A buffer overflow vulnerability found in the 7788 UDP port of some Uniview products.
CVSS v3 is adopted in this vulnerability scoring（http://www.first.org/cvss/specification-document）
Base score: 8.9 (AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:L/A:H)
Temporal score: 7.7 (E:P/RL:O/RC:R)
To exploit this vulnerability, an attacker shall have access to 7788 UDP port of the device, otherwise the attack is impossible.
Please check if 7788 UDP port of the affected device is exposed directly to the Internet (WAN), which would give a potential attacker the ability to attack the device from the Internet.
For a device behind a router or a firewall, the router or the firewall will not map the vulnerable port (7788 UDP port) automatically or open it by default. So, so long as 7788 UDP port of the device is not mapped manually to the WAN, the device is not directly exposed to malicious attacks from the Internet.
Devices on the local area network (LAN) will not be directly attacked from the Internet.
Please configure your router or firewall to open a minimum set of ports to the internet (WAN) and keep only the necessary port mappings. Never set the device as the DMZ host or configure a full cone NAT.
