Campcodes Computer Sales and Inventory System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Campcodes Computer Sales and Inventory System version 1.0. The issue arises in the file '/pages/cust_searchfrm.php?action=edit', where the 'id' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any 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, enabling attackers to manipulate database queries. This could result in unauthorized data access, data leakage, unauthorized data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a GET request to the 'cust_searchfrm.php' page with the 'action' parameter set to 'edit' and the 'id' parameter manipulated to include a crafted SQL payload. The injection can be verified by using payloads that exploit SQL injection vulnerabilities, such as those that cause time delays or error messages revealing database information.

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 mitigate such vulnerabilities.
