Acegi Misconfiguration: Run-As Authentication Replacement

Java/JSP

Abstract

在 Acegi 中使用 Run-As 身份验证替换功能可能引发权限提升漏洞。

Explanation

Acegi Security 允许在安全对象回调阶段临时替换 SecurityContext 中的身份验证对象。仅当 AuthenticationManager 和 AccessDecisionManager 成功处理原始身份验证对象时才会发生这种情况。RunAsManager 创建此身份验证对象。
通常，方法调用期间，开发人员使用 RunAsManager 为通过身份验证的用户配置一个或多个额外角色。此方法适用于需要访问远程应用程序的安全 Bean。由于远程应用程序可能需要不同的凭据，因而可以在调用角色与远程应用程序所需的角色之间进行转换，以便成功实施远程访问。直接接受新 Authentication 对象（称为 RunAsUserToken）作为有效 Authentication 对象，无需任何进一步的身份验证或授权检查。
为新 Authentication 对象新增角色或权限可暂时提升用户权限，允许用户采取未经授权的操作。
以下配置展示了使用 RunAsManager 针对角色为“ROLE_PEON”的用户添加角色“UBER_BOSS”，从而暂时提升此用户的权限，使其具备管理员权限，确保所有人员都能从 PrivateCatalog 中获取数据。
