DescriptionNVD

In Pimcore before 5.7.1, an attacker with limited privileges can trigger execution of a .phar file via a phar:// URL in a filename parameter, because PHAR uploads are not blocked and are reachable within the phar://../../../../../../../../var/www/html/web/var/assets/ directory, a different vulnerability than CVE-2019-10867 and CVE-2019-16318.
