NVD Description

Note: Versions mentioned in the description apply only to the upstream dhcpcd package and not the dhcpcd package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

Bootimus through 0.1.70 contains a broken access control vulnerability that allows authenticated low-privileged users to perform administrative actions by exploiting missing role enforcement in the JWTMiddleware function in internal/auth/auth.go, which validates JWT tokens and account status but fails to inspect the is_admin flag. Attackers can send requests to any endpoint under the /api/users path to create new administrator accounts or reset administrator passwords, thereby gaining full control of the server and the ability to modify boot menus and installation scripts served to PXE clients.
