CVE-2020-5365
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDell EMC Isilon versions 8.2.2 and earlier contain a remotesupport vulnerability. The pre-configured support account, remotesupport, is bundled in the Dell EMC Isilon OneFS installation. This account is used for diagnostics and other support functions. Although the default password is different for every cluster, it is predictable.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDell EMC Isilon OneFS contains a default credential vulnerability in the pre-configured 'remotesupport' service account. Although each cluster receives a unique default password, the password generation mechanism is predictable, allowing attackers to compute valid credentials and gain unauthorized access to the support account used for diagnostics and maintenance functions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Isilon OneFS versionRun `isi version` or `isi status` from the OneFS CLI, or view the About page in the WebUI. Alternatively, use the OneFS API: GET /platform/1/aboutAffected if The installed version is OneFS 8.2.2 or lower
-
Verify remotesupport account existsRun `isi auth users | grep remotesupport` or check via WebUI in Access > Users & Roles > Users to confirm the remotesupport service account is presentAffected if The remotesupport account exists in the system
-
Check remotesupport account password statusAttempt to authenticate with the remotesupport account using known default password patterns, or review authentication logs for successful remotesupport login attempts. In OneFS CLI, check: `isi auth users remotesupport --info`Affected if The remotesupport account password has not been changed from its default generated value, or the password follows the predictable default pattern
You are affected if running Isilon OneFS version 8.2.2 or lower AND the remotesupport account exists with a password that has not been changed to a strong, non-predictable value.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImmediately change the remotesupport account password to a strong, non-predictable value following Dell EMC password guidelines, and restrict network access to management interfaces to prevent external exploitation.
