WebsiteBaker Org e.V. WebsiteBaker CMS vulnerabilities

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.

WebsiteBaker CMS before 2.13.10 contains a code injection vulnerability in the Droplets editor that allows authenticated administrators to inject arbitrary PHP code by submitting malicious content through the droplet Code field, which is written verbatim to a publicly accessible PHP file with no content sanitization. Attackers can save a PHP webshell via the save_droplet handler to a predictable path inside the modules directory, enabling unauthenticated users to achieve remote code execution by making direct HTTP requests to the written file.
