CVE-2023-38290

System command execution via exported FQC service

Published Apr 22, 2024 · Updated Aug 2, 2024

Improper access control in Sharp ROUVO V software builds allows local users to execute shell commands with Android system privileges. The exported com.evenwell.fqc components accept Intents from an unprivileged third-party app, and FQCService executes supplied commands as the system user after FQCBroadcastReceiver crashes the app. Installing and running a local app is the only required interaction; no Android permission is required, and exploitation can grant permissions, install apps, record the screen, or wipe device data.
