CVE-2018-1239
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 Unity Operating Environment (OE) versions prior to 4.3.0.1522077968 are affected by multiple OS command injection vulnerabilities. A remote application admin user could potentially exploit the vulnerabilities to execute arbitrary OS commands as system root on the system where Dell EMC Unity is installed.
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 Unity Operating Environment versions prior to 4.3.0.1522077968 contain multiple OS command injection vulnerabilities. A remote authenticated application administrator can exploit these flaws to execute arbitrary operating system commands with root privileges on the underlying Unity system.

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.
-
Identify the installed Dell EMC Unity product typeAccess the Unity Unisphere web interface and navigate to the System > Settings > General page, or run the 'svc_info -t' command from the service CLI to determine if the system is Unity Operating Environment or Unityvsa Operating EnvironmentAffected if The product is Dell EMC Unity Operating Environment or Dell EMC Unityvsa Operating Environment
-
Check the installed OE versionIn Unisphere, go to Settings > Support > About or execute 'version' command in the service CLI to retrieve the full version string. Compare it numerically to 4.3.0.1522077968Affected if The installed version string is less than 4.3.0.1522077968 (any build prior to this release)
-
Verify application administrator service statusIn Unisphere, navigate to Administration > User Management > Users and confirm whether any user is assigned the Application Administrator role, or check if the Application API service (port 443) is listening and accessible from network segmentsAffected if Application Administrator users exist and the application API service is accessible from the network
-
Check remote access configurationFrom the service CLI, run 'svc_config network' or review the Unisphere access settings under Settings > Access > Management to determine if remote application administrator access is permittedAffected if Remote access to the application administrator interface is enabled
The environment is affected if it runs Dell EMC Unity Operating Environment or Unityvsa with a version prior to 4.3.0.1522077968 and has application administrator access enabled for authenticated 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 data4.3.0.1522077968
Upgrade Dell EMC Unity OE to version 4.3.0.1522077968 or later to patch the command injection vulnerabilities. Prior to upgrade, restrict application admin access and monitor for suspicious command execution.
