Cross-site scripting (XSS) vulnerability in admin.php in TorrentFlux 2.1 allows remote attackers to inject arbitrary web script or HTML via (1) the $useragent variable, probably obtained from the User-Agent HTTP header, and possibly (2) the $ipresolved variable.

Directory traversal vulnerability in dir.php in TorrentFlux 2.1 allows remote attackers to list arbitrary directories via "\.\./" sequences in the dir parameter.

Multiple cross-site scripting (XSS) vulnerabilities in TorrentFlux 2.1 allow remote attackers to inject arbitrary web script or HTML via the (1) action, (2) file, and (3) users array variables in (a) admin.php, which are not properly handled when the administrator views the Activity Log; and the (4) torrent parameter, as used by the displayName variable, in (b) startpop.php, different vectors than CVE-2006-5227.
