  • # 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:
