CVE-2023-28055

Unauthenticated server file compromise via command manipulation

Published Sep 26, 2023 · Updated Sep 24, 2024

Improper authorization in affected Dell Technologies NetWorker NW Client 19.7, 19.8, and 19.9 releases allows remote attackers to compromise server files. The client accepts a manipulated command for its remote server-file modification capability without enforcing the required authorization. Same-network, unauthenticated access is sufficient to read or alter server files, interrupt service, and execute arbitrary code.
