Multiple SQL injection vulnerabilities in CRM/Core/Page/AJAX/Location.php in CiviCRM before 4.2.12, 4.3.x before 4.3.7, and 4.4.x before 4.4.beta4 allow remote attackers to execute arbitrary SQL commands via the _value parameter to (1) ajax/jqState or (2) ajax/jqcounty.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
