CVE-2022-47209

Support-account access via hard-coded credentials

Published Dec 16, 2022 · Updated Apr 17, 2025

Hard-coded credentials in NETGEAR RAX30 firmware before 1.0.9.90 allow remote attackers on the adjacent network to access a support account. The /etc/passwd file defines support as a UID-0 account with the fixed password support, and normal administration cannot change that password. Exploitation requires access to the router's network segment; the account cannot use the web UI or standard interfaces, and the reachable service is undisclosed.
