Kidaze Course Selection System SQL Injection Vulnerability in COUNT3s6.php

A SQL injection vulnerability has been identified in the Kidaze Course Selection System, specifically in version 1.0 prior to commit 42cd892b40a18d50bd4ed1905fa89f939173a464. The issue arises in the file '/Profilers/PriProfile/COUNT3s6.php', where the 'cpu' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access and potential data manipulation.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, and access to sensitive information. Such actions pose a significant threat to system security and data integrity.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/Profilers/PriProfile/COUNT3s6.php' with the 'cpu' parameter. The injection can be crafted using boolean-based or time-based payloads, taking advantage of the application's SQL query handling.

Remediation

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.
