As the CVSS score of 7.5 suggests, this is a critical issue that needs to be addressed immediately. Hackers can use it to launch ransomware or install backdoors without leaving a trace.

To protect yourself, make sure to apply the latest patches released by Oracle for all affected versions. Regularly monitor for new advisories and always keep your WebLogic installations up to date. Consider disabling unnecessary remote access ports and protocols when not in use.

Following basic security best practices can go a long way in preventing exploitation of such vulnerabilities. Take backups of critical data and keep a close watch for any suspicious activity on your servers. Staying on top of security updates is key to protecting your Oracle infrastructure from external threats.
