Vulnerability
[ Description ]Official 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).
