Delta Controls enteliTOUCH 3.40.3935 Cross-Site Request Forgery (CSRF)
Vendor: Delta Controls Inc.
Product web page: https://www.deltacontrols.com
Affected version: 3.40.3935
3.40.3706
3.33.4005
Summary: enteliTOUCH - Touchscreen Building Controller. Get instant
access to the heart of your BAS. The enteliTOUCH has a 7-inch,
high-resolution display that serves as an interface to your building.
Use it as your primary interface for smaller facilities or as an
on-the-spot access point for larger systems. The intuitive,
easy-to-navigate interface gives instant access to manage your BAS.
Desc: The application interface allows users to perform certain actions
via HTTP requests without performing any validity checks to verify the
requests. This can be exploited to perform certain actions with administrative
privileges if a logged-in user visits a malicious web site.
Tested on: DELTA enteliTOUCH
