CVE-2018-20713
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 · uneditedShopware before 5.4.3 allows SQL Injection by remote authenticated users, aka SW-21404.
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 confidenceSQL injection vulnerability in Shopware e-commerce platform affecting versions prior to 5.4.3. Remote authenticated users can inject malicious SQL queries through unspecified input vectors, potentially allowing data exfiltration or database compromise.

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 Shopware installationLocate Shopware by checking for typical installation directories (like /shopware/, /shop/, or the root web directory) and look for the 'shopware.php' or 'index.php' entry point, or check the backend login page at /backend/Affected if Shopware is installed on the server
-
Determine installed Shopware versionAccess the Shopware admin backend and navigate to the configuration or settings section to view the version number, or check the 'shopware_version' value in the database or a version file in the installation directoryAffected if The installed version is lower than 5.4.3 (e.g., 5.4.0, 5.3.x, 5.2.x, etc.)
-
Verify admin interface accessibilityCheck if the Shopware backend (/backend/) is accessible from the network and confirm valid admin credentials exist in the systemAffected if The admin interface is accessible with valid user accounts, which is required for the authenticated SQL injection to be exploitable
-
Review database query logsEnable and review MySQL/MariaDB query logging or use a database monitoring tool to inspect incoming SQL queries for suspicious patterns, unexpected UNION statements, or tamper attemptsAffected if Suspicious SQL queries containing UNION, DROP, DELETE, or stacked queries appear in logs originating from Shopware application users
The environment is affected if Shopware is installed with a version prior to 5.4.3 and the admin backend is accessible to authenticated users, making SQL injection possible through the vulnerable input vectors.

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 data5.4.3
Upgrade Shopware to version 5.4.3 or later to apply the security patch. If immediate upgrade is not feasible, identify and sanitize the vulnerable input vectors referenced in SW-21404.
