HIGH 8.8MITIGATE

CVE-2024-23726 is a high-severity flaw (CVSS 8.8) affecting ddw365 firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Ubee DDW365 XCNDDW365 devices have predictable default WPA2 PSKs that could lead to unauthorized remote access. A remote attacker (in proximity to a Wi-Fi network) can derive the default WPA2-PSK value by observing a beacon frame. A PSK is generated by using the first six characters of the SSID and the last six of the BSSID, decrementing the last digit.
