This updated advisory is a follow-up to the original advisory titled ICSA-18-114-01 Vecna VGo Robot that was published April 24, 2018, on the NCCIC/ICS-CERT website.
--------- Begin Update A Part 3 of 6 ---------
Successful exploitation of these vulnerabilities could allow an attacker to capture firmware updates through network traffic, extract credentials from the firmware, record video conversations, and may allow remote code execution with root privileges.
--------- End Update A Part 3 of 6 ---------
--------- Begin Update A Part 4 of 6 ---------
The following versions of VGo Robot, a remote controlled robot, are affected:
VGo Robot: Versions 220.127.116.11164 and 18.104.22.168662. Prior versions may also be affected.
--------- End Update A Part 4 of 6 ---------
An attacker on an adjacent network could perform command injection.
An attacker may be able to capture firmware updates through the adjacent network.
--------- Begin Update A Part 5 of 6 ---------
User accounts may be able to execute commands that are outside the scope of their privileges and within the scope of an admin account. If an attacker has access to VGo XAMPP Client credentials, they may be able to execute admin commands on the connected robot.
If an attacker has physical access to the VGo Robot they may be able to alter scripts, which may allow code execution with root privileges.
If an attacker has access to the firmware they may be able to extract credentials.
