CVE-2026-58147: Authorized remote code execution via password change functionality in T-Mobile 5G Box IDU routers

Noroxi assessment

Priority: Monitor (action score 37/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 1.5% (FIRST EPSS); higher than 75.3% of all records.
Someone on the same network segment can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

WNC T-Mobile 5G Box IDU router contains an OS command injection vulnerability in the portal.cgi component's password change functionality. The application improperly neutralizes special elements in the http_passwd_hidden and http_passwdConfirm_hidden parameters, allowing an authenticated attacker to execute arbitrary commands on the underlying operating system with root privileges.This issue has been fixed in firmware version 1.1.0.651412
