WebsiteBaker CMS < 2.13.10 File Upload RCE via Module Installation

Title source: cna
STIX 2.1

Description

WebsiteBaker CMS before 2.13.10 contains an unrestricted file upload vulnerability in the module installation feature that allows authenticated administrators to achieve remote code execution by uploading a crafted ZIP archive containing a PHP webshell alongside a valid info.php metadata file. Attackers can place the malicious archive through the module installation interface, causing the application to extract the webshell into a web-accessible modules/ subdirectory where it becomes immediately executable by any unauthenticated user via direct HTTP request.
