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.

Analysis

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 Context

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.

Affected Products

['Multiple ipTIME router models']

Remediation

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