CVE-2023-48648
First published: Fri Nov 17 2023(Updated: )
Concrete CMS before 8.5.13 and 9.x before 9.2.2 allows unauthorized access because directories can be created with insecure permissions. File creation functions (such as the Mkdir() function) gives universal access (0777) to created folders by default. Excessive permissions can be granted when creating a directory with permissions greater than 0755 or when the permissions argument is not specified.
