CVE-2026-94098Public exploitNetwork attack vector

Authenticated command execution via unneutralized query string

Published Sep 21, 2026 · Updated Sep 21, 2026

Command injection in Netcore NBR200V2 1.3.241127.071246 allows remote authenticated users to execute commands via the firmware upgrade CGI endpoint. /www/cgi-bin/upgrade incorporates attacker-controlled QUERY_STRING data into a command without neutralizing command delimiters. High-privilege management access is required; successful exploitation permits arbitrary command execution affecting device data and service.
