First published: Tue Apr 12 2016(Updated: )

Only the VirtualHost explicitly enabled by an administrator to receive service messages from worker nodes (Tomcat or EAP workers). Unless the administrator made a grave mistake in opening an unsecured mod_cluster management VirtualHost to the Internet without any authentication, it is impossible to exploit this bug from an untrusted client. Special set of mod_cluster management protocol HTTP method requests. One could pass a certain number of = symbols in sequence after a legitimate element and cause segfault.
