CVE-2023-53773Public exploitNetwork attack vector

Unauthenticated live-stream disclosure via snapshot generation

Published Dec 9, 2025 · Updated Apr 7, 2026

Missing authentication in MiniDVBLinux 5.4 and earlier allows remote attackers to retrieve live TV screenshots through its web interface. The web-exposed /var/www/tpl/tv_action.sh invokes SVDRP's GRAB command and moves /tmp/tv.jpg into /var/www/images without checking authentication. No authentication is required; each request generates and exposes a current frame from the active television stream.
