Security readout for executives and security teams
Plain-English summary
This flaw affects Dell EMC PowerScale OneFS 8.2.x through 9.2.x. A user who can log in by SSH or console with the named OneFS privilege may see privileged cluster information because a critical resource has incorrect permissions. The issue is high severity, but the published vector indicates local access and high attack complexity.
Executive priority
Treat this as a high-priority storage infrastructure issue where affected OneFS versions and delegated login privileges overlap. It is not supported by provided evidence as internet-remote or actively exploited, but the potential cluster impact is significant.
Technical view
CVE-2021-36280 is CWE-732 in Dell EMC PowerScale OneFS 8.2.x-9.2.x. The CVSS 3.1 vector is AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H, scoring 7.8. The source description ties access to ISI_PRIV_LOGIN_SSH or ISI_PRIV_LOGIN_CONSOLE and privileged cluster information exposure.
Likely exposure
Organizations may be exposed if they run Dell EMC PowerScale OneFS 8.2.x through 9.2.x and grant SSH or console login privileges to non-administrative or broadly assigned users.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation evidence. The CVSS vector describes a local, authenticated path requiring low privileges, no user interaction, and high attack complexity.
Researcher notes
Evidence is limited to the CVE description, CVSS data, CWE-732, affected version range, and Dell advisory URL. The bundle does not provide fixed versions, exploit details, or named workarounds, so remediation should be verified directly against Dell guidance.
Mitigation direction
- Identify PowerScale clusters running OneFS 8.2.x through 9.2.x.
- Review Dell advisory 000190408 for supported fixes or workarounds.
- Restrict ISI_PRIV_LOGIN_SSH and ISI_PRIV_LOGIN_CONSOLE to necessary administrators.
- Audit privileged cluster information access by SSH and console users.
- Prioritize remediation where login privileges are broadly delegated.
Validation and detection
- Inventory OneFS versions across all PowerScale clusters.
- List users and roles with ISI_PRIV_LOGIN_SSH or ISI_PRIV_LOGIN_CONSOLE.
- Check whether Dell advisory remediation has been applied.
- Review logs for unusual SSH or console access to cluster information.
- Confirm least-privilege access after remediation.
