| 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. |
