Unauthenticated disclosure of appliance data

Published Jul 16, 2024 · Updated Nov 4, 2024

Information disclosure in the user interface of Oracle ZFS Storage Appliance Kit 8.8 allows remote attackers to read a subset of data via HTTP. The exact user-interface request and incorrect operation on untrusted input are undisclosed because Oracle does not publish detailed security analysis. Exploitation requires interaction by another person; the reported consequence is limited to unauthorized reading, with no integrity or availability impact.
