CVE-2023-24147Network attack vector

Telnet access via hard-coded password

Published Feb 3, 2023 · Updated Mar 26, 2025

Use of hard-coded credentials in TOTOLINK CA300-PoE 6.2c.884 allows remote attackers to access its Telnet service. The firmware stores a fixed Telnet password in /etc/config/product.ini, causing every affected device to rely on a recoverable shared credential. Network reachability to Telnet and knowledge of the embedded password are sufficient for unauthorized service access and disclosure of data available through that session.
