CVE-2026-54208

Tobit Laboratories AG TeamDavid's Webbox application is vulnerable to arbitrary file write, allowing an unauthenticated attacker to create or write into existing files on the server with attacker-controlled content. This is possible because user input is written directly to files without proper validation or restriction on file types. As a result, an attacker can create files (e.g., .htm), containing malicious JavaScript code. When a user accesses a file created in this way, stored cross-site scripting is triggered. This issue affects TeamDavid before Rollout 528. Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.

CVSS

Summary		(es) La aplicación Webbox de TeamDavid de Tobit Laboratories AG es vulnerable a la escritura arbitraria de archivos, lo que permite a un atacante no autenticado crear o escribir en archivos existentes en el servidor con contenido controlado por el atacante. Esto es posible porque la entrada del usuario se escribe directamente en los archivos sin una validación adecuada o restricción en los tipos de archivo. Como resultado, un atacante puede crear archivos (p. ej., .htm) que contengan código JavaScript malicioso. Cuando un usuario accede a un archivo creado de esta manera, se activa un cross-site scripting almacenado. Este problema afecta a TeamDavid hasta el Rollout 524.
