CVE-2022-20351

Local voicemail disclosure via call-log SQL injection

Published Oct 11, 2022 · Updated Aug 3, 2024

SQL injection in Android 10, 11, 12, and 12L Framework allows local users to read voicemail information through a crafted call-log query. In CallLogProvider.java, queryInternal passes the CALLS_FILTER phone-number value into SQLite without parameter binding, allowing SQL tokens to bypass voicemail permissions. A local application context is required; no additional execution privileges or user interaction is needed, and the documented consequence is limited to voicemail disclosure.
