Code-Projects Online Job Search Engine SQL Injection Vulnerability in Registration.php

A SQL injection vulnerability has been identified in Code-Projects Online Job Search Engine version 1.0. The issue arises in the registration.php file, where the 'txtusername' parameter is improperly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows attackers to manipulate SQL queries, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/onlineJobSearchEngine/registration.php' file with a crafted 'txtusername' parameter. This parameter should include SQL injection payloads, such as boolean-based or time-based blind injection techniques. The request can be made using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
