[原文]Multiple cross-site scripting (XSS) vulnerabilities in Advanced Guestbook 2.2 and 2.3.1 allow remote attackers to inject arbitrary web script or HTML via (1) the entry parameter in index.php and (2) the gb_id parameter in comment.php. NOTE: The index.php/entry vector might be resultant from CVE-2005-1548.
Advanced Guestbook contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate 'gb_id' variable upon submission to the comment.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.
