## Forward Shell
You might find cases where you have a **RCE in a web app in a, Linux machine** but due to Iptables rules or other kind of filtering **you cannot get a reverse shell**. This "shell" allows you to maintain a PTY shell through that RCE using pipes inside the victim system.\
You can find the code in [**https://github.com/IppSec/forward-shell**](https://github.com/IppSec/forward-shell)****
You just need to modify:
* The URL of the vulnerable host
* The prefix and suffix of your payload (if any)
* The way the payload is sent (headers? data? extra info?)
Then, you can just **send commands** or even **use the `upgrade` command** to get a full PTY (note that pipes are read and written with an approximate 1.3s delay).
