Oracle Weblogic - Remote Code Execution (CVE-2018-2894)

Oracle Weblogic is affected by a Remote Code Execution vulnerability. This vulnerability is affecting the WLS subcomponent because the path of /ws_utc/config.do is reachable without authentication, meaning that the Weblogic server is in the development mode. The attacker can set a new Work Home Directory which needs to be writable and then upload JKS Keystores, which are Java Server Pages (JSP) files. Uploading a webshell as a JKS, the attacker can successfully achieve Remote Code Execution on the server.

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

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.

Upgrade the Oracle Weblogic to the latest version.
