Insecure Communication and Hashing Vulnerability in WAVLINK Quantum D4G (WN531G3) Firmware

CVE-2022-40621 · HIGH Severity

CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H

Because the WAVLINK Quantum D4G (WN531G3) running firmware version M31G3.V5030.200325 and earlier communicates over HTTP and not HTTPS, and because the hashing mechanism does not rely on a server-supplied key, it is possible for an attacker with sufficient network access to capture the hashed password of a logged on user and use it in a classic Pass-the-Hash style attack.
