This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical Description

A command injection vulnerability exists in the upnp_relay() function in multiple ipTIME router models because the controlURL value used to pass port-forwarding information to an upper router is passed to system() without proper validation or sanitization, allowing OS command injection.

Remediation

Check the references section for vendor advisories and patches from iptime. Update n104s-r1_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
