CVE-2022-44356Public exploitNetwork attack vector

Unauthenticated device-data disclosure via unrestricted downloads

Published Nov 29, 2022 · Updated Apr 25, 2025

Access control failure in WAVLINK Quantum D4G firmware M31G3.V5030.201204 and M31G3.V5030.200325 allows remote attackers to read device files. The public disclosure omits the request path and handler but reports that download access lacks authentication and that configuration data includes administrator credentials. Network reachability to the interface is sufficient; the reported consequence is disclosure of stored configuration data, logs, and credentials, not modification or service interruption.
