itsourcecode Student Management System SQL Injection Vulnerability

A SQL injection vulnerability exists in the itsourcecode Student Management System version 1.0, specifically within the '/addrecord.php' file. The vulnerability arises because the application does not properly sanitize or validate the 'id' parameter before using it in SQL queries. This oversight allows attackers to inject malicious SQL code, potentially leading to unauthorized database access, data manipulation, and other serious security issues. Notably, this vulnerability can be exploited remotely without authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries. This could lead to unauthorized data access, data leakage, data tampering, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request to the '/addrecord.php' file with an injected SQL payload in the 'id' parameter. This can be done 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. 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.
