Vulnerability Discussion
Users' home directories/folders may contain information of a sensitive nature. Non-privileged users should coordinate any sharing of information with an SA through shared resources.
Check
Verify the operating system limits the ability of non-privileged users to grant other users direct access to the contents of their home directories/folders. If it does not, this is a finding.
Fix
Configure the operating system to limit the ability of non-privileged users to grant other users direct access to the contents of their home directories/folders.
