Open Access Management（OpenAM）是一种访问管理解决方案。在 16.1.1 版本之前，默认配置下，iPlanetDirectoryPro SSO Cookie 初始化时未启用 HttpOnly，且未设置保护性的 SameSite 默认值；同时，OAuth 和 OpenID Connect 的同意流程通过 CsrfProtection 机制复用该 Cookie 作为 CSRF 令牌。当与同源跨站脚本攻击（XSS）相结合，且用户点击了攻击者控制的链接时，该 Cookie 可被读取并复用，从而窃

Vulnerability Title
OpenAM Insecure SSO Cookie Initialization
Source: CVE Program / CVE List V5
Vulnerability Description
Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, the default configuration initializes the iPlanetDirectoryPro SSO cookie with HttpOnly disabled and without a protective SameSite default, and OAuth and OpenID Connect consent flows reuse that cookie through CsrfProtection as a CSRF token. When combined with same-origin cross-site scripting and a user following an attacker-controlled link, the cookie can be read and reused to steal the SSO session and complete attacker-driven consent grants. This issue is fixed in version 16.1.1.
