前言

众所周知,很多订阅产品的管理页面中包含许多功能,如使用情况、数据、用户、访问等管理。

今天分享一个国外利用业务逻辑缺陷打破订阅时限限制的案例,废话不多说,让我们开始吧。

漏洞详情

白帽小哥偶然间发现了一个带有Authentication Domains用户管理的界面,正如下面所看到的,该界面用于创建身份验证域或重命名默认名称或更改内容:

于此同时白帽小哥还发现使用此界面可以订阅专业计划:

经过一番测试,白帽小哥最终发现绕过方法。

首先进入用户管理:

接着点击用户设置按钮:

然后更改此处的值并拦截请求:

通过该请求,可以发现使用了 graphql :

POST /graphql HTTP/2
Host: redacted.com
Cookie: xxxxxxxxxxxxx

通过修改以下参数:

"name":"DEFAULT" 修改为 "name":"BUG"
"provisioningType":"Manual", 修改为 "provisioningType":"SCIM"

而后发送请求后至 Auth Domain 界面:

可以看到,成功绕过订阅限制。
