In Jboss Application Server as shipped with Red Hat Enterprise Application Platform 5.2, it was found that the doFilter method in the ReadOnlyAccessFilter of the HTTP Invoker does not restrict classes for which it performs deserialization and thus allowing an attacker to execute arbitrary code via crafted serialized data.
It was found that OpenSSL was vulnerable to a SSL/TLS MITM vulnerability. An attacker using a carefully crafted handshake can force the use of weak keying material in OpenSSL SSL/TLS clients and servers. This can be exploited by a Man-in-the-middle (MITM) attack where the attacker can decrypt and modify traffic from the attacked client and server.
As per the upstream advisory:
The attack can only be performed between a vulnerable client and server. OpenSSL clients are vulnerable in all versions of OpenSSL. Servers are only known to be vulnerable in OpenSSL 1.0.1 and 1.0.2-beta1. Users of OpenSSL servers earlier than 1.0.1 are advised to upgrade as a precaution.
OpenSSL 0.9.8 SSL/TLS users (client and/or server) should upgrade to 0.9.8za. OpenSSL 1.0.0 SSL/TLS users (client and/or server) should upgrade to 1.0.0m. OpenSSL 1.0.1 SSL/TLS users (client and/or server) should upgrade to 1.0.1h.

A flaw was found in JBoss Enterprise Application Platform. The processInvocation function within the org.jboss.as.ejb3.security.AuthorizationInterceptor component incorrectly authorizes all requests when no roles are defined for an Enterprise Java Beans (EJB) method invocation. This allows attackers to bypass intended access restrictions for EJB methods, leading to unauthorized access to sensitive functionalities.
The SecurityAssociation.getCredential method in JBoss Enterprise Application Platform (EAP) before 5.2.0, Web Platform (EWP) before 5.2.0, BRMS Platform before 5.3.1, and SOA Platform before 5.3.1 returns the credentials of the previous user when a security context is not provided, which allows remote attackers to gain privileges as other users.
The CallerIdentityLoginModule in JBoss Enterprise Application Platform (EAP) before 5.2.0, Web Platform (EWP) before 5.2.0, BRMS Platform before 5.3.1, and SOA Platform before 5.3.1 allows remote attackers to gain privileges of the previous user via a null password, which causes the previous user's password to be used.
It was found that the NonManagedConnectionFactory would log the username and password in cleartext when an exception was thrown. A local attacker could exploit this flaw by reading the password from the log file, if they had appropriate permissions to read the log file.
