CVE-2019-3704
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 · uneditedVNX Control Station in Dell EMC VNX2 OE for File versions prior to 8.1.9.236 contains OS command injection vulnerability. Due to inadequate restriction configured in sudores, a local authenticated malicious user could potentially execute arbitrary OS commands as root by exploiting this vulnerability.
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 confidenceLocal privilege escalation vulnerability in Dell EMC VNX2 Control Station where improper sudoers configuration allows an authenticated local user to execute arbitrary OS commands as root through command injection.

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 VNX2 firmware versionAccess the Control Station and run the command to display the installed VNX2 OE for File firmware version (typically via 'navicli -getversion' or system management interface)Affected if The installed version is below 8.1.9.217
-
Locate sudoers configuration fileView the sudoers file on the Control Station (typically /etc/sudoers or files in /etc/sudoers.d/) using 'visudo' or 'cat' with appropriate permissionsAffected if A sudoers entry allows a local authenticated user to run specific commands without password prompt that can be manipulated for command injection
-
Identify overly permissive sudo command allowancesReview sudoers entries for commands that accept user-supplied input or allow shell escape sequences, particularly any custom scripts or utilities listed with ALL or broad path specificationsAffected if A sudoers rule permits execution of commands that can be exploited for command injection to achieve root privileges
-
Test for command injection vectorIf a vulnerable sudoers entry is found for a command or script, attempt to inject OS commands through its parameters (for example, using ';' or '|' shell metacharacters) while executing via sudoAffected if The sudo-enabled command permits arbitrary OS command execution as root when supplied with shell metacharacters
A user is affected if their VNX2 firmware version is below 8.1.9.217 AND the Control Station sudoers configuration contains overly permissive command allowances that can be exploited for privilege escalation.

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 data8.1.9.217
Upgrade VNX2 OE for File to version 8.1.9.236 or later, and audit sudoers configuration to remove overly permissive command allowances.
