Directory traversal vulnerability in include/prune_torrents.php in BTI-Tracker 1.3.2 (aka btitracker) allows remote attackers to delete arbitrary files via ".." sequences in the TORRENTSDIR parameter in a prune action.

Multiple SQL injection vulnerabilities in account_change.php in BtiTracker 1.4.1 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) style or (2) langue parameter.

Multiple cross-site scripting (XSS) vulnerabilities in BtiTracker before 1.4.5 allow remote attackers to inject arbitrary web script or HTML via unspecified vectors to (1) account.php, (2) moresmiles.php, or (3) recover.php; or (4) the "to" parameter to usercp.php.

details.php in BtiTracker before 1.4.5, when torrent viewing is disabled for guests, allows remote attackers to bypass protection mechanisms via a direct request, as demonstrated by (1) reading the details of an arbitrary torrent and (2) modifying a torrent owned by a guest.

blocks/shoutbox_block.php in BtiTracker 1.4.4 does not verify user accounts, which allows remote attackers to post shoutbox entries as arbitrary users via a modified nick field.
