CVE-2026-58146

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

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
