| CVE-2021-41104 | 2 Esphome, Espressif | 3 Esphome Firmware, Esp32, Esp8266 | 2021-10-07 | 4.3 MEDIUM | 7.5 HIGH |
| ESPHome is a system to control the ESP8266/ESP32. Anyone with web_server enabled and HTTP basic auth configured on version 2021.9.1 or older is vulnerable to an issue in which `web_server` allows over-the-air (OTA) updates without checking user defined basic auth username & password. This issue is patched in version 2021.9.2. As a workaround, one may disable or remove `web_server`. | |||||
