CVE-2020-5776
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 · uneditedCurrently, all versions of MAGMI are vulnerable to CSRF due to the lack of CSRF tokens. RCE (via phpcli command) is possible in the event that a CSRF is leveraged against an existing admin session for MAGMI.
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 confidenceMAGMI (Magento Mass Importer) lacks CSRF tokens on all state-changing admin operations, allowing attackers to craft malicious requests that execute with the privileges of an authenticated admin session. The vulnerability specifically enables Remote Code Execution through abuse of the phpcli command functionality when combined with social engineering to target an active admin session.

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.
-
Locate MAGMI installation in the environmentSearch for magmi directory or files (e.g., magmi/web/magmi.php, magmi/conf/magmi.ini) in the web root or Magento directory structureAffected if MAGMI directory or files are found in the environment
-
Identify admin authentication mechanismCheck if MAGMI admin panel is accessible (typically at /magmi/web/magmi.php or similar admin path) and requires loginAffected if Admin panel is accessible without authentication or uses weak auth
-
Inspect admin forms for CSRF token presenceExamine the HTML source of MAGMI admin forms (especially configuration save, import execution, and plugin settings pages) and look for hidden CSRF token fields or anti-CSRF tokens in form markupAffected if Forms lack hidden CSRF token fields or tokens are not validated server-side
-
Check phpcli command functionality configurationLocate MAGMI plugin or configuration files that enable phpcli execution (search for phpcli, shell_exec, or command execution related settings in MAGMI conf directory)Affected if phpcli or shell command execution features are enabled in MAGMI configuration
-
Verify session management and token validationReview MAGMI source code (particularly request handlers in magmi/web/ and magmi/inc/ directories) to determine if $_POST or $_GET parameters are validated against a CSRF token before processing state-changing operationsAffected if State-changing admin operations (import, save config, plugin enable/disable) process requests without validating CSRF tokens
If MAGMI is installed and admin forms lack CSRF token validation while phpcli functionality is enabled, the environment is vulnerable to CVE-2020-5776.

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 dataImplement anti-CSRF tokens (synchronizer token pattern) on all admin actions, particularly those invoking shell commands. Additionally, consider restricting admin session access by IP and implementing shorter session timeouts to reduce the CSRF attack window.
