CVE-2022-23163

Data unavailability via insecure temporary-file directory

Published Apr 12, 2022 · Updated Sep 17, 2024

Denial of service in Dell PowerScale OneFS 8.2.x through 9.3.0.x allows local users with minimal privileges to interrupt data availability. Dell maps the flaw to creation of a temporary file in a directory with insecure permissions but does not disclose the affected component or operation. Exploitation requires local low-privilege access and can make cluster data unavailable, while confidentiality and integrity are unaffected.
