Summary

CVE-2024-14003 is a critical-severity OS Command Injection (CWE-78) vulnerability in Nagios Nagios Xi. Its CVSS base score is 9.4 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 20% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

CVE-2024-2024-14003 is a remote code execution (RCE) vulnerability in Nagios XI versions prior to 2024R1.2, stemming from insufficient validation of inbound NRDP (Nagios Remote Data Processor) request parameters in its server plugins. This flaw, classified as CWE-78 (OS Command Injection), allows crafted input to reach command execution paths, enabling arbitrary command execution on the underlying host in the context of the web/Nagios service. The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its network accessibility and lack of prerequisites.

An unauthenticated attacker with network access to the NRDP service can exploit this vulnerability by submitting specially crafted NRDP requests. Successful exploitation grants remote command execution as the web/Nagios service user, potentially allowing full compromise of the host system, including data exfiltration, persistence, or lateral movement.

Nagios advisories address this issue through patches in version 2024R1.2 and later. Additional mitigation details are available in the Nagios XI changelog at https://www.nagios.com/changelog/nagios-xi/, the security products page at https://www.nagios.com/products/security/#nagios-xi, and the VulnCheck advisory at https://www.vulncheck.com/advisories/nagios-xi-rce-via-nrdp-server-plugins.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
