How to Fix CVE-2020-5590

To remediate this vulnerability, upgrade all affected Ec cube/ec cube dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

ec-cube/ec-cube fixed: Latest secure release 
Upgrade ec-cube/ec-cube to Latest secure release
ec-cube/ec-cube fixed: 4.0.4 
Upgrade ec-cube/ec-cube to 4.0.4
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 ec-cube/ec-cube

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-5590, inspect your project dependencies for Ec cube/ec cube:

inspect dependencies for ec-cube/ec-cube

Analyze the terminal output to locate any version of Ec cube/ec cube in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.4), 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-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Ec cube/ec cube, 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

Directory traversal vulnerability in EC-CUBE 3.0.0 to 3.0.18 and 4.0.0 to 4.0.3 allows remote authenticated attackers to delete arbitrary files and/or directories on the server via unspecified vectors.
