Executive Summary

This vulnerability exists in ZKTeco ZKBioSecurity 3.0 and is a cross-site request forgery (CSRF) issue. It allows attackers to perform administrative actions by tricking users who are already logged in into visiting malicious websites.

As a result, unauthorized administrative access can be gained by the attacker through these newly created superadmin accounts.

Impact Analysis
