## Description

A flaw was found in wildfly-core. A remote user authenticated as an administrative user can inject a malformed payload into the Inet Address field through the Management Model. This injection causes the server to crash and become unrecoverable, as the payload is written into the standalone.xml configuration file. Manual intervention is required to restore server operation, leading to a denial of service.
