AI-suggested
Until an official patch is released, organizations should implement strict network segmentation and firewall rules to restrict access to the ZimaOS API endpoints, limiting them only to trusted administrators and systems. Employ strong authentication and authorization mechanisms to ensure only fully trusted users can interact with the API. Monitor API usage logs for suspicious delete requests or unusual path parameters. Consider deploying host-based intrusion detection systems (HIDS) to detect unauthorized file deletions or modifications in critical system directories. If feasible, downgrade to a previous unaffected version or isolate affected systems from production environments. Engage with IceWhaleTech for updates and apply patches immediately once available. Additionally, implement regular backups of critical system files and configurations to enable recovery in case of exploitation.
Description
ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.5.2-beta3, users are restricted from deleting internal system files or folders through the application interface. However, when interacting directly with the API, these restrictions can be bypassed. By altering the path parameter in the delete request, internal OS files and directories can be removed successfully. The backend processes these manipulated requests without validating whether the targeted path belongs to restricted system locations. This demonstrates improper input validation and broken access control on sensitive filesystem operations. No known public patch is available.
