Summary

The Meari IoT Cloud Platform OpenAPI Service contains authorization flaws (CWE-862) that allow authenticated users to manipulate device configurations and access sensitive information including device credentials, owner details, and network data beyond their intended scope. Meari did not respond to CISA coordination attempts and has not released a patch for all versions.

What this means
What could happen
An attacker with valid credentials could modify device configurations and access sensitive data like device credentials and network information, potentially compromising the security of connected IoT devices and the broader network they serve.
Who's at risk
Organizations using Meari IoT Cloud Platform OpenAPI Service for device management and monitoring, including water utilities, electric utilities, and other facilities that depend on IoT devices for operational visibility or control. This affects anyone relying on the cloud platform to manage connected IoT sensors or devices in their infrastructure.
How it could be exploited
An attacker with valid user credentials could use the OpenAPI service to make unauthorized changes to device settings or extract sensitive configuration and credential data. No special exploit code or advanced techniques are required—the attacker simply needs legitimate login credentials and network access to the API endpoint.
Prerequisites
  • Valid user credentials for the IoT Cloud Platform OpenAPI Service
  • Network access to the OpenAPI endpoint
  • Knowledge of API endpoints for device configuration and data retrieval

WORKAROUNDContact Meari directly for security guidance and any available mitigations since the vendor has not released a patch
HARDENINGRestrict network access to the OpenAPI endpoint to trusted users and networks only; implement firewall rules to limit API connectivity
HARDENINGEnforce strong, unique passwords for all OpenAPI service accounts and implement multi-factor authentication if available
Schedule — requires maintenance window
0/2

Patching may require device reboot — plan for process interruption

HARDENINGMonitor API activity logs for unauthorized configuration changes or credential access attempts
WORKAROUNDEvaluate whether the IoT Cloud Platform OpenAPI Service is necessary for your operations; consider removing or disabling it if not actively used
