Loading vulnerability…
A vulnerability in the client 802.11 MAC implementation of Espressif ESP8266_NONOS_SDK versions 2.2.0 through 3.1.0 allows attackers within radio range to send crafted beacon frames, probe responses, or association responses with a malformed RSN AuthKey suite list count. The lack of proper validation of this field can cause the device to crash, resulting in a denial of service.

This repository provides proof-of-concept (PoC) exploits for three Wi-Fi vulnerabilities affecting Espressif ESP32 and ESP8266 IoT devices: CVE-2019-12586 (EAP client crash), CVE-2019-12587 (Zero PMK installation/hijack), and CVE-2019-12588 (Beacon frame crash). The structure includes: - Precompiled and source versions of a custom hostapd (hostapd-2.8_binary, hostapd-2.8_source) configured to emulate a malicious access point for triggering the vulnerabilities. - Scripts and firmware for ESP8266/ESP32 clients to test the vulnerabilities (esp_client_test_codes/). - Beacon frame injection tools (beacon_frame_crasher/) in both Arduino (C++) and Python (scapy) for wireless DoS attacks. - All necessary certificates, keys, and configuration files for WPA2-Enterprise EAP testing. The main attack vectors are over Wi-Fi (network/wireless), targeting devices connected to enterprise networks using WPA2-Enterprise. The exploits can cause device hijacking, denial of service (crash/reboot), or forced re-authentication. The repository is well-structured for research and testing, with clear instructions and all required files for reproducing the attacks in a controlled environment.
