CVE-2017-18680

External-storage access via lockscreen Add User action

Published Apr 7, 2020 · Updated Aug 5, 2024

Improper access control in Samsung tablets running Android 5.0, 5.1, or 6.0 allows local users to access external-storage data. The lockscreen interface exposes the Add User action without enforcing the access boundary needed to protect another user's external-storage data. Access to the locked tablet is required, and the published record does not identify the responsible function or a narrower implementation defect.
