WAVLINK Quantum D4G (WN531G3) Pass-The-Hash

Vulnerability Description

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.

Impact Analysis

Refer to official advisory for detailed impact metrics.

Remediation
