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.

Denial of Service: Parse Double

Java/JSP

Abstract

프로그램은 double을 구문 분석하고 스레드가 응답하지 않도록 만들 수 있는 메서드를 호출합니다.

Explanation

java.lang.Double.parseDouble() 및 [2^(-1022) - 2^(-1075) : 2^(-1022) - 2^(-1076)] 범위에 있는 임의의 수를 구문 분석할 때 스레드가 응답하지 않도록 만들 수 있는 관련된 메서드의 구현에 취약점이 있습니다. 이 결함은 DoS(Denial of Service) 공격을 실행하는 데 사용될 수 있습니다.

예제 1: 다음 코드는 취약한 메서드를 사용합니다.


Double d = Double.parseDouble(request.getParameter("d"));

매개 변수 d가 해당 범위의 값(예: "0.0222507385850720119e-00306")인 경우, 공격자가 요청을 보내 요청을 처리하는 동안 프로그램이 응답하지 않도록 만들 수 있습니다.

이 취약성은 Java 버전 6 업데이트 23 이하 버전에서 나타나며, Java 버전 6 업데이트 24 이상 버전에서는 나타나지 않습니다.
