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.

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.

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.

Multiple cross-site scripting (XSS) vulnerabilities in LiveZilla before 5.1.2.0 allow remote attackers to inject arbitrary web script or HTML via the (1) full name field, (2) company field, or (3) filename to chat.php.

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.
