CVE-2024-20829Network attack vector

Application launch via improperly gated deep links

Published Mar 5, 2024 · Updated Aug 1, 2024

Improper interaction handling in Samsung Internet before 24.0.0.0 allows remote attackers to open an application through a deep link. The deep-link handler launches the target application without obtaining the proper user interaction enforced by the patched flow. Reaching the vulnerable path requires user interaction, and the documented consequence is limited to launching an application.
