Doctormms v1.0 was discovered to contain a SQL injection vulnerability via the $userid parameter at myAppoinment.php. NOTE: this is disputed by a third party who claims that the userid is a session variable controlled by the server, and thus cannot be used for exploitation. The original reporter counterclaims that this originates from $_SESSION["userid"]=$_POST["userid"] at line 68 in doctors\doctorlogin.php, where userid under POST is not a session variable controlled by the server.
