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.

SAPUI5 Misconfiguration: Unsanitized Editor

JavaScript/TypeScript

Abstract

sanitizeValue를 false로 설정하면 삭제되지 않은 입력이 Cross-Site Scripting과 같은 취약점으로 이어질 수 있습니다.

Explanation

sanitizeValue 속성은 값이 HTML 마크업에 적용될 때 HTML 삭제기를 실행할 것인지 여부를 결정합니다. 입력은 사용자로부터 직접 수신될 수 있으므로 안전하지 않은 것으로 간주될 수 있습니다. sanitizeValue 속성은 추가 입력 문자를 허용하는 등 여러 가지 이유로 인해 false로 설정될 수 있습니다. 하지만 이렇게 하면 안전하지 않은 사용자 입력이 코드에서 부주의로 실행될 수 있습니다. sanitizeValue 속성을 기본값인 true로 설정하는 것이 안전합니다.

예제 1: 다음은 SAPUI5 RichTextEditor에서 sanitizeValue 속성을 false로 설정합니다.


new RichTextEditor({
    sanitizeValue: false,
    value: input
}).placeAt("moreContent");
