CRITICAL 9.8

DescriptionCVE.org

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.

AnalysisAI

Multiple ipTIME router models have a command injection vulnerability in the upnp_relay() function, allowing remote attackers to execute arbitrary OS commands through crafted UPnP requests.

Technical ContextAI

The upnp_relay() function in multiple ipTIME routers fails to sanitize UPnP control messages (CWE-94), allowing attackers to inject OS commands through crafted UPnP requests processed by the router.

RemediationAI

Update router firmware. Disable UPnP if not needed. ipTIME routers should be checked for firmware updates regularly.
