CVE-2024-23726

Unauthorized Wi-Fi access via predictable default PSK

Published Jan 21, 2024 · Updated May 30, 2025

Predictable default WPA2 credentials in Ubee DDW365 XCNDDW365 devices allow remote attackers to gain unauthorized Wi-Fi access. The key generator concatenates the first six SSID characters with the final six BSSID characters, then decrements the last digit. Exploitation requires wireless proximity and observation of a beacon frame, after which the derived default PSK grants network access.
