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.

Deserialization Bad Practice: Deny List

Java/JSP

Abstract

알려진 불량 클래스(거부 목록)의 역직렬화 방지에 기반한 방어적 역직렬화의 경우 공격자가 이 보호를 우회하여 무효화할 수 있습니다.

Explanation

응용 프로그램은 응용 프로그램이 실제로 역직렬화되기 전에 역직렬화된 클래스를 확인할 수 있도록 해주는 미리 보기 역직렬화라고 하는 방어적 역직렬화를 구현합니다.

거부 목록은 새로운 가젯 체인, 래핑된 패키지 또는 자체 역직렬화 콜백 내에서 중첩된 역직렬화를 수행하는 클래스에 의해 쉽게 우회될 수 있습니다.
