CVSS 3.1
3.5 lowCVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:NCVE-2020-24588
Low (3.5). EPSS 3.6% chance of exploitation in the next 30 days.
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets.
