ABB Cylon Aspect 3.08.01 jsonProxy.php Unauthenticated Project Download

ABB Cylon Aspect 3.08.01 (jsonProxy.php) Unauthenticated Project Download

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 project file disclosure. An unauthenticated remote attacker
can issue a GET request abusing the DownloadProject servlet to download
sensitive project files. The jsonProxy.php script bypasses authentication
by proxying requests to localhost (AspectFT Automation Application Server),
granting remote attackers unauthorized access to internal Java servlets.
This exposes potentially sensitive project data and configuration details
without requiring authentication.
