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 leftover debug code vulnerability exists in the httpd debug credentials functionality of Yifan YF325 v1.0_20221108. A specially crafted network request can lead to authentication bypass. An attacker can send a network request to trigger this vulnerability.

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 debug code vulnerability exists in the Yifan YF325 v1.0_20221108 httpd service where leftover debug credentials functionality allows authentication bypass. An attacker can send specially crafted network requests to bypass authentication mechanisms.

MitigationApply vendor firmware update if available; otherwise, network segment the device and restrict access to httpd service.

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
    Locate the device label, web interface, or SNMP/SSH banner that displays the hardware model. Common locations: physical device sticker, router admin page header, or network discovery response.
    Affected if The device is not a Yifan YF325 - if different model, this CVE does not apply.
  2. Determine the firmware version
    Access the device admin interface (typically via HTTP/HTTPS on LAN) and navigate to System Settings, Status, or About page. Alternatively, check the bootloader banner via serial console or the WISPR/UPnP response if available.
    Affected if Firmware version is NOT exactly 1.0_20221108 - only this specific version is listed as affected. Other versions may have different vulnerability status.
  3. Verify httpd service is network accessible
    Check if the device HTTP service is exposed to untrusted networks. Use nmap, netcat, or curl to test connectivity to ports 80/443 from external interfaces. Review port forwarding, firewall rules, and WAN/LAN configuration.
    Affected if The httpd service is directly exposed to untrusted networks (WAN/internet) - the bypass requires sending network requests to the service.
  4. Inspect for debug authentication endpoints
    Review the device web interface for hidden or undocumented endpoints, debug modes, or backdoor paths. Common indicators: unusual URLs, debug parameter in forms, or responses containing 'debug', 'test', or 'backdoor' strings.
    Affected if Debug functionality or undocumented authentication endpoints exist and are accessible - this is the specific feature that enables the bypass.

You are affected if you have a Yifan YF325 device running firmware version 1.0_20221108 with the httpd service network-accessible and debug authentication functionality present.
