JBoss Enterprise Application Platform is a platform for Java applications, which integrates the JBoss Application Server with JBoss Hibernate and JBoss Seam.
When using LDAP authentication with the provided LDAP login modules (LdapLoginModule/LdapExtLoginModule), empty passwords were allowed by default. An attacker could use this flaw to bypass intended authentication by providing an empty password for a valid username, as the LDAP server may recognize this as an 'unauthenticated authentication' (RFC 4513). This update sets the allowEmptyPasswords option for the LDAP login modules to false if the option is not already configured. (CVE-2012-5629)
Warning: Before applying this update, back up your existing JBoss Enterprise Application Platform installation (including all applications and configuration files).
All users of JBoss Enterprise Application Platform 4.3.0 CP10 on Red Hat Enterprise Linux 4 and 5 are advised to upgrade to these updated packages. The JBoss server process must be restarted for the update to take effect.
