CVE-2018-6827: Omninova Vobot Firmware

High severity, CVSS 8.1. EPSS: 0.9% chance of exploitation in the next 30 days.

VOBOT CLOCK before 0.99.30 devices do not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information, and consequently execute arbitrary code, via a crafted certificate, as demonstrated by leveraging a hardcoded --no-check-certificate Wget option.

Affected products

• Omninova Vobot Firmware: before 0.99.30 (fixed in 0.99.30)
