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.
JSON Path Manipulation
Abstract
이 응용 프로그램은 신뢰할 수 없는 데이터가 포함된 JSON 쿼리를 수행합니다. 따라서 공격자가 JSON 문서의 예기치 않은 부분을 쿼리하는 것이 가능할 수 있습니다.
Explanation
트리형 액세스 구문을 사용하여 JSON 문서를 조작할 수 있는 다양한 기술이 있습니다. 공격자는 이러한 유형의 문서 탐색을 사용하여 액세스해서는 안 되는 JSON 문서의 일부를 쿼리할 수 있습니다.
예제 1: 다음 코드는 사용자가 정의한 키워드를 사용하여 이름 및 주소 같은 공개 사용자 세부 정보가 포함된 JSON 문서에 액세스합니다. 그러나 이 JSON 문서에는 사용자 비밀번호 같은 개인 정보도 포함되어 있습니다.

$userInput = getUserIn();
$document = getJSONDoc();
$part = simdjson_key_value($document, $userInput);
