CVE-2025-32063Public exploit

Persistent root SSH via symlinked startup marker

Published Feb 15, 2026 · Updated Feb 15, 2026

Authentication bypass in Bosch Infotainment system ECU 283C30861E allows physically proximate attackers to expose root SSH after reboot. The tty_ssh_level_recheck.sh startup script removes SSHenabled and then touches SSHdisabled without rejecting a symbolic link between those marker names, recreating SSHenabled. The attacker must first gain local ECU access, create the link, and add a controlled Wi-Fi network; startup then enables SSH and disables the firewall.
