How you would hack a router firewall outside of your network if all. Can a hacker hack an internet router firewall knowing. How is the WAN port in a WiFi router. SG Ports Services and Protocols - Port 5353 tcp/udp information, official and unofficial assignments, known security risks, trojans and applications use. If a router has port 5060 open. Port 5353 tcp/udp. The final hit to port 53413 was dropped and appears to be a Netis router hack so unless your router is.

UPnP IGD profile The UPnP Internet Gateway Device (IGD) profile is implemented on many routers and broadband cable or ADSL modems. The profile has a few subprofiles.

Many of these profiles are nothing more than containers for one or more other subprofiles. When it comes to security there are a few profiles that are interesting: • LANHostConfigManagement • WANIPConnection/WANPPPConnection The LANHostConfigManagement profile allows a program to query and possibly set various configuration parameters for, for example, DNS, DHCP and others. The WANIPConnection and WANPPPConnection profiles allow programs to adapt firewall rules, amongst other things.

LANHostConfigManagement The LANHostConfigManagement profile enables programs to query and set local settings of a router, such as DNS and DHCP. The profile defines a few methods that are interesting methods for an attacker: • SetDNSServer • DeleteDNSServer • SetIPRouter • DeleteIPRouter These methods should allow an attacker to completely rewire a router networkwise. Accordig to the standard they are required to implement. However, in practice these methods are either not implemented, return an error when they are invoked or UPnP and DNS/DHCP/routing are not coupled to the UPnP system. It never hurts to check though. WANIPConnection/WANPPPConnection Programs such as Live Messenger, Windows remote assistance, X-Box live, various networked consoles and games and quite a few Bittorrent clients use actions that are defined in the IGD subprofiles WANPPPConnection (ADSL modems) and WANIPConnection (IP routers) to make it easier to use the network. With these actions the IGD profile works around a fundamental problem of Network Address Translation (NAT): you can't use a predefined port easily anymore if you use NAT.

If more than one program needs that port, unless you use something like a proxy. To give an example, say that Live Messenger would have a fixed port for file transfers. If you are behind NAT with a few people, who all want to transfer files with Live Messenger at the same time you have a problem.

This is why many programs dynamically allocate a port to avoid conflicts with other programs. To achieve this the programs make use of the following actions that are available in the UPnP IGD profile: • AddPortMapping:: adds a portmapping to your firewall configuration • DeletePortMapping:: removes an existing portmapping These actions are implemented as SOAP requests, as explained elsewhere. A well behaved program first asks for a portmapping and deletes the portmapping when it is not needed anymore. Many UPnP stacks have only been tested with programs that behave well, so many bugs go unnoticed. The rest of this page explains where and why the software goes wrong. AddPortMapping The AddPortMapping SOAP command is the command with which a client on a network can request that the firewall opens a specific port and forwards it to the client. The parameters for the command are: • NewRemoteHost • NewExternalPort • NewProtocol • NewInternalPort • NewInternalClient • NewEnabled • NewPortMappingDescription • NewLeaseDuration The NewRemoteHost parameter can be used to restrict the port mapping for just one external host, but in practice is never used.

The NewExternalPort parameter is used to specify the TCP or UDP port on the WAN side of the router which should be forwarded. This parameter cannot be left empty, otherwise an error is returned, because the command does not make any sense anymore. The NewProtocol parameter can take two values: UDP or TCP. The NewInternalPort parameter specifies the port on a client machine to which all traffic coming in on NewExternalPort for the protocol specified by NewProtocol should be forwarded to. The NewInternalClient parameter sets the client machine that traffic should be sent to. The NewEnabled parameter tells the router if the portmapping should be enabled. In practice this is always set to True.

The NewPortMappingDescription parameter is a human readable string that describes the connection. It is used in sorme web interfaces of routers so the user can see which program is using what port.

The last parameter is NewLeaseDuration which tells the router how long the portmapping should be active. Since most programs don't know this in advance, it is often set to 0, which means 'unlimited'. DeletePortMapping The DeletePortMapping SOAP command takes three parameters: • NewRemoteHost • NewExternalPort • NewProtocol The three parameters describe a portmapping that should be deleted.

Protocol dumbness The specifications for the IGD profile allow any control point ot use AddPortMapping to forward ports to other machines on the LAN. While it can be convenient, it is really easy this way to open file servers, printers and other machines/devices to the outside world. A fairly solution would be to not allow a control point to ask for port forwards for another IP address except its own.
