SchoolCMS 2.3.1 Theme Upload admin.php Upload() privilege escalation

A vulnerability, which was classified as critical, has been found in SchoolCMS 2.3.1 (Content Management System). Affected by this issue is the function Upload() of the file admin.php?m=admin&c=theme&a=upload of the component Theme Upload Handler. The manipulation with an unknown input leads to a privilege escalation vulnerability (PHP Code Execution). Using CWE to declare the problem leads to CWE-94. Impacted is confidentiality, integrity, and availability. CVE summarizes:

SchoolCMS version 2.3.1 allows file upload via the theme upload feature at admin.php?m=admin&c=theme&a=upload by using the .zip extension along with the _Static substring, changing the Content-Type to application/zip, and placing PHP code after the ZIP header. This ultimately allows execution of arbitrary PHP code in Public\Home\1_Static.php because of mishandling in the Application\Admin\Controller\ThemeController.class.php Upload() function.

The weakness was released 03/05/2019. This vulnerability is handled as CVE-2019-9572 since 03/05/2019. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 03/06/2019).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
