AI-suggested
Immediate mitigation steps should include restricting the 'plant transfer' functionality to only highly trusted and verified accounts with multi-factor authentication (MFA) enforced. Growatt administrators should implement strict authorization checks ensuring that only authorized personnel can initiate plant transfers, ideally incorporating role-based access control (RBAC) and transaction approval workflows. Monitoring and logging of all plant transfer requests should be enhanced to detect anomalous or unauthorized activities promptly. Organizations should conduct an audit of existing plant ownership records to identify any unauthorized transfers and revert them if necessary. Until an official patch is released, network-level controls such as Web Application Firewalls (WAFs) can be configured to detect and block suspicious requests targeting the plant transfer endpoint. User education on account security and immediate revocation of compromised credentials are also critical. European organizations should engage with Growatt for timely updates and consider isolating critical energy management systems from direct internet exposure where feasible.
Description
An incorrect authorisation check in the the 'plant transfer' function of the Growatt cloud service allowed a malicous attacker with a valid account to transfer any plant into his/her account.
