The NFS service in EMC Isilon OneFS 8.1.0.0, 8.0.1.0 - 8.0.1.1, and 8.0.0.0 - 8.0.0.4 maintains default NFS export settings (including the NFS export security flavor for authentication) that can be leveraged by current and future NFS exports. This NFS service contained a flaw that did not properly propagate changes made to the default security flavor to all new and existing NFS exports that are configured to use default NFS export settings and that are mounted after those changes are made. This flaw may potentially allow NFS clients to access affected NFS exports using the default and potentially weaker security flavor even if a more secure one was selected to be used by the OneFS administrator, aka an "NFS Export Security Setting Fallback Vulnerability."

Remediation

Which version to upgrade to

Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.

No fix version is recorded for this entry. Check the references for vendor advisories.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
