Base-VxFS-50 B.05.00.01 through B.05.00.02, Base-VxFS-501 B.05.01.0 through B.05.01.03, and Base-VxFS-51 B.05.10.00 through B.05.10.02 on HPE HP-UX 11iv3 with VxFS 5.0, VxFS 5.0.1, and VxFS 5.1SP1 mishandles ACL inheritance for default:class: entries, default:other: entries, and default:user: entries, which allows local users to bypass intended access restrictions by leveraging the configuration of a parent directory.

Security readout for executives and security teams

This flaw affects certain HPE HP-UX 11iv3 systems using VxFS. Directory permission inheritance can be handled incorrectly, letting a local user get access that administrators intended to block. It is mainly a concern for shared or multi-user legacy Unix environments where filesystem ACLs enforce separation. Exposure appears limited to HP-UX 11iv3 installations running the affected Base-VxFS and VxFS versions. Internet-facing exposure is not indicated; risk depends on local account access and reliance on inherited ACLs for access control. Treat this as a targeted legacy-platform risk, not a broad enterprise emergency. Prioritize if HP-UX hosts support regulated data, shared operations, or multiple local users, because the impact is failed access separation. Mitigation focus: Review the HPE advisory for vendor-confirmed fixes or workarounds.; Inventory HP-UX 11iv3 systems running VxFS 5.0, 5.0.1, or 5.1SP1.; Prioritize shared systems where local users have shell or application-level write access..
