Summary

An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration.

Risk Assessment

An attacker within Wi-Fi range can inject data frames, potentially compromising communication integrity or enabling further attacks.

Recommendation

Update the driver to a version that properly rejects plaintext frames in protected networks, or replace the adapter.
