CVE-2026-58146

Unauthorized remote code execution in T-Mobile 5G Box IDU routers

Published Sep 16, 2026 CVSS 4.0 · 9.4 Critical EPSS 2.9% KEV · Not listed
Description
WNC T-Mobile 5G Box IDU router is vulnerable to OS command injection vulnerability. The vulnerability exists within the /cgi-bin/portal.cgi endpoint, specifically through the cli_cookie POST parameter. The cli_cookie parameter value is directly concatenated into a find command string without proper sanitization. This allows a remote, unauthenticated attacker to inject and execute arbitrary shell commands as root on the underlying operating system.

This issue has been fixed in firmware version 1.1.0.651412
