Executive Summary
A critical vulnerability has been identified in nginx-ui, a web management interface for NGINX. The flaw allows attackers to restart, create, modify, and delete NGINX configuration files with near-maximum severity impact. Successful exploitation could enable remote code execution, service disruption, or complete compromise of the NGINX infrastructure. Organizations using nginx-ui should immediately apply available patches or implement compensating controls such as restricting administrative access, monitoring for unauthorized configuration changes, and segmenting affected systems from critical networks.
Summary
Attackers can abuse the near-maximum severity flaw in nginx-ui to restart, create, modify, and delete NGINX configuration files.
