1000 Projects Daily College Class Work Report Book SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in the 'Daily College Class Work Report Book' PHP project, version 1.0. The issue resides in the '/admin_info.php' file, where the 'batch' parameter is processed without proper validation, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows attackers to manipulate SQL queries, potentially leading to unauthorized database access, data modification or deletion, and access to sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/admin_info.php' file with a crafted 'batch' 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, validate and filter user input, minimize database user permissions, and conduct regular security audits.
