CVE-2021-36340
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 SCG 5.00.00.10 and earlier, contain a sensitive information disclosure vulnerability. A local malicious user may exploit this vulnerability to read sensitive information and use it.
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 · low confidenceDell EMC SCG versions 5.00.00.10 and earlier contain a local information disclosure vulnerability where a malicious user with local access can read sensitive information. The CVSS 5.5 score indicates a medium-severity issue with local attack vector and low privileges required.

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.
-
Confirm Dell SCG product is installedIdentify if the system is running Dell Secure Connect Gateway (SCG) or Dell EMC SCG. Check system inventory, installed software, or product documentation for the presence of this Dell storage or gateway product.Affected if Dell Secure Connect Gateway or Dell EMC SCG is present on the system
-
Check installed SCG versionLocate the installed version of Dell SCG. This is typically found in the product's about page, version information in the management interface, or via command line tools provided by the product. Common locations include the web UI header, CLI 'version' command, or system information files.Affected if Version is 5.00.00.10 or earlier, specifically including version 3.52.10.08 or version 5.00.00.10
-
Verify local access exposureAssess whether untrusted users could potentially gain local (physical or terminal) access to the SCG system. Check physical security controls and logical access restrictions on the server hosting SCG.Affected if Local (physical or console) access to the SCG system is available to users other than trusted administrators
You are affected if Dell Secure Connect Gateway or Dell EMC SCG is installed with version 5.00.00.10 or earlier (including 3.52.10.08) and the system has local access exposure to untrusted users.

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 dataApply the vendor patch or upgrade to a version newer than 5.00.00.10. If no patch is available, restrict physical and logical access to the SCG system to trusted administrators only.
