[原文]Cross-site scripting (XSS) vulnerability in index.php for FlatNuke 2.5.6 allows remote attackers to inject arbitrary web script or HTML via the user parameter in a profile operation, a different vulnerability than CVE-2005-2814. NOTE: it is possible that this XSS is a resultant vulnerability of CVE-2005-3307.
FlatNuke contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'user' or 'nome' variables upon submission to the 'index.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.
