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 · unedited
Magento versions 2.3.4 and earlier, 2.2.11 and earlier (see note), 1.14.4.4 and earlier, and 1.9.4.4 and earlier have a command injection vulnerability. Successful exploitation could lead to arbitrary code execution.

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 confidence

A command injection vulnerability exists in Magento e-commerce platform versions 2.3.4 and earlier, 2.2.11 and earlier, 1.14.4.4 and earlier, and 1.9.4.4 and earlier. Attackers can inject malicious system commands through unsanitized input, potentially achieving arbitrary code execution on the server.

MitigationUpgrade Magento to the latest patched version to remediate this vulnerability. Organizations running affected versions should prioritize patching given the critical CVSS score and potential for complete system 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 checks

Work through these to decide whether this CVE applies to you.

  1. Determine installed Magento version
    Log into the Magento Admin panel and navigate to System > Tools > Web Setup Wizard > System Upgrade, or check the composer.json file in the Magento root directory for the 'version' field
    Affected if The version is <= 1.9.4.4, <= 1.14.4.4, between 2.2.0 and 2.2.11 inclusive, or between 2.3.0 and 2.3.4 inclusive
  2. Identify Magento edition and branch
    Check the composer.json or app/etc/env.php for the edition type (Community or Enterprise) and confirm whether it is a 1.x or 2.x installation
    Affected if Running Magento 1.x versions 1.9.4.4 and below or 1.14.4.4 and below, or Magento 2.x versions 2.2.11 and below or 2.3.4 and below
  3. Locate the vulnerable input point
    Review the application code for unsanitized input handlers, specifically looking for user-controllable parameters passed to system command execution functions such as shell_exec, exec, passthru, or similar PHP functions
    Affected if The application accepts user input that flows directly into system command execution without sanitization

You are affected if your installed Magento version falls within the affected ranges AND the vulnerable input mechanism is accessible to attackers.

dbcve · scoped
Upgrade available Upgrade to a release after 2.3.4
Interim mitigation

Upgrade Magento to the latest patched version to remediate this vulnerability. Organizations running affected versions should prioritize patching given the critical CVSS score and potential for complete system compromise.

Recommended fix High confidence

Magento 2.2.12+ or 2.3.5+ (depending on your edition); Magento 1.x users should contact Adobe for Extended Support

  1. 1. Identify your current Magento installation version and edition (1.x or 2.x)
  2. 2. For Magento 1.x users: Contact Adobe for Extended Support options or plan migration to Magento 2.x, as Magento 1.x reached end-of-life in June 2020
  3. 3. For Magento 2.2.x users: Upgrade to version 2.2.12 or later
  4. 4. For Magento 2.3.x users: Upgrade to version 2.3.5 or later
  5. 5. Before upgrading in production, test the upgrade in a staging environment
  6. 6. Take a complete backup of the database and filesystem before applying the upgrade
  7. 7. After upgrade, verify the patch was applied by checking the installed version
Caveat Magento 1.x is end-of-life; Magento 2.x upgrades may require compatibility testing with custom extensions and themes
