Exploit Code

ABB Cylon Aspect 3.08.03 (MIX->HTTPDownloadServlet) File Deletion

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 BMS/BAS is vulnerable to a critical flaw in the

AuthenticatedHttpServlet within its application server, enabling

remote attackers to bypass authentication by setting the Host:

127.0.0.1 header. This deceives the server into processing requests

as if they originate from localhost, granting unauthorized access

to privileged operations. This bypass grants access to privileged

functionality, including the HTTPDownloadServlet, which is vulnerable

to directory traversal. By leveraging this, an attacker can delete

arbitrary PHP files outside the intended directory scope.
