CVE-2023-25940

System takeover via unsafe link following

Published Apr 4, 2023 · Updated Feb 11, 2025

Improper link resolution in isi_gather_info in Dell PowerScale OneFS 9.5.0.0 allows local users with high privileges to take over the system. The utility follows a filesystem link before accessing its target, but Dell has not disclosed the affected path handling or attacker-controlled input. Exploitation requires high privileges on a compliance-mode cluster and can compromise the system and invalidate compliance-mode guarantees.
