Executive Summary

CVE-2026-2166 is a critical SQL injection vulnerability found in the Online Reviewer System version 1.0, specifically in the /login/index.php file within the Login component.

The vulnerability arises because the application improperly handles the username and password input parameters, incorporating them directly into SQL queries without proper sanitization or validation.

This flaw allows attackers to inject malicious SQL code remotely without any authentication, potentially modifying the intended SQL commands.

Exploitation can bypass authentication controls and manipulate the database, leading to unauthorized access and control over the system.

Detection Guidance

[{'type': 'paragraph', 'content': 'This SQL injection vulnerability can be detected by testing the login interface, specifically the /login/index.php endpoint, for improper handling of the username and password parameters.'}, {'type': 'paragraph', 'content': "One approach is to attempt to inject SQL code into the username or password fields, such as using the input: admin' OR '1'='1, which can bypass authentication if the system is vulnerable."}, {'type': 'paragraph', 'content': 'Automated tools like sqlmap can be used to confirm the presence of the vulnerability by targeting the login endpoint with crafted payloads.'}, {'type': 'list_item', 'content': 'Use sqlmap to test the login page: sqlmap -u "http://target/login/index.php" --data="username=admin&password=admin" --risk=3 --level=5'}, {'type': 'list_item', 'content': "Manually test by sending POST requests with payloads such as username=admin' OR '1'='1 and password=admin' OR '1'='1 to see if authentication is bypassed."}, {'type': 'list_item', 'content': 'Use Google dorking to identify vulnerable targets by searching: inurl:login/index.php'}] [1, 4]

Mitigation Strategies

Immediate mitigation involves preventing the SQL injection by properly handling user inputs in the login functionality.

The recommended fix is to implement prepared statements with parameter binding, which separates SQL code from user input and prevents malicious input from being executed as SQL commands.

If fixing the code is not immediately possible, replacing the affected component with an alternative product is suggested.

Until a fix or replacement is applied, restrict access to the vulnerable login page and monitor for suspicious activity to reduce risk.
