Description
Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, an input validation vulnerability in the logrotate configuration allows an authenticated user to cause a complete Denial of Service (DoS). By submitting a negative integer for the rotation interval, the backend enters an infinite loop or an invalid state, rendering the web interface unresponsive. This issue has been patched in version 2.3.4.
