    What to do

    Generated by Wavense from the CVE record — an immediate mitigation and the permanent fix.

    1. !

      Mitigate now

      Immediately restrict network access to the WebLogic console to only trusted IP addresses or internal management networks, ideally through a VPN. If the console is not actively used for administration, consider disabling it or placing it behind a strong authentication proxy. Implement enhanced logging and monitoring for any unauthenticated access attempts or unusual activity patterns on WebLogic server ports.

    2. ✓

      Permanent fix

      Apply the vendor-provided security patches from Oracle's Critical Patch Update (CPU) that specifically address CVE-2020-14750. Affected versions, including 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0, must be upgraded or patched immediately. Consult Oracle's official security advisories for the exact patch bundles and upgrade instructions relevant to your specific WebLogic Server version.

    Technical details— weakness, CVSS vector & calculator, related CVEs

    Business impact

    An unauthenticated attacker can remotely compromise the Oracle WebLogic Server via HTTP, gaining complete control over the system. This results in full confidentiality, integrity, and availability impacts, allowing for data exfiltration, service disruption, and arbitrary code execution. Such a takeover can lead to severe operational disruption, reputational damage, and potential regulatory non-compliance.

    CVE-2022-22965KEV⚙ WeaponizedExploit likely

    A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding. The specific exploit requires the application to run on Tomcat as a WAR deployment. If the application is deployed as a Spring Boot executable jar, i.e. the default, it is not vulnerable to the exploit. However, the nature of the vulnerability is more general, and there may be other ways to exploit it.
