CVE-2023-32470

Permanent denial of service via junction handling

Published Sep 8, 2023 · Updated Sep 25, 2024

Insecure junction handling in Dell Digital Delivery before 5.0.82.0 allows local users to cause permanent denial of service. The affected installation operation fails to reject a folder path redirected through a Windows junction or mount point, causing the service to create a folder outside its intended location. Exploitation requires low-privileged local access and user interaction; Dell reports availability loss only and does not disclose recovery details.
