Improper Authentication

This affects all versions of package react-adal. It is possible for a specially crafted JWT token and request URL can cause the nonce, session and refresh values to be incorrectly validated, causing the application to treat an attacker-generated JWT token as authentic. The logical defect is caused by how the nonce, session and refresh values are stored in the browser local storage or session storage. Each key is automatically appended by ||. When the received nonce and session keys are generated, the list of values is stored in the browser storage, separated by ||, with || always appended to the end of the list. Since || will always be the last 2 characters of the stored values, an empty string ("") will always be in the list of the valid values. Therefore, if an empty session parameter is provided in the callback URL, and a specially-crafted JWT token contains an nonce value of "" (empty string), then adal.js will consider the JWT token as authentic.

Salvoravida React-adal 授权问题漏洞

Salvoravida React-adal是Salvoravida个人开发者的一款基于JS语言的用于与Azure Active Directory交互的代码库。 react-adal 存在授权问题漏洞，该漏洞源于对于特殊设计的JWT令牌和请求URL，可能会导致nonce、会话和刷新值验证不正确，从而导致应用程序将攻击者可利用该漏洞生成的JWT令牌视为真实的。该逻辑缺陷是由nonce、会话和刷新值存储在浏览器本地存储或会话存储中的方式造成的。每个键被自动附加到||中。
