Automated Logic WebCTRL 6.1 Path Traversal Arbitrary File Write

Title: Automated Logic WebCTRL 6.1 Path Traversal Arbitrary File Write
Advisory ID: ZSL-2017-5430
Type: Local/Remote
Impact: Manipulation of Data, DoS
Risk: (3/5)
Release Date: 22.08.2017
WebCTRL®, Automated Logic's web-based building automation system, is known for its intuitive user interface and powerful integration capabilities. It allows building operators to optimize and manage all of their building systems - including HVAC, lighting, fire, elevators, and security - all within a single HVAC controls platform. It's everything they need to keep occupants comfortable, manage energy conservation measures, identify key operational problems, and validate the results.
The vulnerability is triggered by an authenticated user that can use the manualcommand console in the management panel of the affected application. The ManualCommand() function in ManualCommand.js allows users to perform additional diagnostics and settings overview by using pre-defined set of commands. This can be exploited by using the echo command to write and/or overwrite arbitrary files on the system including directory traversal throughout the system.
