Description

The vulnerability allows a remote attacker to take over the installation.

The vulnerability exists due to improper access control in the initial-setup flow when the default admin user has been deleted. A remote attacker can set the password of the default admin user without authentication to take over the installation.

The issue becomes exploitable after the default admin user has been deleted, which causes the initial-setup flow to become available again.


Remediation

Install security update from vendor's website.
