CVE-2024-14002 is a local file inclusion (LFI) vulnerability categorized under CWE-98, affecting Nagios XI versions prior to 2024R1.1.4. The flaw exists in the NagVis integration component, where an authenticated user can manipulate path parameters used in PHP include or require statements. By supplying crafted path values, the attacker can cause the server to include arbitrary local files. This can lead to unauthorized disclosure of sensitive files such as configuration files, credentials, or logs residing on the host system. The vulnerability does not require elevated privileges beyond authentication, nor does it require user interaction beyond logging in. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L - low privileges), no user interaction (UI:N), and high impact on confidentiality (VC:H) with no impact on integrity or availability. Although no public exploits are known, the vulnerability poses a significant risk due to the sensitive nature of monitoring systems and the potential for information leakage. Nagios XI is widely used in enterprise and critical infrastructure environments for monitoring IT assets, making this vulnerability particularly concerning. The flaw could be leveraged by insider threats or compromised accounts to gain further insight into system configurations or credentials, potentially facilitating further attacks.

For European organizations, the impact of CVE-2024-14002 can be substantial. Nagios XI is commonly deployed in enterprise IT environments, including government, finance, energy, and telecommunications sectors across Europe. Exposure of sensitive files could lead to leakage of credentials, internal network topology, or configuration details, increasing the risk of lateral movement and targeted attacks. Confidentiality breaches could undermine compliance with GDPR and other data protection regulations, leading to legal and financial consequences. The vulnerability could also erode trust in monitoring systems, potentially delaying detection of other security incidents. Organizations relying on Nagios XI for critical infrastructure monitoring may face operational risks if attackers leverage disclosed information to disrupt services. The requirement for authentication limits the attack surface but does not eliminate risk, especially in environments with weak access controls or compromised user accounts.

1. Apply the official Nagios XI patch or upgrade to version 2024R1.1.4 or later as soon as it becomes available to remediate the vulnerability. 2. Restrict access to the Nagios XI web interface and NagVis integration to trusted networks and users using network segmentation and firewall rules. 3. Enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of compromised accounts. 4. Monitor and audit user activities within Nagios XI to detect anomalous access patterns or attempts to exploit path parameters. 5. Disable or limit NagVis integration if not required, reducing the attack surface. 6. Implement web application firewalls (WAF) with rules to detect and block suspicious path traversal or file inclusion attempts. 7. Regularly review and harden file permissions on the Nagios XI server to minimize exposure of sensitive files. 8. Conduct security awareness training for administrators and users to recognize and report suspicious activities.
