CVE-2025-43905Network attack vector

Authenticated service interruption via argument injection

Published Oct 7, 2025 · Updated Oct 7, 2025

Argument injection in Dell PowerProtect Data Domain DD OS allows remote authenticated users to interrupt service through crafted command input. Dell identifies improper neutralization of argument delimiters in a command but has not published the affected interface, command, or input field. Low-privileged network access is required; published evidence limits the consequence to service interruption without specifying a hang, crash, or restart.
