How to Fix CVE-2019-16409

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

symbiote/silverstripe-versionedfiles fixed: Latest secure release 
Upgrade symbiote/silverstripe-versionedfiles to Latest secure release
silverstripe/framework fixed: 4.3.5 
Upgrade silverstripe/framework to 4.3.5
silverstripe/framework fixed: 4.4.4 
Upgrade silverstripe/framework to 4.4.4
Verify Direct and Transitive Dependencies

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In Symbiote/silverstripe versionedfiles, 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

In the Versioned Files module through 2.0.3 for SilverStripe 3.x, unpublished versions of files are publicly exposed to anyone who can guess their URL. This guess could be highly informed by a basic understanding of the symbiote/silverstripe-versionedfiles source code. (Users who upgrade from SilverStripe 3.x to 4.x and had Versioned Files installed have no further need for this module, because the 4.x release has built-in versioning. However, nothing in the upgrade process automates the destruction of these insecure artefacts, nor alerts the user to the criticality of destruction.)
