CVE-2024-3653

Undertow: learningpushhandler can lead to remote memory dos attacks

Description

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.

Remediation

Workaround:

  • Setting the maxAge configuration is sufficient to prevent the behavior of this vulnerability being explored.
