Synopsis

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

Description

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.

Solution

Apply the appropriate patch according to the April 2016 Oracle Critical Patch Update advisory.
