LiveZilla blind Javascript Injection – Cross Site Scripting (XSS)

Overview :
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.
Affected Product(s) :
  • LiveZilla Live Chat 8.0.1.3
Vulnerability Details :
CVE ID :

CVE-2020-9758

The leakage of credentials through the URI may be the result of the autologin feature. Also more parameters in the chat.php form may be vulnerable.
