PHPGurukul Bank Locker Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Bank Locker Management System version 1.0. The issue resides in the file '/banker/changeidproof.php', specifically within the 'editid' parameter. This vulnerability allows remote attackers to inject malicious SQL queries, leading to unauthorized database access, data manipulation, and potential leakage of sensitive information. The vulnerability arises from inadequate input validation, allowing attackers to exploit the 'editid' parameter without authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries to gain unauthorized access to the database, modify or delete data, and access sensitive information. This poses a significant risk to the overall security of the application and its data integrity.

Reproduction

The vulnerability can be reproduced by sending a request to the 'changeidproof.php' file with a crafted 'editid' parameter that includes malicious SQL payloads. This can be done using tools like sqlmap, which automate the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to implement input validation and use prepared statements to prevent SQL injection. Regular security audits should also be conducted to identify and address potential vulnerabilities.
