and 6.

important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each

Description

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java
applications based on JBoss Application Server 7.

A flaw was discovered in the way authenticated connections were cached on
the server by remote-naming. After a user has successfully logged in, a
remote attacker could use a remoting client to log in as that user without
knowing their password, allowing them to access data and perform actions
with the privileges of that user. (CVE-2013-4128)

A flaw was discovered in the way connections for remote EJB invocations via
the EJB client API were cached on the server. After a user has successfully
logged in, a remote attacker could use an EJB client to log in as that user
without knowing their password, allowing them to access data and perform
actions with the privileges of that user. (CVE-2013-4213)

These issues were discovered by Wolf-Dieter Fink of the Red Hat GSS Team.

Warning: Before applying this update, back up your existing Red Hat JBoss
Enterprise Application Platform installation and deployed applications.

All users of Red Hat JBoss Enterprise Application Platform 6.1.0 on Red Hat
