Xerte Online Toolkits versions 3.14 and earlier contain an unauthenticated arbitrary file upload vulnerability in the template import functionality that allows remote attackers to execute arbitrary code by uploading a crafted ZIP archive containing malicious PHP payloads. Attackers can bypass authentication checks in the import.php file to upload a template archive with PHP code in the media directory, which gets extracted to a web-accessible path where the malicious PHP can be directly accessed and executed under the web server context.

Xerte Online Toolkits versions 3.14 and earlier contain an unauthenticated arbitrary file upload vulnerability in the template import functionality. The issue exists in /website_code/php/import/import.php where missing authentication checks allow an attacker to upload a crafted ZIP archive disguised as a project template. The archive can contain a malicious PHP payload placed in the media/ directory, which is extracted into a web-accessible USER-FILES/{projectID}--{targetFolder}/ path. An attacker can then directly access the uploaded PHP file to achieve remote code execution under the web server context.
