CVE-2023-28053Network attack vector

Information disclosure via deprecated SSH algorithms

Published Dec 18, 2023 · Updated Aug 2, 2024

Cryptographic weakness in affected Dell NetWorker Virtual Edition releases allows remote attackers to disclose information through SSH. The appliance's SSH component negotiates deprecated cryptographic algorithms, but Dell has not identified the algorithms or disclosed how they expose data. The SSH service must be network-reachable; exploitation requires no authentication or user interaction, and the documented impact is limited to information disclosure.
