MajorDoMo (aka Major Domestic Module) contains a reflected cross-site scripting (XSS) vulnerability in command.php. The $qry parameter is rendered directly into the HTML page without sanitization via htmlspecialchars(), both in an input field value attribute and in a paragraph element. An attacker can inject arbitrary JavaScript by crafting a URL with malicious content in the qry parameter.
