Summary: WebCTRLA(r), 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.  
  
Desc: 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.
