ABB Cylon Aspect 3.08.02 Authenticated Path Traversal

The ABB Cylon controller in the version 3.08.02 and below is vulnerable to an authenticated path traversal issue. By manipulating the 'devName' POST parameter in ethernetUpdate.php script, an attacker can write partially controlled data like IP addresses to arbitrary file paths. This could potentially result in unauthorized configuration changes, system compromise, and denial of service by overwriting ethernet configuration backup files.

Mitigation:

To mitigate this vulnerability, it is recommended to update the ABB Cylon controller firmware to a version higher than 3.08.02. Additionally, restrict access to the ethernetUpdate.php script to authorized personnel only.

# Exploit Title: ABB Cylon Aspect 3.08.02 (ethernetUpdate.php) - Authenticated Path Traversal
# Vendor: ABB Ltd.
# Product web page: https://www.global.abb
# Affected version: NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, ASPECT-Studio
                  Firmware: <=3.08.02

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 ABB Cylon controller suffers from an authenticated path traversal
vulnerability. This can be exploited through the 'devName' POST parameter in
the ethernetUpdate.php script to write partially controlled content, such as
IP address values, into arbitrary file paths, potentially leading to configuration
tampering and system compromise including denial of service scenario through
ethernet configuration backup file overwrite.
