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.

Process Control: Invoker Servlet

Java/JSP

Abstract

InvokerServlet 클래스를 사용하면 공격자가 서버에서 모든 클래스를 호출할 수 있습니다.

Explanation

사용이 금지된 InvokerServlet 클래스는 서버의 가상 시스템에 사용할 수 있는 모든 클래스를 호출하는 데 사용할 수 있습니다. 정규화된 클래스 이름을 추측하여 공격자가 Servlet 클래스뿐만 아니라 POJO 클래스 또는 JVM에 사용 가능한 기타 클래스를 로드할 수 있습니다.
