CVE-2021-0358

Local privilege escalation via netdiag command injection

Published Feb 2, 2021 · Updated Aug 3, 2024

Command injection in Android netdiag on Android 10 and Android 11 allows local users with System privileges to escalate privileges. Netdiag improperly validates input before using it in command execution, allowing injected commands to run in the System context without user interaction. Exploitation requires existing local System-level execution privileges; the documented consequence is privilege escalation with confidentiality, integrity, and availability impact.
