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 determined in Tenda F451 1.0.0.7. This affects the function fromP2pListFilter of the file /goform/P2pListFilter. This manipulation of the argument page causes stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit has been publicly disclosed and may be utilized.

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 stack-based buffer overflow vulnerability exists in the Tenda F451 router firmware (version 1.0.0.7) within the /goform/P2pListFilter endpoint. The 'page' parameter passed to the fromP2pListFilter function is not properly bounds-checked before being copied to a stack-allocated buffer, allowing an attacker to overflow the buffer and potentially execute arbitrary code remotely.

MitigationApply available firmware updates from Tenda; if no patch exists, restrict access to the router's web management interface to trusted networks only and consider disabling the P2pListFilter feature until a fix 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 router model
    Access the router's web interface or check the device label to confirm the model is Tenda F451
    Affected if Device is not a Tenda F451 router - different models are not affected by this specific CVE
  2. Check firmware version
    Log into the router admin panel and navigate to System Settings > Firmware Upgrade, or use the router's web API to query the firmware version. The version is typically displayed on the status page or in the system info endpoint.
    Affected if Firmware version is not 1.0.0.7 - only this exact version is affected
  3. Verify P2pListFilter feature is accessible
    Attempt to access the /goform/P2pListFilter endpoint via HTTP GET or POST request. This can be done by sending a request to http://[router-ip]/goform/P2pListFilter
    Affected if The endpoint returns a valid response (even if error) - this indicates the vulnerable code path exists and is reachable
  4. Confirm P2pListFilter is enabled
    Check router admin panel for P2pListFilter or P2P filtering settings under Security or Access Control menus. If the feature can be disabled, verify its current state.
    Affected if P2pListFilter feature is enabled and the endpoint responds to requests with the 'page' parameter

You are affected if you have a Tenda F451 router running firmware version 1.0.0.7 with the P2pListFilter feature enabled and the /goform/P2pListFilter endpoint accessible.
