[原文]Cross-site scripting (XSS) vulnerability in sign.php in codegrrl SimpBook 1.0, when html_enable is on, allows remote attackers to inject arbitrary web script or HTML via the message parameter to index.php.
Codegrrl SimpBook contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate input supplied to the guestbook message body. 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.
