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.

Struts: Form Does Not Extend Validation Class

Java/JSP

Abstract

모든 Struts Form은 Validator 클래스를 확장해야 합니다.

Explanation

Struts 유효성 검사기를 사용하려면 폼이 다음 중 하나를 확장해야 합니다.


ValidatorForm
ValidatorActionForm
DynaValidatorActionForm
DynaValidaorForm

Struts 유효성 검사기는 이러한 클래스에서 validate() 메서드를 구현하여 응용 프로그램에 연결되므로 이러한 클래스 중 하나를 확장해야 합니다.

다음 클래스에서 파행된 폼은 Struts 유효성 검사기를 사용할 수 없습니다.


ActionForm
DynaActionForm

폼에 대한 검증 프레임워크를 우회하면 응용 프로그램이 다양한 유형의 공격에 노출됩니다. 확인되지 않은 입력은 Cross-Site Scripting, Process Control 및 SQL Injection과 같은 취약점의 원인이 됩니다. J2EE 응용 프로그램은 보통 메모리 손상 공격에는 취약하지 않지만 J2EE 응용 프로그램이 배열 범위 검사를 수행하지 않는 네이티브 코드와 상호 작용하는 경우, 공격자가 J2EE 응용 프로그램의 입력값 검증 실수를 이용하여 버퍼 오버플로 공격을 시작할 수 있습니다.
