CVE-2026-94099Public exploitNetwork attack vector

Authenticated command execution via restore.cgi query string

Published Sep 21, 2026 · Updated Sep 21, 2026

Command injection in NBR200V2 1.3.241127.071246 allows remote authenticated users to execute commands through the Backup Restore interface. The restore.cgi endpoint processes an attacker-controlled QUERY_STRING as command input without neutralizing special command elements. Low-privileged management access is required; successful injection executes commands in the appliance context and can alter data or interrupt routing.
