Summary

Arista Wi-Fi Access Points from 22.0.0 through 22.0.1F-32, from 21.3.0 through 21.3.0M-13, and from 1.0.0 before 21.3.0 are affected when Wireless Intrusion Prevention System (WIPS) is active. An out-of-bounds write (CWE-787) lets an unauthenticated attacker within radio frequency proximity send a crafted frame that crashes the sensor service, and potentially achieves remote code execution. No wireless association or authentication is required.

Description from the CNA

On affected Arista access points with Wireless Intrusion Prevention System (WIPS) active, an unauthenticated attacker within radio frequency (RF) proximity can send a crafted frame to crash the sensor service, disabling WIPS monitoring on the access point, or potentially achieve remote code execution. No wireless association or authentication is required.
