CVE-2023-25540

Denial of service via incorrect security_check permissions

Published Feb 28, 2023 · Updated Mar 11, 2025

Incorrect default permissions in Dell PowerScale OneFS 9.4.0.0 through 9.4.0.11 allow local users to overwrite arbitrary files. The /ifs/.ifsvar/modules/security_check directory receives permissions that are not restrictive enough, allowing writes outside its intended access boundary. High local privileges are required, and successful exploitation can interrupt service through file corruption.
