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.
Handlebars Misconfiguration: Escaping Disabled
Abstract
Handlebars 템플릿에서 이스케이프가 처리가 비활성화되어 여러 가지 새로운 취약점이 발생할 수 있습니다.
Explanation
Handlebars 템플릿에서 수행되는 기본 이스케이프 처리는 공격자로부터 응용 프로그램을 보호하는 데 도움이 됩니다. 이렇게 하면 다양한 유형의 취약성에서 많은 공격 벡터를 방지할 수 있습니다. 가장 두드러진 기능은 특정 유형의 Cross-Site Scripting 공격으로부터 보호하는 것입니다. 이 응용 프로그램에서는 이 보호 메커니즘이 비활성화되어 있습니다.
예제 1: 다음 예제는 이스케이프 처리가 비활성화되어 있는 Handlebars 템플릿을 보여줍니다.
예제 1: 다음 예제는 이스케이프 처리가 비활성화되어 있는 Handlebars 템플릿을 보여줍니다.
let template = Handlebars.compile('{{foo}}', { noEscape: true })
