CVE-2023-28078Network attack vector

Unauthenticated information disclosure and service interruption

Published Feb 15, 2024 · Updated Aug 15, 2024

Information disclosure in Dell SmartFabric OS10 10.5.2.x through 10.5.5.3 allows remote attackers to read sensitive data. Dell identifies the ZeroMQ service used when VLT is configured as the locus but has not published the faulty operation performed on untrusted requests. VLT must be configured; sending a huge number of requests can also interrupt the switch service, while no integrity impact is reported.
