CVE-2022-36526Network attack vector

Unauthenticated management access via phpcgi_main bypass

Published Aug 15, 2022 · Updated Jul 9, 2026

Authentication bypass in D-Link GO-RT-AC750 revision A 101b03 and revision B 200b02 allows remote attackers to alter settings without credentials. The phpcgi_main function in cgibin fails to enforce authentication before processing management requests; the public record does not disclose the exact faulty check or request form. The web-based management interface must be network-reachable, and no confidentiality or availability consequence is reported.
