On affected Arista Wi-Fi access points with captive portal, or application firewall enabled on at least one SSID, a vulnerability in the wireless gateway service could allow an unauthenticated network-adjacent attacker to send a crafted packet that triggers a stack overflow, resulting in a denial-of-service condition or potentially execute arbitrary code on the device. The wireless gateway service is automatically restarted after a crash, allowing repeated exploitation attempts.
