Local file read and write via default permissions

Published Jan 30, 2024 · Updated Nov 12, 2024

Incorrect default permissions in Hitachi Storage Plug-in for VMware vCenter 04.0.0 through 04.9.2 allow local users to read and write files. The vendor identifies file and directory permission settings as the affected locus but does not disclose the specific paths or permission-setting operation. Exploitation requires low-privileged local access to the Oracle Linux backend appliance; the vendor has not bounded which file contents or operations are exposed.
