계: Input Validation and Representation

입력 검증 및 표현 문제는 메타 문자, 대체 인코딩 및 숫자 표현 때문에 발생합니다. 보안 문제는 입력을 신뢰하기 때문에 발생합니다. 문제로는 "Buffer Overflows", "Cross-Site Scripting" 공격, "SQL Injection", 그 외 여러 가지가 있습니다.

Dangerous File Injection

Abstract
공격자가 임의의 콘텐트가 있는 시스템에서 파일을 만들 수 있습니다.
Explanation
공격자가 임의의 콘텐트가 있는 서버의 파일 시스템에서 파일을 만들 수 있습니다. 생성된 파일은 파일에 삽입된 콘텐트 제어 기능에 따라 공격자가 추가 공격을 수행하기 위해 나중에 사용될 수 있습니다.

공격자가 파일 콘텐트를 제어할 수 있고 웹 서버에서 파일을 제공하는 경우 서버에서 원격으로 임의의 명령을 실행할 수 있는 악성 웹 셸을 삽입할 수 있습니다.

공격자가 파일 시스템에서 다른 파일 콘텐트로 파일을 만들 수 있는 경우 취약한 응용 프로그램의 권한을 사용하여 접근할 수 있는 파일 시스템에서 임의의 파일을 읽을 수 있습니다.
