The above SQL injection exist in the forms_fields_rules/rules page due to lack of filtering applied on the specific parameter. Below is the source code which shows the SQL vulnerability injection: at line 72 the unsanitized id is used as part of select query.

56 case ‘get_fields_choices’:
 58                 if(isset($_GET['id']))
 59                 {
 60                         $obj = db_find('app_forms_fields_rules',$_GET['id']);
 61                 }
 62                 else
 63                 {
 64                         $obj = db_show_columns('app_forms_fields_rules');
 65                 }
 67                 $fields_id = _get::int('fields_id');
 69                 $field_info = db_find('app_fields', $fields_id);
 71                 $exclude_choices = array();
 72                 $rules_query = db_query("select * from app_forms_fields_rules where fields_id='" . $fields_id . "'" . (isset($_GET['id']) ? " and id!='" . $_GET['id']. "'":''));
 73                 while($rules = db_fetch_array($rules_query))
 74                 {
 75                         if(strlen($rules['choices']))
 76                         {
 77                                 $exclude_choices = array_merge($exclude_choices,explode(',',$rules['choices']));
 78                         }

An attacker either needs administrator privileges or they could trigger this vulnerability through cross-site request forgery.
