Summary

Control Web Panel before webpanel_version 1.29 does not require authentication for root-privileged routes on its loopback API service. A local user with low privileges can reach that API without an access token and perform unauthorized actions with root rights (CWE-306).

Description from the CNA

Control Web Panel (CWP) before webpanel_version 1.29 contains a missing authentication vulnerability that allows attackers able to reach the loopback API service to invoke root-privileged API routes without presenting an access token. Attackers can access endpoints such as /v1/restoredatabase/, /generaluser/, /last_access/, /valid_user/, /valid_token/, and /user_panel_dashboard/ to perform unauthorized actions with root privileges.
