Patch availableDell PowerScale OneFS, versions 9.5.0.0 through 9.10.0.1, contains a missing authorization vulnerability in the NFS export. An unauthenticated attacker with remote access could potentially exploit this vulnerability leading to unauthorized filesystem access. The attacker may be able to read, modify, and delete arbitrary files. This vulnerability is considered critical as it can be leveraged to fully compromise the system. Dell recommends customers to upgrade at the earliest opportunity.

The application reaches a protected operation without first confirming that the requester is authorised.
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-862: Missing Authorization. The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
