Select Advanced and then click NAT Forwarding.If you don't know what your router IP address is, follow the instructions in this article. Enter your router's IP address (home network) as a URL in a web browser and hit Enter.Perform a search online for instructions for your specific router. The process of disabling UPnP is unique for each router. If despite the very real risks, you still wish to leave UPnP enabled, refer to the updated UPnP security specifications outlined by the Open Connectivity Framework. More details about UPnP-specific vulnerabilities can be found on the Carnegie Mellon University website. The NIST national vulnerability database can be accessed here.

Security teams should regularly refer to this list to be aware of any new patch requirements impacting existing or prospective UPnP connections.

The National Institute of Standards and Technology (NIST) hosts a continuously updated list of Common Vulnerability Exposures (CVEs) for popular devices and software solutions. This includes routers, firewalls, antivirus software, and all IoT (Internet of Things) devices that are to be connected. To prevent such infectious connections from occurring, the entire attack surface associated with a UPnP connection must be kept updated with the latest patches. Though this was about 8 years ago, UPnP-related cyberattacks are still being detected today. The U.S Department of Homeland Security urged all businesses to disable their UPnP following a cyberattack in 2013 impacting tens of millions of devices. A UPnP protocol could permit devices with critical vulnerabilities to connect to your network and sensitive resources. Though the UPnP protocol is safe, it can facilitate insecure connections. If you don't have an essential need for the UPnP feature, you should disable it. As you can see, routers are at the highest risk of being targeted in a UPnP attack. The graph below indicates the number of devices with UPnP enabled compared to the total number of analyzed devices in each category. If port forwarding is an essential requirement (if you use VoIP programs, peer-to-peer applications, game servers, etc) it's better to manually forward each port so that you have control over each established connection).īy default, most new routers come with UPnP enabled and many users are unaware that they're at risk of a malware infection or a data breach.

Modifying or terminate internal connectionsīecause it's so difficult to determine if a prospective connection could facilitate a malware infection, it's best security practice to disable UPnP.

Modifying IP settings for all interfaces.

Changing DNS server settings so that a decoy credential stealing website is loaded instead of legitimate banking websites.

Port forwarding to any external server located on either their surface or dark web.

Port forwarding the router web administration details.

Connecting internal ports to the router's external-facing side to create gateways ('poking holes') through firewalls.

Here are just a few examples of the malicious actions that are possible with UPnP: UPnP exploitation can result in more than just the connection of an infected device. With such an autonomous, and liberal, networking mechanism, it becomes clear how easy it is for the establishment of infected connections to spiral out of control. Ports are automatically forwarded to establish a connection when a UPnP request is received.

UPnP offers zero-configuration, meaning no human authentication is required to establish a connection. It only becomes dangerous when infected devices are involved. So the original intention of UPnP technology is safe. Such connections make DDoS attacks possible.īut when UPnP allows safedevices to connect, the established network is safe. The UPnP service becomes dangerous if it establishes connections with devices that are infected with malware.
