Executive brief
WildFly Core is a widely-used Java application server management framework. An authenticated administrative user can inject a malformed network address value into the server's configuration through the management interface, causing the server to crash and become unable to recover without manual intervention. This results in service unavailability and requires system administrators to manually restore configuration files.
Technical details
The vulnerability exists in WildFly Core's Management Model and allows injection of malformed payloads into the Inet Address field. An attacker with administrative credentials can craft a malicious payload that is persisted to the standalone.xml configuration file, triggering a server crash upon startup or during operation. The vulnerability requires authentication as an administrative user (precondition: valid admin credentials) and network access to the management interface. Successful exploitation causes denial of service by rendering the server unrecoverable without manual intervention to restore the configuration file. No patch information is currently available in the advisory.
