ABB Cylon Aspect 3.08.01 (jsonProxy.php) Unauthenticated Remote SSH Service Control


Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: <=3.08.01

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 jsonProxy.php endpoint on the ABB BMS/BAS controller is vulnerable
to unauthorized SSH service configuration changes. An unauthenticated attacker
can enable or disable the SSH service on the server by accessing the FTControlServlet
with the sshenable parameter. The jsonProxy.php script proxies requests to
localhost without enforcing authentication, allowing attackers to modify SSH
settings and potentially gain further unauthorized access to the system.

Tested on: GNU/Linux 3.15.10 (armv7l)
           GNU/Linux 3.10.0 (x86_64)
           GNU/Linux 2.6.32 (x86_64)
