ABB Cylon Aspect 3.08.02 (uploadDb.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
OS command injection vulnerability. This can be exploited to inject and execute
arbitrary shell commands through the contents of an uploaded .db file, which
is passed to the copyFile.sh script. Although the filename is sanitized, the
contents of the .db file are not, allowing attackers to inject malicious commands
that are executed on the server.
