Command Injection in HP Poly EagleEye Cube USB

Publication date: 2026-11-04

Last updated on: 2026-11-04

Assigner: MITRE

Description
On HP Poly EagleEye Cube USB 1.3.1-001267 devices, one of the API functions available on a management service accessible via USB allows command injection. This allows attackers (without administrator-level access) to execute arbitrary commands on the device as root. This is due to insufficient input validation that allows an attacker to control part of the CSR certificate generation process. This provides full root access that permits full control over device operations, unauthorized access to data, and the ability to place a persistent backdoor on the device (which could operate via the Ethernet port).

Executive Summary

CVE-2026-39431 is a command injection vulnerability in HP Poly EagleEye Cube USB devices running version 1.3.1-001267. It exists in a management service API accessible via USB where insufficient input validation allows attackers without admin access to execute arbitrary commands as root. The flaw stems from uncontrolled input during CSR certificate generation.

Detection Guidance

Detection requires checking if your HP Poly EagleEye Cube USB device is running version 1.3.1-001267. Inspect the device firmware version via the management interface or USB API. No specific commands are provided in the context, but monitoring for unusual network activity or unauthorized root-level processes may indicate exploitation.

Impact Analysis

This vulnerability allows attackers to gain full root access to the device. This could lead to unauthorized control over device operations, access to sensitive data stored on the device, and the ability to install persistent backdoors that may communicate via the Ethernet port.

Mitigation Strategies

Immediately update the HP Poly EagleEye Cube USB firmware to a patched version if available. Isolate the device from critical networks to prevent lateral movement. Disable unnecessary USB management services and restrict physical access to the device.
