Concrete CMS allows unauthorized access because directories can be created with insecure permissions
Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Packagist | concrete5/concrete5 | < 8.5.13 | 8.5.13 |
| Packagist | concrete5/concrete5 | >= 9.0.0, < 9.2.2 | 9.2.2 |
Details
As written in the advisory (Markdown source, shown as plain text).
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.
