CVE-2025-5833

Physical authentication bypass via unprotected root filesystem

Published Jun 25, 2025 · Updated Jun 25, 2025

Insufficient data verification in Pioneer DMH-WT7600NEX 3.05 allows physically proximate attackers to bypass device authentication. The operating-system configuration fails to protect the root filesystem, allowing its contents to be treated as authentic without adequate verification. Physical access to the installed receiver is required; successful exploitation bypasses authentication and compromises system integrity.
