Synopsis

Description

The remote Oracle WebLogic server is affected by a remote code execution vulnerability in the WLS Security component due to unsafe deserialize calls of unauthenticated Java objects to the Apache Commons File Upload library. An unauthenticated, remote attacker can exploit this, via a crafted a DiskFileItem object, to execute arbitrary code in the context of the WebLogic server.
