CVE-2019-17096Public exploitNetwork attack vector

Unauthenticated command execution via unescaped firmware URL

Published Jan 28, 2020 · Updated Sep 17, 2024

OS command injection in Bitdefender BOX 2 allows remote attackers to execute commands by impersonating a Nimbus server. The bootstrap get_image_size function concatenates the firmware URL from get_image_url into an io.popen curl command without shell escaping or validation. Reachability requires bootstrap setup and impersonation of a trusted Nimbus infrastructure server; exploitation runs arbitrary system commands on the appliance.
