CVE-2023-24576Network attack vector

Unauthenticated code execution via nsrdump option

Published Feb 3, 2023 · Updated Mar 25, 2025

Code injection in NetWorker Virtual Edition allows remote attackers to execute code through unauthenticated nsrexecd RPC requests. The service accepts a remote request that invokes nsrdump with its -M option without enforcing NetWorker authentication. Dell has not disclosed the option's input-handling defect, and its current impact assessment limits the demonstrated consequence to reading data.
