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 i6 1.0.0.7(2204). Affected by this issue is the function R7WebsSecurityHandlerfunction of the component HTTP Handler. This manipulation causes path traversal. It is possible to initiate the attack remotely. 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

Path traversal vulnerability in Tenda i6 router's HTTP Handler component (R7WebsSecurityHandlerfunction) allows remote attackers to access unauthorized filesystem paths. With a 9.8 CVSS critical rating, this could enable unauthorized file access, configuration extraction, or further compromise of the device.

MitigationApply vendor firmware patch when available; otherwise restrict network exposure by disabling remote HTTP management or placing device behind a properly configured firewall.

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 Tenda i6 router on the network
    Access the router's web administration interface via its IP address, or use network scanning tools to identify the device model and MAC vendor information (Tenda). Check the device label or admin page for model confirmation.
    Affected if The device is a Tenda i6 router and the web interface is accessible.
  2. Check the firmware version
    Log into the router's web admin panel (typically at http://192.168.0.1 or similar) and navigate to System Settings or Status page to view the firmware version. Alternatively, use Nmap or curl to check HTTP response headers for version information.
    Affected if The firmware version displayed is exactly 1.0.0.7(2204).
  3. Confirm HTTP Handler is active
    Send an HTTP request to the router's IP address on ports 80 or 443 using curl or a browser. Verify that the web interface responds to HTTP requests.
    Affected if The router's web interface responds to HTTP requests, indicating the HTTP Handler component is active.
  4. Test for path traversal access
    Attempt to access a known file outside the web root by sending a crafted HTTP GET request with directory traversal sequences (e.g., ../../etc/passwd or ../../proc/version) to the router's HTTP handler endpoint. Use curl: curl -v "http://<router-ip>/../../etc/passwd"
    Affected if The HTTP handler returns content from files outside the expected web root directory, confirming the path traversal vulnerability is present.

The user is affected if they have a Tenda i6 router running firmware version 1.0.0.7(2204) with the HTTP interface accessible and the path traversal test successfully retrieves files outside the web root.
