Oracle WebLogic - Remote Code Execution (CVE-2023-21839)

Oracle Weblogic is affected by a Remote Code Execution vulnerability inside the Core component.The root cause of this vulnerability is an insecure deserialization via T3, IIOP protocol that could allow an unauthenticated attacker to take control of the server. The attacker can send a crafted JNDI/RMI malicious object in order to achieve access to the server.

The risk exists that a remote unauthenticated attacker can fully compromise the server in order to steal confidential information, install ransomware, or pivot to the internal network.

Sniper can gain unauthenticated Remote Code Execution on the target system and extract multiple artefacts as evidence.

Upgrade the Oracle WebLogic to the latest version.
