1000projects Online Project Report Submission and Evaluation System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in version 1.0 of the 1000projects Online Project Report Submission and Evaluation System. The issue arises in the file '/admin/controller/delete_group_student.php', where the 'batch_id' parameter is improperly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could result in unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a request to the '/admin/controller/delete_group_student.php' file with a crafted 'batch_id' parameter. The injection can be verified by using payloads that exploit SQL injection vulnerabilities, such as those that manipulate boolean conditions or cause SQL errors.

Remediation

It is recommended to implement input validation and sanitization for the 'batch_id' parameter to prevent SQL injection. Additionally, using prepared statements for database queries can help mitigate this vulnerability.
