CVE-2019-7930
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 · uneditedA file upload restriction bypass exists in Magento 2.1 prior to 2.1.18, Magento 2.2 prior to 2.2.9, Magento 2.3 prior to 2.3.2. An authenticated user with administrator privileges to the import feature can make modifications to a configuration file, resulting in potentially unauthorized removal of file upload restrictions. This can result in arbitrary code execution when a malicious file is then uploaded and executed on the system.
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 confidenceA file upload restriction bypass in Magento 2.x allows authenticated administrators to modify a configuration file via the import feature, removing upload restrictions and enabling arbitrary code execution through malicious file uploads.

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 Magento 2 installed versionLocate the version file in your Magento installation (for example, check composer.json or the version.php file in app/etc/). Alternatively, log into the admin panel and look at the footer for the version number.Affected if The installed version is >= 2.1.0 and < 2.1.18, OR >= 2.2.0 and < 2.2.9, OR >= 2.3.0 and < 2.3.2
-
Verify administrator access to import feature existsLog into the Magento admin panel and navigate to System > Import (or System > Data Transfer > Import). Confirm whether the logged-in administrator role has permission to access and use the import functionality.Affected if An administrator account with import functionality access exists in the system
-
Review file upload configuration for unexpected modificationsInspect the system configuration files related to file uploads, such as the CSV import settings or upload path configurations under Stores > Configuration > Advanced > System. Look for any non-standard values that would allow uploading executable file types.Affected if File upload restrictions have been weakened or removed from their default secure settings
The environment is affected if the Magento 2 version falls within the vulnerable ranges AND administrators have access to the import feature.

From vendor data2.1.182.2.92.3.2
Apply the vendor patches by updating to Magento 2.1.18+, 2.2.9+, or 2.3.2+ respectively, and review administrator access to the import feature.
