my little guestbook guestbook.php BBcode link Tag XSS
Remote / Network Access
Loss of Integrity
my little guestbook contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate [link] BBCode tags upon submission to the 'guestbook.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.
