CVSS v3.1
Official Description
The WPS implementation on I-O DATA DEVICE WN-GDN/R3, WN-GDN/R3-C, WN-GDN/R3-S, and WN-GDN/R3-U devices does not limit PIN guesses, which allows remote attackers to obtain network access via a brute-force attack.
Technical Analysis
CVE-2016-1206 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
