CVE-2019-15622

Protected-table disclosure via unsanitized custom queries

Published Feb 4, 2020 · Updated Aug 5, 2024

SQL injection in Nextcloud Android app 3.6.0 allows physically proximate attackers to read content information from protected tables. Its content-provider query handling passes insufficiently sanitized custom query input to SQLite, allowing references to cross protected-table boundaries. A malicious application on the same Android device can invoke the query interface without authentication; the documented consequence is read-only disclosure.
