Oracle Weblogic - Remote Command Execution (CVE-2020-14883)

Oracle Weblogic is affected by a Remote Code Execution vulnerability in the Console component. This vulnerability was found because of the simultaneous vulnerability of the server to CVE-2020-14882 which makes CVE-2020-14883 possible. By exploiting the CVE-2020-14882 vulnerability, an attacker can bypass authentication of the console component and afterward send commands via an MVEL expression under the handle of com.tangosol.coherence.mvel2.sh.ShellSession class. This may potentially cause remote code execution, allowing a malicious unauthenticated attacker to execute arbitrary code on the server.

The risk exists that a remote unauthenticated attacker can fully compromise the Oracle Weblogic 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 server to the latest version.
