"An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The
WEP, WPA, WPA2, and WPA3 implementations accept plaintext A-MSDU
frames as long as the first 8 bytes correspond to a valid RFC1042
(i.e., LLC/SNAP) header for EAPOL. An adversary can abuse this to
inject arbitrary network packets independent of the network
configuration.

This plugin only works with Tenable.ot.
