CVE-2024-23930

Denial of service via Media service error handling

Published Jan 31, 2025 · Updated Aug 26, 2025

Denial of service in all Pioneer DMH-WT7600NEX firmware versions allows network-adjacent attackers to interrupt service via TCP port 42000. The default Media service improperly handles error conditions in requests received on that port; no lower-level fault has been published. No authentication or user interaction is required from an adjacent network, and successful exploitation interrupts device availability.
