CodeAstro Online Classroom SQL Injection Vulnerability in addnewfaculty File

A SQL injection vulnerability has been identified in CodeAstro Online Classroom version 1.0. The issue arises in the addnewfaculty file, where the fname parameter is not properly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could result in unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to the /OnlineClassroom/addnewfaculty endpoint. Include the fname parameter with a crafted payload that exploits the SQL injection flaw, such as one that uses SQL injection techniques like error-based or time-based blind injection. The request should be made with a valid PHP session cookie.

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.
