| CVE-2022-24893 | 1 Espressif | 1 Esp-idf | 2024-11-21 | 8.3 HIGH | 7.5 HIGH |
| ESP-IDF is the official development framework for Espressif SoCs. In Espressif’s Bluetooth Mesh SDK (`ESP-BLE-MESH`), a memory corruption vulnerability can be triggered during provisioning, because there is no check for the `SegN` field of the Transaction Start PDU. This can result in memory corruption related attacks and potentially attacker gaining control of the entire system. Patch commits are available on the 4.1, 4.2, 4.3 and 4.4 branches and users are recommended to upgrade. The upgrade is applicable for all applications and users of `ESP-BLE-MESH` component from `ESP-IDF`. As it is implemented in the Bluetooth Mesh stack, there is no workaround for the user to fix the application layer without upgrading the underlying firmware. | |||||
| CVE-2021-28139 | 1 Espressif | 2 Esp-idf, Esp32 | 2024-11-21 | 8.3 HIGH | 8.8 HIGH |
| The Bluetooth Classic implementation in Espressif ESP-IDF 4.4 and earlier does not properly restrict the Feature Page upon reception of an LMP Feature Response Extended packet, allowing attackers in radio range to trigger arbitrary code execution in ESP32 via a crafted Extended Features bitfield payload. | |||||
| CVE-2021-28136 | 1 Espressif | 2 Esp-idf, Esp32 | 2024-11-21 | 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-2021-28135 | 1 Espressif | 1 Esp-idf | 2024-11-21 | 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-2020-16146 | 1 Espressif | 1 Esp-idf | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| Espressif ESP-IDF 2.x, 3.0.x through 3.0.9, 3.1.x through 3.1.7, 3.2.x through 3.2.3, 3.3.x through 3.3.2, and 4.0.x through 4.0.1 has a Buffer Overflow in BluFi provisioning in btc_blufi_recv_handler function in blufi_prf.c. An attacker can send a crafted BluFi protocol Write Attribute command to characteristic 0xFF01. With manipulated packet fields, there is a buffer overflow. | |||||
| CVE-2020-13595 | 1 Espressif | 2 Esp-idf, Esp32 | 2024-11-21 | 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 | 2024-11-21 | 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-2020-12638 | 1 Espressif | 3 Esp-idf, Esp8266 Nonos Sdk, Esp8266 Rtos Sdk | 2024-11-21 | 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-2019-15894 | 1 Espressif | 1 Esp-idf | 2024-11-21 | 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-2019-12587 | 1 Espressif | 2 Esp-idf, Esp8266 Nonos Sdk | 2024-11-21 | 4.8 MEDIUM | 8.1 HIGH |
| 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 allows the installation of a zero Pairwise Master Key (PMK) after the completion of any EAP authentication method, which allows attackers in radio range to replay, decrypt, or spoof frames via a rogue access point. | |||||
| CVE-2019-12586 | 1 Espressif | 3 Arduino-esp32, Esp-idf, Esp8266 Nonos Sdk | 2024-11-21 | 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-2018-18558 | 1 Espressif | 1 Esp-idf | 2024-11-21 | 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. | |||||
