CVE-2023-40931 Scanner

Nagios XI is a powerful IT infrastructure monitoring tool widely used by enterprises to monitor applications, networks, and servers. It offers a web-based interface and advanced monitoring capabilities, making it a preferred choice for IT administrators. The software supports custom dashboards, provides visualization for performance data, and can integrate with multiple third-party applications. Users can leverage Nagios XI to set up alerts for various incidents and manage systems proactively. However, vulnerabilities in its configuration can expose systems to potential risks.

This SQL injection vulnerability exists in Nagios XI versions 5.11.0 to 5.11.1. An attacker with authenticated access can exploit the vulnerability by sending crafted SQL commands through the ID parameter in POST requests. Successful exploitation may allow attackers to execute arbitrary SQL commands, which could compromise database security. Such vulnerabilities are critical because they can expose sensitive data to unauthorized access.

The SQL injection vulnerability in Nagios XI stems from inadequate input validation on the ID parameter in the POST request to /nagiosxi/admin/banner_message-ajaxhelper.php. By manipulating the ID parameter, authenticated attackers can insert malicious SQL commands. This unchecked SQL command injection can interact with the database directly, circumventing proper authentication mechanisms. Attackers can exploit this vulnerability to read or modify data within the database. The lack of input sanitization and proper validation on this endpoint makes it susceptible to SQL Injection attacks.

Exploitation of this vulnerability could lead to unauthorized access to sensitive information within the Nagios XI database. Attackers might view, modify, or delete critical data, potentially impacting system integrity and confidentiality. This type of attack could also provide a pathway to further exploitation, as compromised databases often store information that can lead to further unauthorized access. Additionally, an attacker could affect the functionality of the Nagios XI application, rendering some services unreliable or unavailable.
