Unauthenticated Command Injection in TP-Link Archer AX21 /locale Endpoint

This repository is a Go-based proof-of-concept exploit for CVE-2023-1389, targeting TP-Link Archer AX21 routers vulnerable to unauthenticated command injection. The main file, main.go, reads a list of target IP addresses from 'list.txt' and attempts to exploit each by sending a crafted HTTPS request to the /cgi-bin/luci/ endpoint, injecting a reverse shell payload. The payload causes the target device to connect back to the attacker's netcat listener, granting a remote shell. The exploit supports concurrent execution using goroutines and a concurrency manager. The repository includes a README with usage instructions, a Go module definition, and dependencies for command-line flag parsing and concurrency control. No detection or scanning functionality is present; the tool is strictly for exploitation. The main attack vector is network-based, exploiting a web interface on the target devices.

This repository contains two Python proof-of-concept exploits for CVE-2023-1389, an unauthenticated command injection vulnerability in the TP-Link Archer AX21 (AX1800) router's web management interface. The vulnerability exists in the 'country' parameter of the 'write' callback at the '/cgi-bin/luci/;stok=/locale' endpoint, allowing arbitrary command execution as root without authentication. - 'archer-file-transfer.py' allows the attacker to execute arbitrary commands on the router and exfiltrate their output by writing to '/tmp/out' and transferring it via netcat to the attacker's machine. - 'archer-rev-shell.py' provides a simpler method to obtain a reverse shell on the attacker's system using netcat. Both scripts require the attacker to specify the router's IP, their own IP, and a listening port. The exploit works by sending crafted GET requests to the vulnerable endpoint, leveraging command injection in the 'country' parameter. The README provides usage instructions and mitigation advice. The repository is structured with a README and two Python scripts, both of which are functional proof-of-concept exploits for the described vulnerability.
