CodeAstro Payroll System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in CodeAstro Payroll System version 1.0. The issue arises in the '/PayrollSy-PHP/home_salary.php' file, where the 'salary_rate' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, leading to unauthorized database access, data manipulation, and potential disruption of services.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, leakage of sensitive information, and could disrupt services, posing a significant risk to system security and business operations.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/PayrollSy-PHP/update_salary.php' endpoint with a crafted 'salary_rate' parameter that includes malicious SQL code. This injected SQL is executed by the database, allowing the attacker to manipulate database queries and access or modify data unlawfully.

Remediation

To address this vulnerability, 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.
