CVE-2025-40634 is a stack-based buffer overflow in the conn-indicator binary on TP-Link Archer AX50 routers running firmware earlier than version 1.0.15 build 241203 rel61480. The affected binary runs as root. An attacker able to reach the router through either its LAN or WAN network interfaces can exploit the overflow to execute arbitrary code on the device.

This repository contains a working exploit for CVE-2025-40634, a stack-based buffer overflow in the TP-Link Archer AX50 router (firmware 1.0.14 Build 20240108 rel.42655(4555)). The exploit targets the 'conn-indicator' binary, which processes DNS responses on random UDP ports between 32000 and 61000. The exploit is implemented in Python (exploit.py) and automates the attack by sending specially crafted DNS response packets to the target router, either from the LAN or by spoofing DNS server IPs for WAN attacks. The payload achieves remote code execution, opening a reverse shell from the router to the attacker's machine. The exploit includes a web server to deliver the reverse shell payload and a netcat listener to receive the shell. The README.md provides a detailed technical analysis of the vulnerability, exploitation process, and usage instructions. The code is operational and requires root privileges to run, as it uses raw sockets and network spoofing. The main entry point is exploit.py, which orchestrates the attack, payload delivery, and shell reception.
