CVE-2023-4169Network attack vector

Administrator password reset via insufficient endpoint authorization

Published Aug 5, 2023 · Updated Aug 2, 2024

Improper access control in Ruijie RG-EW1200G 1.0(1)B1P5 allows remote authenticated users to change the administrator password. The /api/sys/set_passwd handler processes an administrator-password change without enforcing administrator-level authorization. Low-privileged access is required; changing the credential enables administrative control and can interrupt legitimate management access.
