CVE-2022-33703

Local privilege escalation via arbitrary activity launch

Published Jul 11, 2022 · Updated Aug 3, 2024

Improper input validation in CACertificateInfo on Samsung Mobile Devices before SMR Jul-2022 Release 1 allows attackers to start arbitrary activities. CACertificateInfo fails to validate an activity-launch request before starting the referenced Android activity; Samsung has not disclosed the affected field or validation rule. Exploitation is local, requires no privileges or user interaction, and grants execution in a more privileged activity context.
