#================================================# Severity: Moderately Critical #
# # #
# Oh wow no-content space! Enjoy it! # Proud To Be Italian. #
# # #
#====================================#===========#================================================#
# Proof Of Concept / Bug Explanation # #
#====================================# #
# PHP-Fusion presents a critical vulnerability in submit.php page. Let's see source: #
#=================================================================================================#
[Submit.php]
1. if ($stype == "l") {
2.
3. if (isset($_POST['submit_link'])) {
4.
5. if ($_POST['link_name'] != "" && $_POST['link_url'] != "" && $_POST['link_description'] != "") {
6. $submit_info['link_category'] = stripinput($_POST['link_category']);
7. $submit_info['link_name'] = stripinput($_POST['link_name']);
8. $submit_info['link_url'] = stripinput($_POST['link_url']);
9. $submit_info['link_description'] = stripinput($_POST['link_description']);
10. $result = dbquery("INSERT INTO ".$db_prefix."submissions (submit_type, submit_user, submit_datestamp, submit_criteria) VALUES ('l', '".$userdata['user_id']."', '".time()."', '".serialize($submit_info)."')");
#=================================================================================================#
# Look to the sql query. #
# There are two variables: $userdata['user_id'] and a serialized array $submit_info. #
# The user_id is an intval value and array values link_category, link_name, link_url and #
# link_description are correctly cleaned via fusions' stripinput() function. #
# #
# All seems pretty cleaned. #
# But what would happen if we set another value into submit_info[] array via gpc vars? #
# It will be set in the serialized array, and obvious it will not checked by stripinput. #
# Sql Injection possibility! #
# #
# Let's see: #
# #
# Host: 127.0.0.1 #
# POST PHP-Fusion/submit.php?stype=l #
# link_category=1 link_name=1 link_url=1 link_description=1 submit_info[paradox]=' submit_link=1 #
# #
# It will result in sql error in case of Mq = 0 : #
# #
# You have an error in your SQL syntax; check [...] #
# #
#=================================================================================================#
# Normally to make this trick working register_globals = 1 is needed, but in php-fusion uses #
# extract() to simulate register_globals when it is set to 0. #
#=================================================================================================#
# Use this at your own risk. You are responsible for your own deeds. #
#=================================================================================================#
