[原文]Cross-site scripting (XSS) vulnerability in classifieds/viewcat.cgi in KCScripts Classifieds, distributed individually and as part of Portal Pack 6.0 and earlier, allows remote attackers to inject arbitrary web script or HTML via the cat_id parameter.
KCScripts Portal Pack contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'cat_id' variable upon submission to the 'classifieds/viewcat.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.
