Authenticated denial of service via audit condition check
Published Aug 2, 2021 · Updated Sep 16, 2024
Improper condition check in Dell PowerScale OneFS 8.1.2-9.1.0.x allows remote authenticated users to cause denial of service. The auditing component mishandles an unusual or exceptional condition, but Dell has not published the specific code path or trigger. Low-privilege authenticated access is required, and the consequence is service availability loss without reported confidentiality or integrity impact.
