CVE-2020-0115

Local privilege escalation via incomplete host verification

Published Jun 10, 2020 · Updated Aug 4, 2024

Incorrect authorization in Android 8.0 through 10 allows local users to make an app the default handler for arbitrary domains. PackageManagerService.verifyIntentFiltersIfNeeded omits hosts from auto-verification when an intent filter also declares a non-web scheme, allowing those hosts to evade normal domain checks. A user-executed malicious app is required, but no further user interaction is needed; exploitation redirects matching domain intents to that app.
