A device API endpoint was missing access controls on Western Digital My Cloud OS 5 iOS and Anroid Mobile Apps, My Cloud Home iOS and Android Mobile Apps, SanDisk ibi iOS and Android Mobile Apps, My Cloud OS 5 Web App, My Cloud Home Web App and the SanDisk ibi Web App. Due to a permissive CORS policy and missing authentication requirement for private IPs, a remote attacker on the same network as the device could obtain device information by convincing a victim user to visit an attacker-controlled server and issue a cross-site request.
This issue affects My Cloud OS 5 Mobile App: before 4.21.0; My Cloud Home Mobile App: before 4.21.0; ibi Mobile App: before 4.21.0; My Cloud OS 5 Web App: before 4.26.0-6126; My Cloud Home Web App: before 4.26.0-6126; ibi Web App: before 4.26.0-6126.

Assuming a user with a given identity, authorization is the process of determining whether that user can access a given resource, based on the user’s privileges and any permissions or other access-control specifications that apply to the resource. When access control checks are not applied, users are able to access data or perform actions that they should not be allowed to perform. This can lead to a wide range of problems, including information exposures, denial of service, and arbitrary code execution.
