The remote Oracle WebLogic server is affected by a remote code execution vulnerability.


The remote Oracle WebLogic Server is affected by a remote code execution vulnerability in the Java Messaging Service subcomponent in the readExternal() function due to improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit this, via a crafted object payload, to bypass the ClassFilter.class blacklist and execute arbitrary Java code in the context of the WebLogic server.
