PHPGurukul Online Birth Certificate System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Online Birth Certificate System version 2.0. The issue arises in the file '/admin/all-applications.php', where the 'del' parameter is improperly processed, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially leading to unauthorized database access, data manipulation, and execution of malicious operations on the server.

Impact

Exploitation of this vulnerability allows for unauthorized database access, data leakage, manipulation of database records, and in some cases, execution of arbitrary code on the server.

Reproduction

The vulnerability can be reproduced by sending a GET request to '/obcs/admin/all-applications.php' with a crafted 'del' parameter that includes malicious SQL code. The injected SQL is executed by the application, allowing the attacker to manipulate the database. For example, using SQL injection techniques such as stacked queries can exploit this vulnerability.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure that user input meets expected formats, blocking malicious data. Finally, database user permissions should be minimized, granting only necessary access rights to the application.
