CVE-2024-14002 is a local file inclusion vulnerability affecting Nagios XI versions prior to 2024R1.1.4, specifically through its NagVis integration component. The vulnerability arises from improper control of filename input used in PHP include or require statements (CWE-98). An authenticated user with low privileges can manipulate path parameters to cause the server to include arbitrary local files. This can lead to disclosure of sensitive files such as configuration files, credentials, or other sensitive data residing on the host. The vulnerability is remotely exploitable over the network without requiring user interaction beyond authentication, which lowers the barrier for exploitation within an organization. The CVSS v4.0 score of 7.1 reflects a high severity, driven by network attack vector, low attack complexity, no user interaction, and high impact on confidentiality. Although no public exploits have been reported yet, the nature of LFI vulnerabilities often leads to further exploitation such as privilege escalation or remote code execution if chained with other vulnerabilities. Nagios XI is widely used for IT infrastructure monitoring, making this vulnerability particularly concerning for organizations relying on it for operational visibility. The lack of a patch link in the provided data suggests that organizations should verify the availability of updates from Nagios and apply them promptly. Additionally, the NagVis integration should be carefully monitored and access restricted to trusted users only.

For European organizations, the impact of CVE-2024-14002 can be significant due to the widespread use of Nagios XI in critical infrastructure, government, finance, and large enterprises. Exposure of sensitive configuration files or credentials could lead to further compromise of monitoring systems and underlying infrastructure. This could disrupt IT operations, reduce visibility into network health, and potentially enable attackers to move laterally within networks. Confidentiality breaches could also lead to regulatory non-compliance under GDPR if personal or sensitive data is exposed. The vulnerability’s ease of exploitation by authenticated users increases the risk from insider threats or compromised credentials. Organizations with complex IT environments relying heavily on Nagios XI for monitoring are particularly vulnerable to operational disruptions and data leaks. The potential for chained attacks elevates the risk profile, making timely remediation critical to maintaining security posture and operational continuity.

1. Upgrade Nagios XI to version 2024R1.1.4 or later as soon as the patch is available from the vendor to address the vulnerability directly. 2. Restrict access to the NagVis integration interface to only trusted and necessary users, ideally via network segmentation and VPNs. 3. Implement strict input validation and sanitization on all user-supplied path parameters within Nagios XI and NagVis components to prevent malicious path traversal or inclusion attempts. 4. Deploy Web Application Firewalls (WAF) with rules targeting LFI attack patterns to detect and block suspicious requests. 5. Monitor authentication logs and access patterns for unusual activity that could indicate exploitation attempts. 6. Conduct regular security audits and penetration testing focused on Nagios XI and its integrations to identify and remediate similar vulnerabilities proactively. 7. Educate administrators and users about the risks of credential compromise and enforce strong authentication mechanisms such as multi-factor authentication (MFA).
