Privileged action execution via intent redirection
Published Apr 9, 2021 · Updated Aug 3, 2024
Intent redirection in Samsung Experience Service on affected Android 9 and Android 10 devices allows local users to execute privileged actions. Samsung has not disclosed which intent-handling component redirects the attacker-controlled intent or which validation is missing. The action can expose limited information, and exploitation requires an attacker-controlled app installed on the device plus user interaction.
