Severity
4.3
Infoleak
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N

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.
