CVE-2025-25684
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 lack of validation in the path parameter (/download) of GL-INet Beryl AX GL-MT3000 v4.7.0 allows attackers to download arbitrary files from the device's file system via a crafted POST request.
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 confidenceThe GL-INet Beryl AX GL-MT3000 router firmware v4.7.0 contains a path traversal vulnerability in the /download endpoint. The path parameter in POST requests is not validated, allowing attackers to use directory traversal sequences (e.g., ../) to read arbitrary files from the device's filesystem.

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 device modelCheck the router label or access the admin interface and look for the model name (typically displayed on the status or system info page)Affected if The device is NOT a GL-INET Beryl AX GL-MT3000 router, then it is not affected by this specific CVE
-
Check the installed firmware versionAccess the router admin interface, navigate to System > Firmware or Status page, and note the firmware version number displayedAffected if The firmware version is v4.7.0; other versions may or may not be affected depending on whether the vulnerability was backported or introduced in a different version
-
Verify the /download endpoint is accessibleSend a POST request to the /download endpoint on the router's web interface (typically https://router-ip/cgi-bin/api/download or similar); check if the endpoint respondsAffected if The /download endpoint returns any response (success or error), indicating the vulnerable functionality is present and reachable
-
Test for path traversal vulnerabilitySend a POST request to /download with a path parameter containing traversal sequences such as ../../etc/passwd or ../../etc/config/wirelessAffected if The request returns contents of files outside the intended download directory, confirming the path traversal vulnerability is exploitable
You are affected if you have a GL-MT3000 router running firmware v4.7.0 with the /download endpoint accessible and responsive to path traversal sequences.

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 strict input validation on the path parameter to reject traversal sequences, restrict download functionality to whitelisted directories, and apply vendor firmware patch when available.
