CVE-2023-47430Public exploitNetwork attack vector

Remote service crash via unchecked TiVo parameters

Published Mar 25, 2024 · Updated Nov 14, 2024

Stack buffer overflow in ReadyMedia 1.3.3 allows remote attackers to crash the media server through a crafted TiVoConnect request. SendContainer() in tivo_commands.c appends attacker-controlled Filter and SortOrder values to fixed-size stack buffers with strcat() without bounds checks. The TiVo interface must be enabled and reachable; triggering the overflow terminates the daemon and interrupts media service.
