CVE-2025-25276 Details

A vulnerability exists in Growatt Cloud Applications, specifically in the cloud portal versions through 3.6.0, allowing an unauthenticated attacker to hijack and potentially control other users' devices. This issue arises from an authorization bypass that enables the attacker to manipulate device settings or actions remotely.

Growatt has reported that the cloud-based vulnerabilities were patched and no user action is needed. Users are advised to update all devices to the latest firmware version when available, use strong passwords, enable multi-factor authentication where applicable, and report any security concerns to Growatt's service email. CISA also recommends minimizing network exposure for control system devices, using firewalls to isolate control system networks from business networks, and employing secure remote access methods like VPNs.
