How to Fix CVE-2020-5679

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
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-2020-5679, 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 the patched release), 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-1021: Improper Restriction of Rendered UI Layers or Frames, where the web application does not restrict or incorrectly restricts frame objects or ui layers that belong to another application or domain. 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

Improper restriction of rendered UI layers or frames in EC-CUBE versions from 3.0.0 to 3.0.18 leads to clickjacking attacks. If a user accesses a specially crafted page while logged into the administrative page, unintended operations may be conducted.
