Code-Projects Online Reviewer System SQL Injection Vulnerability in Exam Update PHP File

A SQL injection vulnerability has been identified in Code-Projects Online Reviewer System version 1.0. The issue arises in the file '/system/system/admins/assessments/pretest/exam-update.php', where the 'test_id' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows attackers to inject malicious SQL, potentially leading to unauthorized database access, data manipulation or deletion, and exposure of sensitive information.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP GET request to 'exam-update.php' with a 'test_id' parameter that includes the SQL injection payload. This can be done using a tool like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure that user input meets expected formats, and database user permissions should be minimized to reduce the impact of potential attacks.
