CVE-2023-1389 is an unauthenticated command injection vulnerability affecting TP-Link Archer AX21 (AX1800) routers running firmware before 1.1.4 Build 20230219. The flaw resides in the web management interface’s locale API at the /cgi-bin/luci;stok=/locale endpoint. During a write operation on the country form, attacker-controlled input supplied through the country parameter is not properly sanitized before being incorporated into a shell command and executed via popen() in the country configuration handling path, described in public analyses as merge_country_config or merge_config_by_country. Because the vulnerable code executes the resulting command in the context of the router management process, a remote attacker can send a crafted POST request and achieve arbitrary command execution as root without authentication. Public reporting also notes that the issue was demonstrated in LAN-reachable scenarios, and separate research described a race-condition-based path that could expose the vulnerable functionality from the WAN side on some configurations.

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.
