Red Hat Security Advisory: JBoss Enterprise Web Platform 5.2.0 security update Security Advisory secalert@redhat.com Red Hat Security Response Team RHSA-2013:0233 Final 1 1 2013-02-04T23:32:00Z Current version 2013-02-04T23:32:00Z 2013-02-04T23:32:00Z Red Hat rhsa-to-cvrf 1.0.1484 2013-02-04T23:44:02Z An update for JBoss Enterprise Web Platform 5.2.0 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. The Enterprise Web Platform is a slimmed down profile of the JBoss Enterprise Application Platform intended for mid-size workloads with light and rich Java applications. 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 Web Platform installation (including all applications and configuration files). All users of JBoss Enterprise Web Platform 5.2.0 as provided from the Red Hat Customer Portal are advised to apply this update.
