CVE-2025-15371
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 · uneditedA vulnerability has been found in Tenda i24, 4G03 Pro, 4G05, 4G08, G0-8G-PoE, Nova MW5G and TEG5328F up to 65.10.15.6. Affected is an unknown function of the component Shadow File. Such manipulation with the input Fireitup leads to hard-coded credentials. An attack has to be approached locally. The exploit has been disclosed to the public and may be used.
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 confidenceHard-coded credentials vulnerability in the Shadow File component of multiple Tenda router models (i24, 4G03 Pro, 4G05, 4G08, G0-8G-PoE, Nova MW5G, TEG5328F) up to firmware version 65.10.15.6. The vulnerability allows local attackers to access the device using pre-configured credentials embedded in the firmware.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the router modelAccess the router web interface or check the physical device label to confirm the exact model (i24, 4G03 Pro, 4G05, 4G08, G0-8G-PoE, Nova MW5G, or TEG5328F)Affected if The device is one of the listed affected models and is accessible on the local network
-
Check the firmware versionLog into the router admin panel and navigate to System Settings, Status, or Firmware Upgrade page to find the installed firmware version; alternatively, check the Tenda support site for your modelAffected if The firmware version is 65.10.15.6 or lower (any version up to and including this release)
-
Access the shadow file if possibleIf you have shell access (via Telnet, SSH, or serial console), inspect /etc/shadow to review user accounts; if you have the firmware image, extract and analyze it for the shadow fileAffected if The shadow file contains user accounts that were not created by the administrator or that differ from the standard admin configuration
You are affected if your device is one of the listed Tenda models running firmware version 65.10.15.6 or lower, and the shadow file contains hard-coded credentials that were not explicitly configured.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement network segmentation to limit local access to affected devices; contact Tenda for firmware patches; consider replacing EOL devices that will not receive updates; disable unused services and enforce strong authentication where possible.
