Local information disclosure via exported content provider
Published Feb 13, 2023 · Updated Mar 10, 2025
SQL injection in ownCloud Android App 3.0 and earlier allows local users to read internal database data through its content provider. The exported FileContentProvider passes attacker-controlled selection and where values into SQLite operations without sanitization, enabling blind queries against owncloud_database. A malicious application on the same Android device needs no special permission and can disclose data from room_master_table and folder_backup.
