## What is CVE-2019-9572?

CVE-2019-9572 is a high-severity vulnerability in n/a, published on 5 Mar 2019. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

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.
