Administrative access via hardcoded default root credentials
Published Aug 27, 2024 · Updated Aug 28, 2024
Weak default credentials in Teldat RS123 and RS123w router firmware allow remote attackers to gain full administrative access. The firmware ships with a root account whose password is also root, and enabled Telnet, SSH, HTTP, HTTPS, or FTP services accept those credentials. Exploitation requires network reachability to a management service and unchanged factory credentials, after which the attacker controls the router.
