Wordpress Export Users to CSV 1.1.1 Plugin - CSV Injection Vulnerability
[# Exploit Title: Wordpress Plugin Export Users to CSV 1.1.1 - CSV Injection # Exploit Author: Javier Olmedo # Website: https://hackpuntes.com # Vendor: Matt Cromwell # Software Link: https://wordpress.org/plugins/export-users-to-csv/ # Affected Version: 1.1.1 and before # Active installations: +20,000 # Patched Version: unpatched # Category: Web Application # Platform: PHP # Tested on: Win10x64 # 1. Plugin Description: # WordPress Export Users to CSV plugin exports user data and meta data. # You can even export the users by role and registration date range. # 2. Technical Description: # WordPress Export users to CSV plugin version 1.1.1. 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 his profile and these commands are executed when a user with greater privilege # exports the data in CSV and opens that file on his machine. # 3. Proof Of Concept (PoC): # Enter the payload =SUM(1+1)*cmd|' /C calc'!A0 in any field of the profile, for example, in biography. # 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. # 4. 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 # 0day.today [2024-11-16] #
