PHP-Gastebuch guestbook_newentry.php Kommentar Field XSS
Remote / Network Access
Loss of Integrity
PHP-Gastebuch contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the Kommentar field upon submission to the guestbook_newentry.php 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.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
