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
All versions prior to ZSRV2 V3.00.40 of the ZTE ZXR10 1800-2S products allow remote authenticated users to bypass the original password authentication protection to change other user's password.

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 ZTE ZXR10 1800-2S router's web management interface contains an authentication bypass vulnerability in the password change functionality. Authenticated users can manipulate the password reset mechanism to change passwords of other users without proper authorization, enabling privilege escalation from standard user to administrator accounts.

MitigationUpgrade the device firmware to ZSRV2 V3.00.40 or later to obtain the vendor patch. If immediate upgrade is not feasible, limit web management interface access to trusted IP addresses only and monitor authentication logs for unauthorized password modification attempts.

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 router's web management interface or CLI and locate the system information page to confirm the device is a ZTE ZXR10 1800-2S. This is typically found under Status > System Info or via CLI command 'show system-info'.
    Affected if The device model matches ZTE ZXR10 1800-2S
  2. Check the installed firmware version
    In the web interface, navigate to Status > System Info or Administration > Firmware Upgrade to view the current firmware version. Alternatively, use CLI command 'show version' or 'show firmware-version' if telnet/SSH access is available.
    Affected if The firmware version is below 3.00.40 (for example, 3.00.30, 2.x.x, etc.)
  3. Verify web management interface is enabled
    Check if the HTTP/HTTPS web management interface is active by attempting to access the router's IP address in a browser (commonly http://192.168.1.1). Also verify via CLI using 'show ip http' or 'show web-service status'.
    Affected if The web management interface is accessible and enabled on the device
  4. Confirm multiple user accounts exist
    In the web interface, go to Administration > User Management or Administration > Account Settings to list all configured users. In CLI, use 'show users' or 'show accounting' commands.
    Affected if Two or more user accounts are configured on the device, providing potential targets for unauthorized password modification

The device is affected if it is a ZTE ZXR10 1800-2S router running firmware version below 3.00.40 with the web management interface enabled and multiple user accounts present.
