Cross-site scripting (XSS) vulnerability in Nuked Klan 1.7 and earlier allows remote attackers to inject arbitrary web script or HTML via a javascript: URI in a getURL statement in a .swf file, as demonstrated by "Remote Cookie Disclosure."

Multiple directory traversal vulnerabilities in Nuked-KlaN 1.4b and 1.5b allow remote attackers to read or include arbitrary files via .. sequences in (1) the userlangue parameter to index.php or (2) the langue parameter to update.php, or modify arbitrary GLOBAL variables by causing globals.php to be loaded before conf.inc.php via (3) .. sequences in the file parameter with the page parameter set to globals, or (4) ../globals.php in the userlangue parameter, as demonstrated by modifying $nuked[prefix] in the Suggest module.
