CVE-2022-28791

Local file overwrite via InstallAgent path validation

Published May 3, 2022 · Updated Aug 3, 2024

Improper input validation in InstallAgent in Samsung Galaxy Store before 4.5.41.8 allows local users to overwrite files via crafted install paths. InstallAgent accepts an attacker-controlled path and fails to prevent replacement of existing files in a specific storage location. Exploitation requires local execution on a Galaxy device and can alter files with Galaxy Store privileges, while no confidentiality or availability impact is documented.
