EFM ipTIME T16000M Session Validation httpcon_check_session_url improper authentication

A weakness has been identified in EFM ipTIME T16000M 14.20.2. The impacted element is the function httpcon_check_session_url of the component Session Validation Handler. This manipulation causes improper authentication. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

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.
