[原文]Multiple cross-site scripting (XSS) vulnerabilities in addguest.cgi in Big Webmaster Guestbook Script 1.02 and earlier allow remote attackers to inject arbitrary web script or HTML via the (1) mail, (2) site, (3) city, (4) state, (5) country, and possibly (6) name fields, which are viewed via viewguest.cgi.
Big Webmaster Guestbook addguest.cgi Multiple Field XSS
Remote / Network Access
Loss of Integrity
Big Webmaster Guestbook contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'name', 'mail', 'site', 'city', 'state' and 'country' fields upon submission to the 'addguest.cgi' 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.
