계: API Abuse
API는 호출자와 피호출자 간의 계약입니다. 가장 흔한 형태의 API 오용은 호출자가 이 계약에서 자신의 몫을 이행하지 못하기 때문에 발생합니다. 예를 들어, 프로그램이 chroot()를 호출한 후 chdir()을 호출하지 못하면 활성 루트 디렉터리를 안전하게 변경하는 방법을 지정하는 계약을 위반하는 것입니다. 라이브러리 오용의 또 다른 좋은 예는 피호출자가 호출자에게 신뢰할 만한 DNS 정보를 반환할 것으로 예상하는 것입니다. 이 경우, 호출자는 자신의 행동에 대해 특정한 가정을 함으로써(반환 값이 인증 목적으로 사용될 것으로 예상) 피호출자 API를 오용합니다. 다른 쪽에서 호출자-피호출자 계약을 위반할 수도 있습니다. 예를 들어, 코더가 하위 클래스 SecureRandom을 지정하고 임의 값이 아닌 값을 반환하는 경우 계약을 위반하는 것입니다.
ASP.NET MVC Bad Practices: Controller Action Not Restricted to POST
Abstract
이 컨트롤러 작업은 다음 HTTP 동사 중 하나만 수락하도록 제한하는 것이 좋을 수 있습니다. Post, Put, Patch 또는 Delete.
Explanation
쓰기, 업데이트 또는 삭제를 통해 데이터를 수정하는 ASP.NET MVC 컨트롤러 작업은 다음 HTTP 동사 중 하나만 수락하도록 제한하는 것이 좋을 수 있습니다. Post, Put, Patch 또는 Delete. 이렇게 하면 실수로 링크를 클릭해도 작업이 실행되지 않으므로 교차 사이트 요청 위조가 어려워집니다.
다음 컨트롤러 작업은 기본적으로 모든 verb를 허용하므로 cross-site request forgery에 취약할 수 있습니다.
