CVE-2020-24588

Severity CVSS v4.0:
Pending analysis
Type:
CWE-327 Use of a Broken or Risky Cryptographic Algorithm
Publication date:

Description

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.
