Emefa Guestbook sign.asp Multiple Field Arbitrary HTML Injection
Remote / Network Access
Emefa Guestbook contains a flaw that allows arbitrary HTML injection. This flaw exists because the application does not validate name, email, location and message variables upon submission to the 'sign.asp' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
