Code-Projects Library System SQL Injection Vulnerability in Student Issue Book Processing

A critical SQL injection vulnerability has been identified in Code-Projects Library System version 1.0. The issue arises in the file '/student-issue-book.php', where the 'reg' parameter is manipulated, leading to unauthorized database access. This vulnerability can be exploited remotely, without any authentication, allowing attackers to inject malicious SQL queries that could be used to access, modify, or delete database information.

Impact

Exploitation of this vulnerability allows for unauthorized database access via SQL injection, enabling attackers to read, modify, or delete data. This could also lead to unauthorized access to sensitive information and potentially allow attackers to execute administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/student-issue-book.php' with a crafted 'reg' parameter that includes malicious SQL payloads. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, 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.
