Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-62221	JBOS-AS-000045	SV-76711r1_rule		High

Description
Silent Authentication is a configuration setting that allows local OS users access to the JBoss server and a wide range of operations without specifically authenticating on an individual user basis. By default $localuser is a Superuser. This introduces an integrity and availability vulnerability and violates best practice requirements regarding accountability.
