magento/community-edition fixed: Latest secure release 
Upgrade magento/community-edition to Latest secure release
magento/community-edition fixed: 2.3.4-p2 
Upgrade magento/community-edition to 2.3.4-p2
magento/core fixed: 1.9.4.5 
Upgrade magento/core to 1.9.4.5
magento/project-community-edition fixed: Latest secure release 
Upgrade magento/project-community-edition to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for magento/community-edition

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-9578, inspect your project dependencies for Magento/community edition:

inspect dependencies for magento/community-edition

Analyze the terminal output to locate any version of Magento/community edition in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.4-p2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Magento/community edition, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
