[原文]Multiple cross-site scripting (XSS) vulnerabilities in osTicket allow remote attackers to inject arbitrary web script or HTML via (1) the t parameter to view.php, (2) the osticket_title parameter to header.php, (3) the em parameter to admin_login.php, (4) the e parameter to user_login.php, (5) the err parameter to open_submit.php, or (6) the name and subject fields when adding a ticket.
osTicket contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'e' variable upon submission to the user_login.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 1.3.1 or higher, as it has been reported to fix this vulnerability. In addition, osTicket.com has released a patch for some older versions.
