CVE-2026-58146Network attack vector

Unauthenticated root command execution via cli_cookie injection

Published Sep 16, 2026 · Updated Sep 16, 2026

OS command injection in WNC T-Mobile 5G Box IDU before 1.1.0.651412 allows remote attackers to execute arbitrary commands as root. The /cgi-bin/portal.cgi handler concatenates the cli_cookie POST value directly into a find command without sanitization. No authentication is required, and successful injection grants root-level command execution on the router firmware.
