An issue was discovered on Sannce Smart HD Wifi Security Camera EAN 2 950004 595317 devices. A crash and reboot can be triggered by crafted IP traffic, as demonstrated by the Nikto vulnerability scanner. For example, sending the 111111 string to UDP port 20188 causes a reboot. To deny service for a long time period, the crafted IP traffic may be sent periodically.

CVE-2019-20464
An issue was discovered on Sannce Smart HD Wifi Security Camera EAN 2 950004 595317 devices. By default, a mobile application is used to stream over UDP. However, the device offers many more services that also enable streaming. Although the service used by the mobile application requires a password, the other streaming services do not. By initiating communication on the RTSP port, an attacker can obtain access to the video feed without authenticating.
CVE-2019-20465
An issue was discovered on Sannce Smart HD Wifi Security Camera EAN 2 950004 595317 devices. It is possible (using TELNET without a password) to control the camera’s pan/zoom/tilt functionality.
CVE-2019-20466
An issue was discovered on Sannce Smart HD Wifi Security Camera EAN 2 950004 595317 devices. A local attacker with the “default” account is capable of reading the /etc/passwd file, which contains a weakly hashed root password. By taking this hash and cracking it, the attacker can obtain root rights on the device.
CVE-2019-20467
An issue was discovered on Sannce Smart HD Wifi Security Camera EAN 2 950004 595317 devices. The device by default has a TELNET interface available (which is not advertised or functionally used, but is nevertheless available). Two backdoor accounts (root and default) exist that can be used on this interface. The usernames and passwords of the backdoor accounts are the same on all devices. Attackers can use these backdoor accounts to obtain access and execute code as root within the device.
