Detectify checks for critical Oracle WebLogic Server RCEs (CVE-2020-14882, CVE-2020-14750)

December 3, 2020

On October 29th, Detectify released a security test to detect a critical Oracle WebLogic Server RCE – CVE-2020-14882. Again in November, Oracle released an out-of-band security patch to fix a related RCE for Oracle Fusion Middleware. These vulnerabilities are currently being exploited by multiple botnets in the wild. Detectify scans your application for both of these vulnerabilities and will alert you if you are running a vulnerable version of Oracle WebLogic Server.

What can happen if I’m vulnerable?

The issue involves two remote code execution (CVE-2020-14882, CVE-2020-14750) vulnerabilities that allows attackers to execute arbitrary commands on unpatched Oracle WebLogic servers, enabling malicious actors to download files, log keystrokes, steal sensitive data, move laterally across a network, and even recruit compromised machines to a botnet and deploy crypto miners. The vulnerabilities can be exploited by simply sending one request to the server, which is why they have been assigned high severity scores.

Who is affected by this vulnerability?

Unpatched Oracle WebLogic servers and enterprise Java applications running on the platform.
