Synopsis
It was possible to add port redirections to the remote router.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 add '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.See Also
