[原文]Multiple cross-site scripting (XSS) vulnerabilities in Infopop UBB.Threads before 6.5.2 Beta allow remote attackers to inject arbitrary web script or HTML via the (1) Searchpage parameter to dosearch.php, (2) Number, (3) what, or (4) page parameter to newreply.php, (5) Number, (6) Board, or (7) what parameter to showprofile.php, (8) fpart or (9) page parameter to showflat.php, or (10) like parameter to showmembers.php.
UBB.threads contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'Number', 'what', & 'page' variables upon submission to the 'newreply.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.
Upgrade to version 6.5.2 beta or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
