.

MitigationSince the vendor has not provided a patch, implement compensating controls: restrict web management interface access to trusted management networks via firewall rules, disable remote management if not required, monitor for suspicious access patterns to the password management interface, and consider device replacement if end-of-life.

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 the device model
    Access the switch CLI or web interface and retrieve the hardware model information. This is typically visible in the web interface header, system status page, or via CLI command like 'show version'
    Affected if The device is a Ruijie RG-NBS2009G-P switch
  2. Verify web management interface is enabled
    Check the switch configuration for web management access. In CLI, look for 'http server' or 'ip http server' commands. In the web interface, navigate to system settings or management options
    Affected if HTTP/HTTPS web management interface is enabled and accessible on the device
  3. Confirm the vulnerable endpoint exists
    Attempt to access the URL path /system/passwdManage.htm on the device's web interface. This may require authentication or may be accessible without proper authorization
    Affected if The /system/passwdManage.htm endpoint responds (returns HTTP 200 or any response) indicating the password management page exists on the device
  4. Check network accessibility of management interface
    Determine if the web management interface is exposed to untrusted networks. Review firewall rules, VLAN configuration, and management access control lists (ACLs) that control who can reach the device's IP on HTTP/HTTPS ports
    Affected if The web management interface is reachable from networks other than trusted management networks (for example, from the general network or internet)

If the device is a Ruijie RG-NBS2009G-P with the web management interface enabled and the /system/passwdManage.htm endpoint is accessible (with or without authentication), the device is affected by this authorization bypass vulnerability.

Mitigation

Since the vendor has not provided a patch, implement compensating controls: restrict web management interface access to trusted management networks via firewall rules, disable remote management if not required, monitor for suspicious access patterns to the password management interface, and consider device replacement if end-of-life.
