| CVE-2023-35818 | 1 Espressif | 44 Esp-eye, Esp-eye Firmware, Esp32-d0wd-v3 and 41 more | 2023-07-28 | N/A | 6.8 MEDIUM |
| An issue was discovered on Espressif ESP32 3.0 (ESP32_rev300 ROM) devices. An EMFI attack on ECO3 provides the attacker with a capability to influence the PC value at the CPU context level, regardless of Secure Boot and Flash Encryption status. By using this capability, the attacker can exploit another behavior in the chip to gain unauthorized access to the ROM download mode. Access to ROM download mode may be further exploited to read the encrypted flash content in cleartext format or execute stub code. | |||||
| CVE-2021-28135 | 1 Espressif | 1 Esp-idf | 2022-07-12 | 3.3 LOW | 6.5 MEDIUM |
| The Bluetooth Classic implementation in Espressif ESP-IDF 4.4 and earlier does not properly handle the reception of continuous unsolicited LMP responses, allowing attackers in radio range to trigger a denial of service (crash) in ESP32 by flooding the target device with LMP Feature Response data. | |||||
| CVE-2021-28136 | 1 Espressif | 2 Esp-idf, Esp32 | 2021-09-09 | 3.3 LOW | 6.5 MEDIUM |
| The Bluetooth Classic implementation in Espressif ESP-IDF 4.4 and earlier does not properly handle the reception of multiple LMP IO Capability Request packets during the pairing process, allowing attackers in radio range to trigger memory corruption (and consequently a crash) in ESP32 via a replayed (duplicated) LMP packet. | |||||
| CVE-2020-12638 | 1 Espressif | 3 Esp-idf, Esp8266 Nonos Sdk, Esp8266 Rtos Sdk | 2021-07-21 | 4.3 MEDIUM | 6.8 MEDIUM |
| An encryption-bypass issue was discovered on Espressif ESP-IDF devices through 4.2, ESP8266_NONOS_SDK devices through 3.0.3, and ESP8266_RTOS_SDK devices through 3.3. Broadcasting forged beacon frames forces a device to change its authentication mode to OPEN, effectively disabling its 802.11 encryption. | |||||
| CVE-2020-13595 | 1 Espressif | 2 Esp-idf, Esp32 | 2020-09-08 | 3.3 LOW | 6.5 MEDIUM |
| The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.0 through 4.2 (for ESP32 devices) returns the wrong number of completed BLE packets and triggers a reachable assertion on the host stack when receiving a packet with an MIC failure. An attacker within radio range can silently trigger the assertion (which disables the target's BLE stack) by sending a crafted sequence of BLE packets. | |||||
| CVE-2020-13594 | 1 Espressif | 2 Esp-idf, Esp32 | 2020-09-08 | 3.3 LOW | 6.5 MEDIUM |
| The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.2 and earlier (for ESP32 devices) does not properly restrict the channel map field of the connection request packet on reception, allowing attackers in radio range to cause a denial of service (crash) via a crafted packet. | |||||
| CVE-2019-17391 | 1 Espressif | 8 Esp32-d0wd, Esp32-d0wd Firmware, Esp32-d2wd and 5 more | 2020-08-24 | 2.1 LOW | 4.6 MEDIUM |
| An issue was discovered in the Espressif ESP32 mask ROM code 2016-06-08 0 through 2. Lack of anti-glitch mitigations in the first stage bootloader of the ESP32 chip allows an attacker (with physical access to the device) to read the contents of read-protected eFuses, such as flash encryption and secure boot keys, by injecting a glitch into the power supply of the chip shortly after reset. | |||||
| CVE-2019-15894 | 1 Espressif | 1 Esp-idf | 2020-08-24 | 7.2 HIGH | 6.8 MEDIUM |
| An issue was discovered in Espressif ESP-IDF 2.x, 3.0.x through 3.0.9, 3.1.x through 3.1.6, 3.2.x through 3.2.3, and 3.3.x through 3.3.1. An attacker who uses fault injection to physically disrupt the ESP32 CPU can bypass the Secure Boot digest verification at startup, and boot unverified code from flash. The fault injection attack does not disable the Flash Encryption feature, so if the ESP32 is configured with the recommended combination of Secure Boot and Flash Encryption, then the impact is minimized. If the ESP32 is configured without Flash Encryption then successful fault injection allows arbitrary code execution. To protect devices with Flash Encryption and Secure Boot enabled against this attack, a firmware change must be made to permanently enable Flash Encryption in the field if it is not already permanently enabled. | |||||
| CVE-2019-12586 | 1 Espressif | 3 Arduino-esp32, Esp-idf, Esp8266 Nonos Sdk | 2020-08-24 | 3.3 LOW | 6.5 MEDIUM |
| The EAP peer implementation in Espressif ESP-IDF 2.0.0 through 4.0.0 and ESP8266_NONOS_SDK 2.2.0 through 3.1.0 processes EAP Success messages before any EAP method completion or failure, which allows attackers in radio range to cause a denial of service (crash) via a crafted message. | |||||
| CVE-2019-12588 | 1 Espressif | 2 Arduino Esp8266, Esp8266 Nonos Sdk | 2019-09-09 | 3.3 LOW | 6.5 MEDIUM |
| The client 802.11 mac implementation in Espressif ESP8266_NONOS_SDK 2.2.0 through 3.1.0 does not validate correctly the RSN AuthKey suite list count in beacon frames, probe responses, and association responses, which allows attackers in radio range to cause a denial of service (crash) via a crafted message. | |||||
| CVE-2018-18558 | 1 Espressif | 1 Esp-idf | 2019-05-14 | 6.9 MEDIUM | 6.4 MEDIUM |
| An issue was discovered in Espressif ESP-IDF 2.x and 3.x before 3.0.6 and 3.1.x before 3.1.1. Insufficient validation of input data in the 2nd stage bootloader allows a physically proximate attacker to bypass secure boot checks and execute arbitrary code, by crafting an application binary that overwrites a bootloader code segment in process_segment in components/bootloader_support/src/esp_image_format.c. The attack is effective when the flash encryption feature is not enabled, or if the attacker finds a different vulnerability that allows them to write this binary to flash memory. | |||||
