Remediation: No action required. The vulnerability was closed in the portal backend on Feb 20th, 2025. A workaround mitigating the impact was implemented on Jan 20th, 2025 immediately after reporting of the issue.
Product Description: Sunny Portal is an online portal for SMA customers to monitor their PV Systems
