| CVE-2023-46894 | 1 Espressif | 1 Esptool | 2023-11-15 | N/A | 7.5 HIGH |
| An issue discovered in esptool 4.6.2 allows attackers to view sensitive information via weak cryptographic algorithm. | |||||
| CVE-2022-24893 | 1 Espressif | 1 Esp-idf | 2022-07-08 | 8.3 HIGH | 8.8 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-2021-41104 | 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`. | |||||
| CVE-2021-28139 | 1 Espressif | 2 Esp-idf, Esp32 | 2021-09-09 | 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-2021-34173 | 1 Espressif | 2 Esp32, Esp32 Firmware | 2021-07-27 | 7.8 HIGH | 7.5 HIGH |
| An attacker can cause a Denial of Service and kernel panic in v4.2 and earlier versions of Espressif esp32 via a malformed beacon csa frame. The device requires a reboot to recover. | |||||
| CVE-2020-16146 | 1 Espressif | 1 Esp-idf | 2021-01-20 | 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-2019-12587 | 1 Espressif | 2 Esp-idf, Esp8266 Nonos Sdk | 2020-08-24 | 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. | |||||
