界: Input Validation and Representation

输入验证与表示问题是由元字符、交替编码和数字表示引起的。安全问题源于信任输入。这些问题包括：“Buffer Overflows”、“Cross-Site Scripting”攻击、“SQL Injection”等其他问题。

Handlebars Misconfiguration: Prototypes Allowed

JavaScript/TypeScript

Abstract

Handlebars 模板中允许使用原型，这容易受到 Prototype Pollution 漏洞的攻击。

Explanation

Handlebars 模板无法访问对象的原型，因为它使应用程序容易受到 Prototype Pollution 漏洞的攻击。

当恶意用户可以控制对象原型上的功能或属性时，就会发生 Prototype Pollution 攻击。控制传递到模板中的对象的原型会导致许多漏洞，包括 Dynamic Code Evaluation、Cross-Site Scripting 和 Remote Code Execution。

示例 1：在以下示例 Handlebars 模板配置中，默认情况下允许使用原型方法，以及特殊的 __defineGetter__ 函数。


let template2 = Handlebars.compile('{{foo}}')
console.log(template2({ foo: argument }, {
    allowProtoMethodsByDefault: true,
    allowedProtoMethods: {
        __defineGetter__: true
    }
}))
