A Server-Side Request Forgery vulnerability in Nginx-UI allows authenticated attackers to perform unauthorized requests, compromising internal network security.

The vulnerability (CWE-918) allows an authenticated attacker to perform SSRF attacks by manipulating requests handled by the user interface. This enables the attacker to interact with internal services that are not typically exposed to the public network.

Exploitation of this SSRF vulnerability could allow an attacker to bypass firewalls and access internal infrastructure, leading to unauthorized data access or reconnaissance. With a CVSS score of 8.5, the risk is high, particularly in environments where Nginx-UI is deployed with elevated privileges or access to internal network segments.

Immediate Action: Monitor the vendor repository for the release of a patched version; currently, no direct patch is available for version 2.3.4.

Proactive Monitoring: Review web server and application logs for unusual outbound requests originating from the Nginx-UI server to internal IP addresses or restricted ports.

Compensating Controls: Deploy a Web Application Firewall (WAF) to filter and block suspicious outbound requests and restrict access to the Nginx-UI management interface to trusted IP ranges only.

Public Exploit Available: No (exploit_available: false)

Because no official patch is available, administrators must implement compensating network controls and limit access to the Nginx-UI interface immediately. Monitor for vendor updates daily and apply the fix as soon as it becomes available.
