#
# Vuln: lines 15-23 in core/lib/router.php
#---------- sof
# //Get page request (if any)
# $page = $this->getInputString("page", "index");
#
# //Get plugin request (if any)
# $plugin = $this->getInputString("system", "Page");
#
# //If there is a request for a plugin
# if(file_exists("core/plugs/".$plugin."Starter.php")){

#
# Additionally, the CMS allows an attacker to comment on blog posts which inturn will
# write a file on the remote disk with possibly 'malicious' content inside.
#
# exploit includes:
# - Proxy support
# - Dynamic User-agent generation
# - Apache access log and Lotus blog comment injection routines
# - Custom shell creation and deletion
#
# Environment:
# Apache 2.2.14/PHP 5.3.2
# php.ini -> magic_quotes_gpc = Off
#
# Example:
# [mr_me@pluto lotuscms]$ python luckylotus.py -c -i 1294585604 -p localhost:8080 -t 192.168.56.101 -d /webapps/lotus/lcms/
