CVE-2023-43208 분석

NextGen HealthCare의 오픈 소스 데이터 통합 크로스 플랫폼 Mirth Connect 솔루션에 의존하는 의료 서비스 제공자들은 새로운 RCE 취약점인 CVE-2023-43208.

로 추적되는 즉각적인 공개가 발생함에 따라 즉시 소프트웨어를 최신 버전으로 업데이트할 것을 강력히 추천합니다. 버전 4.4.1 이전의 모든 Mirth Connect 인스턴스는 드러난 보안 결함에 취약한 것으로 간주됩니다. 이 취약점은 CVSS 점수 9.8의 CVE-2023-37679로 알려진 Mirth Connect v4.3.0에 영향을 미치는 이전에 발견된 RCE 취약점에 대한 불완전한 패치의 결과입니다.

CVE-2023-43208은 시스템에 처음 접근하기 위해 적들에 의해 악용될 수 있으며, 이는 궁극적으로 중요한 의료 데이터의 손상으로 이어질 수 있습니다. Mirth Connect가 가장 흔히 배포되고 시스템 권한으로 실행되는 Windows 시스템에서는 CVE-2023-43208이 Windows 호스트에서 ping 명령을 실행하여 무기화될 수 있다고 Horizon3.ai 연구는 밝히고 있습니다. 아직 CVE-2023-43208에 대한 공개된 익스플로잇은 없으나, Java XStream에 기반한 악용 방법은 널리 알려져 있고 잘 문서화되어 있습니다. 사이버 보안 연구자들은 2015년 및 2016년의 Mirth Connect 버전도 손상 위험이 있는 것으로 보이기 때문에 보안 결함에 대한 추가 기술 정보를 공유하는 것을 삼가고 있습니다.

CVE-2023-43208의 악용 방법에 대한 널리 퍼진 지식 때문에 Mirth Connect를 버전 4.4.1로 업데이트하고 위험을 최소화하며 악용 시도를 적극적으로 탐지할 것을 강력히 권장합니다. CVE, 제로데이 및 모든 규모의 새로운 공격에 대한 최신 탐지 알고리즘 접근으로 모든 공격 캠페인에 앞서있으십시오. 위협 탐지 마켓플레이스 로부터의 접근을 통해 최신 탐지 알고리즘의 이점을 누리십시오.
