Technical details
An access control vulnerability in Samsung mTower fails to properly validate client identity before allowing a Normal World application to open TA sessions or close existing sessions if their identifiers are known. The vulnerability is a missing or insufficient authorization check on session operations, allowing arbitrary applications to invoke TA commands. A fix enforces per-TA access control lists (ACLs) and client identity verification on session open.
