Authentication Bypass by Capture-replay

CVE-2022-40621

High
7.5/10

Summary

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.

CWE-294 - Authentication Bypass by Capture-replay

A capture-replay flaw exists when the design of the software makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
