Privilege escalation vulnerability in Lamassu Bitcoin ATM Douro machines, in its 7.1 version, which could allow a local user to acquire root permissions by modifying the updatescript.js, inserting special code inside the script and creating the done.txt file. This would cause the watchdog process to run as root and execute the payload stored in the updatescript.js.
Solution:
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
The product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
