What it is

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.
