** DISPUTED **  Multiple cross-site scripting (XSS) vulnerabilities in vBulletin 3.6.8 allow remote attackers to inject arbitrary web code or HTML via the (1) s parameter to index.php, and the (2) q parameter to (a) faq.php, (b) member.php, (c) memberlist.php, (d) calendar.php, (e) search.php, (f) forumdisplay.php, (g) showgroups.php, (h) online.php, and (i) sendmessage.php.  NOTE: these issues have been disputed by the vendor, stating "I can't reproduce a single one of these".  The researcher is known to be unreliable.
