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.
