REDHAT-BUG-2274437
First published: Thu Apr 11 2024(Updated: )
A vulnerability was found in Undertow. This vulnerability requires enabling the learning-push handler in the server's config (it is disabled by default), leave the maxAge config in the handler unconfigured. The default is -1, so it 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.
