How to fix?

Upgrade io.undertow:undertow-core to version 2.2.31.Final, 2.3.12.Final or higher.

Overview

io.undertow:undertow-core is a Java web server based on non-blocking IO.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling. An attacker can disrupt service availability by repeatedly sending AJP requests that exceed the configured max-header-size attribute in ajp-listener, leading to the server closing the TCP connection without returning an AJP response.

Note:

This is only exploitable if the max-header-size is set to 64 KB or less.
