CVE-2023-24502

Unauthorized Wi-Fi access via SSID-derived password

Published Apr 17, 2023 · Updated Feb 6, 2025

Weak password generation in Electra Central AC controllers v4, v5, v7, and v8 allows physically proximate attackers to join the setup hotspot. Before cloud configuration, the controller derives the hotspot password by replacing SSID with PASS in the broadcast network name. Wi-Fi range is sufficient to calculate the credential and access the unit network, exposing other reachable controller functions.
