Oracle Director of Security Assurance Eric Maurice, said that “they have recently received reports of attempts to maliciously exploit several recently-patched vulnerabilities, including vulnerability CVE-2020-2883, which affects multiple versions of Oracle WebLogic Server.”

The vulnerability can be abused by attackers to crack corporate networks and install malware.

The critical patch update for April 2020, which includes 405 new security updates, is highly recommended by Oracle.
