CVE-2024-3653
Undertow: learningpushhandler can lead to remote memory dos attacks
CVSS Score
5.3
EPSS Score
0.0%
EPSS Percentile
0th
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.
