CVE-2020-14644 is a critical unauthenticated remote code execution vulnerability in Oracle WebLogic Server Core affecting supported versions 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0. Oracle states the issue is easily exploitable by an unauthenticated attacker with network access via the IIOP or T3 protocols. Supporting content indicates exploitation is performed by sending crafted serialized Java objects to a vulnerable WebLogic instance, resulting in unsafe deserialization and attacker-controlled command execution on the target host. The vulnerability has been publicly validated with payloads that trigger outbound DNS callbacks and execute OS commands on both Linux and Windows systems. Oracle assigned a CVSS 3.1 base score of 9.8, and the issue is included in CISA's Known Exploited Vulnerabilities Catalog.
