ABB Cylon Aspect 3.07.02 – File Disclosure

The ABB Cylon Aspect 3.07.02 product is prone to an authenticated arbitrary file disclosure vulnerability. This vulnerability exists in the 'downloadDb.php' script due to improper validation of user-supplied input in the 'file' GET parameter. Attackers can exploit this issue to read sensitive files by traversing directories.

Mitigation:

To mitigate this vulnerability, restrict access to the affected script and ensure that user input is properly validated and sanitized before use.

# Exploit Title : ABB Cylon Aspect 3.07.02 - 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.
