<html><body><p>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.
