How to Fix CVE-2024-21518

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

opencart/opencart fixed: Latest secure release 
Upgrade opencart/opencart 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 opencart/opencart

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-21518, inspect your project dependencies for Opencart/opencart:

inspect dependencies for opencart/opencart

Analyze the terminal output to locate any version of Opencart/opencart 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-29: Path Traversal: '\..\filename', where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '\..\filename' (leading backslash dot dot) sequences that can resolve to a location that is outside of that directory. In Opencart/opencart, 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

This affects versions of the package opencart/opencart from 4.0.0.0. A Zip Slip issue was identified via the marketplace installer due to improper sanitization of the target path, allowing files within a malicious archive to traverse the filesystem and be extracted to arbitrary locations. An attacker can create arbitrary files in the web root of the application and overwrite other existing files by exploiting this vulnerability.
