Oqtane Framework 6.0.0 is vulnerable to Incorrect Access Control. By manipulating the entityid parameter, attackers can bypass passcode validation and successfully log into the application or access restricted data without proper authorization. The lack of server-side validation exacerbates the issue, as the application relies on client-side information for authentication.
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
