Code-Projects Accounting System SQL Injection Vulnerability in Parameter Handler Component

A SQL injection vulnerability has been identified in Code-Projects Accounting System version 1.0. The issue resides in the Parameter Handler component, specifically within the '/edit_costumer.php' file. The vulnerability is triggered by manipulating the 'cos_id' parameter, which allows attackers to inject malicious SQL queries. This injection can be executed remotely, without the need for authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries to gain unauthorized access to the database, retrieve, modify or delete data, and access sensitive information. Such actions can disrupt services and pose a significant threat to overall system security and business operations.

Reproduction

The vulnerability can be reproduced by sending a crafted request to the '/edit_costumer.php' file with a 'cos_id' parameter that includes malicious SQL code. This can be done using a web browser, a tool like curl, or an automated vulnerability scanner that supports SQL injection testing, such as sqlmap.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance overall security.
