Another 0-Day Looms for Many Western Digital Users

Summary: Researchers Radek Domanski and Pedro Ribeiro found a remote code execution flaw in all Western Digital NAS devices running MyCloud OS 3, an operating system Western Digital stopped supporting in 2021, and published a video in February 2021 showing how a low-privileged account with a blank password can push malicious firmware to a vulnerable device. Western Digital said the bug was already fixed by MyCloud OS 5, did not answer whether it was ever patched in OS 3, and stated it will not evaluate or support the third-party patch the researchers released.

What's compelling: Western Digital's own support page still drew enough OS 3 posts for the researcher to call the user base considerable, and OS 5 broke functionality that keeps some owners from migrating - so an unpatched remote code execution flaw sits on internet-reachable storage that may hold the only copy of a customer's data.
