CVE-2022-36869

Local file access via unguarded ContactsDumpActivity

Published Sep 9, 2022 · Updated Aug 3, 2024

Improper access control in Samsung Android Contacts Provider before 12.7.59 allows local users to access a file without permission. ContactsDumpActivity allows a low-privileged caller to reach the file without an effective permission gate, and Samsung's patch blocks access to the activity. Exploitation requires local low-privileged access to an affected Samsung Android device; the vendor reports unauthorized file access, while its CVSS assessment also records limited integrity and availability impact.
