What is CVE-2019-16409?

CVE-2019-16409 is a medium-severity vulnerability in Silverstripe Silverstripe, published on 26 Sep 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

In the Versioned Files module through 2.0.3 for SilverStripe 3.x, unpublished versions of files are publicly exposed to anyone who can guess their URL.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.)
