Synopsis

Important: JBoss Enterprise Application Platform 6.0.1 security update

Type/Severity

Security Advisory Important

Topic

An update for JBoss Enterprise Application Platform 6.0.1 which fixes one security issue is now available from the Red Hat Customer Portal.

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.

Description

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 as provided from the Red Hat Customer Portal are advised to apply this update.

Solution

The References section of this erratum contains a download link (you must log in to download the update). Before applying this update, back up your existing JBoss Enterprise Application Platform installation and deployed applications.
