이 섹션에는 소스 코드 외부에 있지만 제작 중인 제품의 보안에는 여전히 중요한 내용이 모두 포함되어 있습니다. 이 섹션에서 다루는 문제들은 소스 코드와 직접적으로 관련이 없기 때문에 나머지 섹션과 분리했습니다.

Dockerfile Misconfiguration: Default User Privilege

Docker

Abstract

Dockerfile에 USER가 지정되어 있지 않으므로 기본적으로 루트 사용자로 실행됩니다.

Explanation

Dockerfile에 USER가 지정되어 있지 않으면 Docker 컨테이너는 기본적으로 슈퍼 사용자 권한으로 실행됩니다. 이러한 슈퍼 사용자 권한은 컨테이너 안에서 실행 중인 코드로 전파되며 필요 이상으로 많은 권한을 제공합니다. 슈퍼 사용자 권한으로 Docker 컨테이너를 실행하면 공격 표면이 확장되어 공격자가 더 심각한 형태의 악용을 감행할 수 있습니다.
