Red Hat Security Advisory: JBoss Enterprise Application Platform 6.0.1 security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2013:0231 Final 1 1 2013-02-04T23:28:00Z Current version 2013-02-04T23:28:00Z 2013-02-04T23:28:00Z Red Hat rhsa-to-cvrf 1.0.1484 2013-02-04T23:32:01Z Updated JBoss Enterprise Application Platform 6.0.1 packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. JBoss Enterprise Application Platform 6 is a platform for Java applications based on JBoss Application Server 7. When using LDAP authentication with either the "ldap" configuration entry or 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) Note: If you are using the "ldap" configuration entry and rely on empty passwords, they will no longer work after applying this update. The jboss-as-domain-management module, by default, will prevent empty passwords. This cannot be configured; however, a future release may add a configuration option to allow empty passwords when using the "ldap" configuration entry. Warning: Before applying this update, back up your existing JBoss Enterprise Application Platform installation and deployed applications. All users of JBoss Enterprise Application Platform 6.0.1 on Red Hat Enterprise Linux 5 and 6 are advised to upgrade to these updated packages. The JBoss server process must be restarted for the update to take effect. Please see https://www.redhat.com/footer/terms-of-use.html Copyright © 2013 Red Hat, Inc. All rights reserved.
