CWEhttps://cwe.mitre.org/data/definitions/400.html

A flaw was found in Undertow when using Remoting as shipped in Red Hat Jboss EAP before version 7.2.4. A memory leak in HttpOpenListener due to holding remote connections indefinitely may lead to denial of service. Versions before undertow 2.0.25.SP1 and jboss-remoting 5.0.14.SP1 are believed to be vulnerable.

Weakness

The product does not properly control the allocation and maintenance of a limited resource.

Potential Mitigations

  • Mitigation of resource exhaustion attacks requires that the target system either:

  • The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.

  • The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
