CVE-2024-34211Public exploit

Root access via hardcoded shadow-file password

Published May 9, 2024 · Updated Feb 13, 2025

Hard-coded credentials in TOTOLINK CP450 4.1.0cu.747_B20191224 allow attackers on the adjacent network to log in as root. The firmware ships /etc/shadow.sample with a fixed root password hash whose plaintext is recoverable from the published image. No prior privileges or user interaction are required, and successful authentication grants complete control of the device.
