Summary
A missing or broken authorization check in the ABUP IoT Cloud Platform allowed an authenticated attacker to access device profiles, configuration data, and operational settings for which they were not authorized. The vulnerable method has been removed by the vendor as of 19 April 2025, making the specific endpoint no longer accessible. However, users should audit their account access during the exposure period and reset authentication credentials.
What this means
What could happen
An attacker with valid credentials to the ABUP IoT Cloud Platform could access device profiles and configuration data they should not be authorized to view, potentially revealing sensitive operational information about connected devices.
Who's at risk
Water and utility organizations using the ABUP IoT Cloud Platform for remote device monitoring and management are affected. This impacts anyone using the cloud platform to manage connected sensors, flow meters, pressure transmitters, or other IoT-enabled control devices across distributed sites.
How it could be exploited
An attacker authenticates to the ABUP cloud platform with legitimate credentials (from an employee, contractor, or compromised account), then exploits an authorization bypass to access device profiles and settings belonging to other users or operational areas without proper permission checks.
Prerequisites
- Valid login credentials to the ABUP IoT Cloud Platform (employee, contractor, or compromised account)
- Access to the ABUP cloud platform web interface from the operator's network
- The vulnerable API method must still be accessible (vendor stated it was removed, but users should verify)

Remediation & Mitigation
0/5
Do now
0/1WORKAROUNDReview and change authentication credentials (usernames, passwords, API keys) for all ABUP cloud platform accounts, especially accounts used during the exposure period that ended 19 April 2025
Schedule — requires maintenance window
0/1Patching may require device reboot — plan for process interruption
WORKAROUNDAudit access logs on the ABUP cloud platform for the exposure period to identify if unauthorized access occurred
Long-term hardening
0/3HARDENINGImplement network segmentation to isolate IoT devices and cloud management traffic from the main operational network using firewalls
HARDENINGRequire VPN for remote access to the ABUP cloud platform management interface; ensure VPN is patched to the latest version
HARDENINGRestrict internet-facing access to the ABUP cloud platform to only authorized management workstations and remote access gateways
