Summary
A vulnerability was found in Undertow. This issue requires enabling the learning-push handler in the server's config, which is disabled by default, leaving the maxAge config in the handler unconfigured.
The default is -1, which makes the handler vulnerable. If someone overwrites that config, the server is not subject to the attack.
The attacker needs to be able to reach the server with a normal HTTP request.
