Last modified
CVE-2025-55423 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 3.33% chance of exploitation in the next 30 days.
Description
