Summary
HP Poly EagleEye Cube USB version 1.3.1-001267 has a command injection flaw in one API function of a management service accessible over USB. Insufficient input validation lets an attacker control part of the CSR certificate generation process (CWE-77). An attacker without administrator-level access can run arbitrary commands as root, gaining full control of the device and the ability to place a persistent backdoor that could operate over the Ethernet port.

Description from the CNA
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).
