Successful exploitation of these vulnerabilities, discovered by Dan Regalado from Zingbox, 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.

A remote controlled robot, Versions 3.0.3.52164 and 3.0.3.53662 suffer from the remotely exploitable vulnerabilities. Prior versions may also be affected.

In one vulnerability, an attacker on an adjacent network could perform command injection.

CVE-2018-8866 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 8.8.

In addition, an attacker may be able to capture firmware updates through the adjacent network.

CVE-2018-8860 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 6.5.

Also, 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.

CVE-2018-17933 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 8.8.

In addition, 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.

CVE-2018-17931 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 6.8.

Also, if an attacker has access to the firmware they may be able to extract credentials.
CVE-2018-8858 is the case number assigned to this vulnerability, which has a CVSS v3 base score of 4.7.

The product sees use mainly in the communications sector on a global basis.

No known public exploits specifically target these vulnerabilities. However, an attacker with low skill level could leverage the vulnerabilities.

Vecna released a recommended update to mitigate the vulnerabilities. Vecna recommends the following update process:
• By default, VGo has automatic updates enabled so all updates are performed automatically when Internet access is available. If the VGo is powered off or in use, a message will appear on the screen asking if it can be updated when the VGo is next used.
• If a VGo unit has automatic updates turned off, the update will not be downloaded (however, a notice about the update will be displayed on the VGo’s screen). Vecna recommends that automatic updates be turned on. Select “settings” from the main menu then “advanced settings” then “automatic updates.”

Vecna released an update for CVE-2018-8858.

Vecna has not addressed CVE-2018-17931 and CVE-2018-17933.
