CVE-2021-25485

System-UID file write via Bluetooth path traversal

Published Oct 6, 2021 · Updated Aug 3, 2024

Path traversal in FactoryAirCommandManager on Samsung Mobile Devices before SMR Oct-2021 Release 1 allows attackers to write files via Bluetooth. The Bluetooth remote socket passes an attacker-controlled path to file-writing logic without restricting it to the intended directory. Bluetooth proximity, low privileges, and user interaction are required; resulting files carry the system UID.
