Prior to 7.3.2, src/Kunstmaan/MediaBundle/Helper/File/FileHandler.php performs the blacklisted_extensions check case-sensitively in FileHandler::getFilePath and lowercases the stored extension afterward. An authenticated backend user with media access can upload a mixed-case executable extension such as PHP that bypasses the check and is stored in the web-accessible media directory with an executable lowercase extension. The default blacklist also omits several server-executable extension types, allowing the same code-execution impact where the web server executes uploaded files. This issue is fixed in version 7.3.2.</p> <p><strong>Affected:</strong> KunstmaanBundlesCMS, kunstmaan bundles-cms, kunstmaan media-bundle</p> <p>Kunstmaan CMS is an open source content management system based on the Symfony framework.
