The (1) JNDI service, (2) HA-JNDI service, and (3) HAJNDIFactory invoker servlet in JBoss Enterprise Application Platform 4.3.0 CP10 and 5.1.2, Web Platform 5.1.2, SOA Platform 4.2.0.CP05 and 4.3.0.CP05, Portal Platform 4.3 CP07 and 5.2.x before 5.2.2, and BRMS Platform before 5.3.0 do not properly restrict write access, which allows remote attackers to add, delete, or modify items in a JNDI tree via unspecified vectors.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:1027 advisory.

    JBoss Application Server is the base package for JBoss Enterprise Web     Platform, providing the core server components. The Java Naming and     Directory Interface (JNDI) Java API allows Java software clients to locate     objects or services in an application server. The Java Authorization     Contract for Containers (Java ACC) specification defines Permission classes     and the binding of container access decisions to operations on instances of     these permission classes. JaccAuthorizationRealm performs authorization     based on Java ACC permissions and a Policy implementation.

    It was found that the JBoss JNDI service allowed unauthenticated, remote     write access by default. The JNDI and HA-JNDI services, and the     HAJNDIFactory invoker servlet were all affected. A remote attacker able to     access the JNDI service (port 1099), HA-JNDI service (port 1100), or the     HAJNDIFactory invoker servlet on a JBoss server could use this flaw to add,     delete, and modify items in the JNDI tree. This could have various,     application-specific impacts. (CVE-2011-4605)

    When a JBoss server is configured to use JaccAuthorizationRealm, the     WebPermissionMapping class creates permissions that are not checked and can     permit access to users without checking their roles. If the     ignoreBaseDecision property is set to true on JBossWebRealm, the web     authorization process is handled exclusively by JBossAuthorizationEngine,     without any input from JBoss Web. This allows any valid user to access an     application, without needing to be assigned the role specified in the     application's web.xml security-constraint tag. (CVE-2012-1167)

    Red Hat would like to thank Christian Schlter (VIADA) for reporting     CVE-2011-4605.

    Warning: Before applying this update, back up your JBoss Enterprise Web     Platform's server/[PROFILE]/deploy/ directory and any other customized     configuration files.

    Users of JBoss Enterprise Web Platform 5.1.2 on Red Hat Enterprise Linux 4,     5, and 6 should upgrade to these updated packages, which correct these     issues. The JBoss server process must be restarted for this update to take     effect.
