## Description

Wangshen SecGate 3600 has been found to have a path traversal vulnerability affecting the processing of the file ?g=log_export_file. The manipulation of the argument file_name leads to path traversal, allowing attackers to read arbitrary files on the system.

## CrowdSec analysis

[CVE-2025-4078](https://euvd.enisa.europa.eu/vulnerability/CVE-2025-4078) is a path traversal vulnerability in Wangshen SecGate 3600 version 2400. The ?g=log_export_file endpoint fails to properly sanitize the file_name parameter, allowing authenticated attackers to use directory traversal sequences to read arbitrary files on the system, such as /etc/passwd.

CrowdSec has been tracking this vulnerability and its exploits since 18th of March 2026.

CrowdSec has not observed any significant exploitation activity targeting CVE-2025-4078 across its network. As a result, no community-driven trend analysis is available for this vulnerability at this time.

Attackers send a GET request to `/?g=log_export_file` with the `file_name` parameter set to a directory traversal payload such as `../../../../../../../etc/passwd` to read arbitrary system files.
