CVE-2023-53774Public exploitNetwork attack vector

Unauthenticated VDR control via exposed SVDRP command handler

Published Dec 9, 2025 · Updated Apr 7, 2026

Missing authentication in MiniDVBLinux 5.4 allows remote attackers to control VDR functions through crafted SVDRP commands. The port 8008 web command handler passes its command parameter to svdrpsend.sh without requiring authentication. Network access to that interface is sufficient; demonstrated impact includes queueing TV-screen messages, while other SVDRP commands manipulate recorder operations.
