CVE-2025-55423: Iptime A104r Firmware code injection (CVSS 9.8)

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.

How Secuno handles this

Secuno correlates vulnerabilities like CVE-2025-55423 against the real software inventory on every managed device, as each hourly inventory arrives. Rather than a static severity, each match is scored in context: exploit availability, EPSS, the asset's exposure, and business criticality decide where it lands in the queue. If an affected version is present anywhere across your portfolio, it surfaces automatically with a prioritised remediation path.
