CVE-2021-43588Network attack vector

Service interruption via undisclosed malformed input

Published Jan 24, 2022 · Updated Sep 16, 2024

Improper input validation in Dell Data Protection Central before 19.6 allows remote authenticated users to interrupt service. Dell has not published the affected request, input field, validation routine, or malformed value that triggers the condition. Exploitation is network-reachable and causes limited availability loss; Dell's privileges-required metric indicates low privileges despite advisory text describing unauthenticated access.
