Summary

CVE-2024-51092 is a critical-severity OS Command Injection (CWE-78) vulnerability in Librenms Librenms. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 6% 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.

LibreNMS versions prior to 24.10.0 contain an OS command injection vulnerability tracked as CVE-2024-51092 and assigned CWE-78. The flaw resides in the index() method of AboutController.php, the update() method of SettingsController.php, and the initRrdDirectory() method of PollDevice.php, enabling remote code execution when attacker-controlled input reaches operating-system command execution paths.

An authenticated remote attacker with low privileges can supply crafted input to these controllers and achieve arbitrary code execution on the underlying host. The CVSS 9.1 score reflects network attack vector, low complexity, and changed scope, allowing confidentiality, integrity, and availability impacts that extend beyond the vulnerable application.

Public references include the GitHub Security Advisory GHSA-x645-6pf9-xwxw, which documents the affected components and the availability of a fix in version 24.10.0, along with a Metasploit module that implements the exploit.

The EPSS score rose sharply from low values to a peak of 0.7331 on 2026-05-09, the day after disclosure, before receding to the current 0.4411; this trajectory indicates that exploitation interest materialized quickly after the advisory was published.

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).
