Loading vulnerability…
A stack buffer overflow vulnerability exists in the Realtek RTL8710 and other Ameba-based devices within the implementation of the WPA2 4-way handshake. The vulnerability is present in the AES_UnWRAP function, which processes the 'Encrypted GTK' value. An attacker within Wi-Fi range can exploit this by sending a specially crafted Encrypted GTK during the handshake, leading to a stack buffer overflow and potential remote code execution.

This repository is a Proof-of-Concept (PoC) exploit for CVE-2020-27301, a vulnerability in hostapd. The exploit allows an attacker to set up a rogue access point (AP) that leverages a stack buffer overflow in hostapd, potentially leading to code execution or AP reset. The repository contains the full hostapd source tree with modifications, build scripts, documentation, and a Python script (hostapd/poc.py) that generates a crafted payload (payload.bin) to trigger the vulnerability. The exploit is operational on Linux systems with a compatible Wi-Fi interface and is intended for research and demonstration purposes. The main attack vector is network-based, targeting Wi-Fi clients or APs via malicious management frames. The structure is typical for a large C project, with clear separation between documentation, build files, source code, and exploit scripts. No hardcoded IPs or network endpoints are present; the exploit operates at the Wi-Fi protocol level.
