CVE-2020-13594

CVE-2020-13594 concerns the BLE controller in Espressif ESP-IDF 4.2 and earlier for ESP32. The vulnerability arises because the channel map field of the connection request packet is not properly restricted, allowing radio-range attackers to crash the device via a crafted packet ( denial of servic...

Design/Logic Flaw

An encryption-bypass issue was discovered on Espressif ESP-IDF devices through 4.2, ESP8266NONOSSDK devices through 3.0.3, and ESP8266RTOSSDK devices through 3.3. Broadcasting forged beacon frames forces a device to change its authentication mode to OPEN, effectively disabling its 802.11 encrypti...

CVE-2020-12638

The CVE affects Espressif IoT SDKs: ESP-IDF up to 4.2, ESP8266_NONOS_SDK up to 3.0.3, and ESP8266_RTOS_SDK up to 3.3. A forged-beacon-frame exploit forces a device to switch its authentication mode to OPEN, effectively disabling 802.11 encryption. The underlying issue is an encryption bypass trig...
