CVE-2024-36782Network attack vector

Root access via hard-coded password

Published Jun 3, 2024 · Updated Feb 13, 2025

Hard-coded credentials in TOTOLINK CP300+ 2.0.4-B20201102 allow remote attackers to log in as root through the management interface. The firmware stores a reusable root password in /etc/shadow.sample instead of requiring a device-specific secret. No prior authentication or user interaction is required, and a successful login grants administrative control of the appliance.
