CVE-2025-4186
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, which was classified as critical, was found in Wangshen SecGate 3600 2024. Affected is an unknown function of the file /?g=route_ispinfo_export_save. The manipulation of the argument file_name leads to path traversal. It is possible to launch the attack remotely. 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 · moderate confidenceA path traversal vulnerability exists in Wangshen SecGate 3600 2024 firewall product. The vulnerable endpoint /?g=route_ispinfo_export_save does not properly validate the file_name parameter, allowing attackers to use '../' sequences to access arbitrary files on the system remotely. This could enable unauthorized access to sensitive configuration files, credentials, or other system files.

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.
-
Confirm Wangshen SecGate 3600 2024 is deployedReview your network infrastructure or asset inventory to identify if the Wangshen SecGate 3600 2024 firewall product is installed in your environment.Affected if The product is present in your environment.
-
Identify if the vulnerable endpoint is exposedCheck your firewall's web interface or reverse proxy configuration for accessibility to the path /?g=route_ispinfo_export_save. Attempt to access this endpoint via HTTP/HTTPS from an authorized position.Affected if The endpoint responds to requests (returns any HTTP status other than 404).
-
Locate the file_name parameterAnalyze HTTP requests to the endpoint /?g=route_ispinfo_export_save and identify the file_name parameter in the request (typically GET or POST).Affected if The file_name parameter exists and is accepted by the endpoint.
-
Test for path traversal acceptanceSubmit a request to the endpoint with file_name containing '../' sequences (for example: ../../../etc/passwd) and observe the response.Affected if The endpoint accepts and processes path traversal sequences without rejecting them.
You are affected if Wangshen SecGate 3600 2024 is deployed and the /?g=route_ispinfo_export_save endpoint with its file_name parameter accepts path traversal sequences like '../' to access files outside the intended directory.

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 file_name parameter to reject path traversal sequences (../) and restrict file operations to an allowed directory whitelist. Validate that the resolved path stays within the intended base directory.
