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
Techroutes TR 1803-3G Wireless Cellular Router/Modem 2.4.25 devices do not possess any protection against a CSRF vulnerability, as demonstrated by a goform/BasicSettings request to disable port filtering.

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 Techroutes TR 1803-3G Wireless Cellular Router with firmware 2.4.25 lacks CSRF (Cross-Site Request Forgery) protection in its web management interface. Attackers can exploit this by tricking authenticated administrators into visiting malicious pages, which then silently submit requests to the router's goform/BasicSettings endpoint to modify settings such as disabling port filtering.

MitigationSince this is a firmware-level vulnerability with no documented vendor patch available, mitigation requires either replacing the device with a model receiving security updates, or implementing network-level controls (like restricting web management access to trusted IP ranges/VPN) to reduce attack surface.

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 router model
    Check the device label or log into the web management interface to confirm the model is Techroutes TR 1803-3G
    Affected if The device is a Techroutes TR 1803-3G Wireless Cellular Router
  2. Check the firmware version
    Access the router's web UI (typically at 192.168.1.1 or similar) and navigate to Status or System Information page to find the firmware version
    Affected if The firmware version is exactly 2.4.25
  3. Verify web management interface is accessible
    Attempt to access the router's web interface over HTTP or HTTPS from a browser
    Affected if The web management interface is reachable on the network (even if behind NAT)
  4. Confirm the goform/BasicSettings endpoint exists
    Access the router's web UI and examine if there is a BasicSettings form under the goform path, or attempt a GET request to the endpoint
    Affected if The goform/BasicSettings endpoint exists and accepts configuration requests

The device is affected if it is a Techroutes TR 1803-3G router running firmware version 2.4.25 with its web management interface accessible on the network, as the CSRF protection is absent by design in this specific firmware version.

Mitigation

Since this is a firmware-level vulnerability with no documented vendor patch available, mitigation requires either replacing the device with a model receiving security updates, or implementing network-level controls (like restricting web management access to trusted IP ranges/VPN) to reduce attack surface.
