PHPGurukul Beauty Parlour Management System SQL Injection Vulnerability in All Appointment Management File

A SQL injection vulnerability has been identified in PHPGurukul Beauty Parlour Management System version 1.1. The issue arises in the file '/admin/all-appointment.php', where the 'delid' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized access to the database, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries. This could lead to unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a GET request to '/bpms/admin/all-appointment.php' with the 'delid' parameter. Include a payload that exploits time-based blind SQL injection, such as one that uses 'RLIKE' to test for SQL injection vulnerabilities by causing a delay in the response.

Remediation

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 the necessary rights for operations, and avoiding high-privilege accounts.
