ABB Cylon Aspect 3.08.01 (calendarFileDelete.php) Arbitrary File Deletion

Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
Firmware: <=3.08.01

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 BMS/BAS controller suffers from an arbitrary file deletion vulnerability.
Input passed to the ‘file’ parameter in calendarFileDelete.php is not properly
sanitised before being used to delete calendar files. This can be exploited by an
unauthenticated attacker to delete files with the permissions of the web server using
directory traversal sequences passed within the affected POST parameter.
