An issue was discovered on NOKIA Airscale ASIKA Single RAN devices before 21B. If/when CSP (as a BTS administrator) removes security hardenings from the Nokia Single RAN BTS baseband unit, the BTS baseband unit diagnostic tool AaShell (which is by default disabled) allows unauthenticated access from the mobile network solution internal BTS management network to the BTS embedded Linux operating-system level.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
