Published Jun 23, 2023 · Updated Nov 7, 2024
Insecure junction handling in Dell Command | Update 4.9.0, A01 and earlier allows local users to cause permanent denial of service. A folder-creation operation fails to reject a Windows junction or mount point that redirects the operation outside its intended directory.
