SourceCodester Class and Exam Timetabling System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the SourceCodester Class and Exam Timetabling System, specifically in version 1.0. The issue arises in the file '/edit_room1.php', where the 'id' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Reproduction

The vulnerability can be reproduced by sending a crafted request to the '/edit_room1.php' file with a manipulated 'id' parameter. Various payloads can be used to exploit the SQL injection, such as boolean-based blind, error-based, time-based blind, and UNION query injection techniques. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, 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.
