CVE-2024-57678Network attack vector

Unauthenticated wireless MAC ACL modification via POST

Published Jan 16, 2025 · Updated Feb 3, 2025

Incorrect authorization in D-Link DIR-816 A2 firmware 1.10CNB05_R1B011D88210 allows remote attackers to alter both wireless MAC ACLs. The form2WlAc.cgi handler accepts a crafted POST request and writes the supplied 2.4 GHz and 5 GHz access-control settings without enforcing authorization. No authentication or user interaction is required, and the resulting configuration change can admit or block devices on either wireless band.
