Summary

CVE-2024-9054 is a high-severity OS Command Injection (CWE-78) vulnerability in Microchip Timeprovider 4100 Firmware. Its CVSS base score is 8.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 4% 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.

CVE-2024-9054 is an OS command injection vulnerability, also involving exposure of sensitive information, that affects the configuration modules of the Microchip TimeProvider 4100 grandmaster clock. The flaw stems from improper neutralization of special elements in OS commands (CWE-78) and impacts all versions from 1.0 up to but not including 2.4.7. It carries a CVSS 4.0 score of 8.5, reflecting network attack vectors with low complexity and low privileges required.

An attacker with limited privileges and the ability to supply or modify configuration files can inject arbitrary operating system commands. Successful exploitation grants the ability to execute commands on the device, potentially leading to full control over the affected TimeProvider 4100 unit and disclosure of sensitive configuration or operational data.

Vendor guidance indicates that the issue is resolved in firmware version 2.4.7 and later. Microchip has published details on responsible disclosure for this remote code execution path through configuration files, while independent analysis from Gruppo TIM's red team highlights the practical impact on deployed appliances. The associated EPSS score reached a peak of 0.3259 before receding to its current value of 0.2457.

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'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).
