UPnP Internet Gateway Device (IGD) Port Mapping Listing

Medium Nessus Plugin ID 94048

Synopsis

It was possible to list the port mappings created via UPnP IGD on the remote device.

Description

According to its UPnP data, the remote device is a NAT router that supports the Internet Gateway Device (IGD) Standardized Device Control Protocol. Nessus was able to list 'port mappings' that redirect ports from the device's external interface to the scanner address.

An unauthenticated, remote attacker can exploit this issue (e.g., via JavaScript or a malicious Flash animation) to open holes in the device's firewall. An unauthenticated, adjacent attacker has unrestricted access to this interface.

Solution

Disable IGD or restrict access to trusted networks.
