Multiple cross-site scripting (XSS) vulnerabilities in the web based operator client in LiveZilla before 5.1.2.1 allow remote attackers to inject arbitrary web script or HTML via the (1) name of an uploaded file or (2) customer name in a resource created from an uploaded file, a different vulnerability than CVE-2013-7003.

LiveZilla before 5.1.2.1 includes the operator password in plaintext in Javascript code that is generated by lz/mobile/chat.php, which might allow remote attackers to obtain sensitive information and gain privileges by accessing the loginName and loginPassword variables using an independent cross-site scripting (XSS) attack.

The setCookieValue function in _lib/functions.global.inc.php in LiveZilla before 5.1.2.1 allows remote attackers to execute arbitrary PHP code via a serialized PHP object in a cookie.

LiveZilla 5.1.2.1 and earlier includes the MD5 hash of the operator password in plaintext in Javascript code that is generated by lz/mobile/chat.php, which allows remote attackers to obtain sensitive information and gain privileges by accessing the loginName and loginPassword variables using an independent cross-site scripting (XSS) attack. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-7033.

Cross-site scripting (XSS) vulnerability in knowledgebase.php in LiveZilla before 7.0.8.9 allows remote attackers to inject arbitrary web script or HTML via the search-for parameter.

LiveZilla Server before 8.0.1.1 is vulnerable to XSS in the chat.php Create Ticket Action.

LiveZilla Server before 8.0.1.1 is vulnerable to XSS in the ticket.php Subject.

An issue was discovered in chat.php in LiveZilla Live Chat 8.0.1.3 (Helpdesk). A blind JavaScript injection lies in the name parameter. Triggering this can fetch the username and passwords of the helpdesk employees in the URI. This leads to a privilege escalation, from unauthenticated to user-level access, leading to full account takeover. The attack fetches multiple credentials because they are stored in the database (stored XSS). This affects the mobile/chat URI via the lgn and psswrd parameters.
