CVE-2020-2551: Unauthenticated Remote Code Execution in IIOP protocol via Malicious JNDI Lookup

Using the WebLogic libraries, it is possible to create a payload that causes a remote IIOP server to initialize a Java object that invokes a JNDI lookup to an attacker-controlled server, leading to code execution.
