最近网上公开了一些瑞友天翼应用虚拟化系统的 SQL 注入漏洞，经过挖掘发现，还存在一些后台 SQL 注入漏洞。
重点关注传入参数可控并且拼接到 SQL 语句中的代码。
getappicon
首先检测了登录状态，然后将通过 GET 获取到的参数 id 直接拼接到 SQL 语句中。
GET /hmrao.php?s=/Admin/getappicon/&id=1');SELECT+SLEEP(5)+AND('1 HTTP/1.1

我们打印出执行的 SQL 语句，发现成功闭合 SQL。

useredit
首先检测了登录状态，然后将通过 GET 获取到的参数 id 直接拼接到 SQL 语句中。

我们看到这里检测登录状态的函数是 adminchecklogin
这里进行检测时会根据路由 sessId 来进行检测，所有需要将cookie 拼接在路由器上。

appedit
首先检测了登录状态，然后将通过 GET 获取到的参数 id 直接拼接到 SQL 语句中。
这里检测登录状态的函数同样也是 adminchecklogin
所以也需要将cookie 拼接在路由中。
