Summary

CVE-2025-34280 is a high-severity OS Command Injection (CWE-78) vulnerability in Nagios Network Analyzer. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 31% 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.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Nagios Network Analyzer versions prior to 2024R2.0.1 contain an OS command injection vulnerability in the LDAP certificate management functionality. The certificate removal operation lacks adequate input sanitization, allowing improper data to reach system commands executed by the web application service.

An authenticated administrator can supply crafted input during certificate removal to execute arbitrary commands on the underlying host. This grants remote code execution with the privileges of the web application service, affecting confidentiality, integrity, and availability on the server.

Nagios advisory information and the associated changelog indicate that upgrading to version 2024R2.0.1 resolves the issue by correcting the input handling in the LDAP certificate removal path. The referenced VulnCheck advisory further documents the affected component and the required update.

The EPSS score remains flat at 0.0105 with no material increase observed after disclosure.

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
prevents

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).
