ABB Cylon Aspect 3.08.03 (MIX->IPConfigServlet) Network Manipulation


Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: <=3.08.03

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: ABB Cylon Aspect MIX's IPConfigServlet allows unauthenticated network
config changes via the Host: 127.0.0.1 bypass, writing to /etc/hosts and
config files. Attackers can redirect traffic (e.g. localhost to 1.2.3.4)
or disrupt connectivity, amplifying impact with network restarts.
