Improper access control and path traversal vulnerability in LauncherProvider prior to SMR Aug-2022 Release 1 allow local attacker to access files of One UI.

Cacheservice did not correctly check if relative cache object were pointing to the defined absolute location when accessing resources. An attacker with access to the database and a local or restricted network would be able to read arbitrary local file system resources that are accessible by the services system user account. We have improved path validation and make sure that any access is contained to the defined root directory. No publicly available exploits are known.
