A miscommunication in the file system allows adversaries with access to the MU320E to escalate privileges on the MU320E (all firmware versions prior to v04A00.1).
The product performs an operation at a privilege level that is higher than the minimum level required, which creates new weaknesses or amplifies the consequences of other weaknesses.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
