Description
Tobit Laboratories AG TeamDavid's Webbox is vulnerable to HTTP header injection through the request body in the application's link storing functionality (//ServerClient_celink.htm), which is appended to the redirect target in the 302 HTTP response. If a line feed is added, this will also be added to the redirect link, resulting in the ability to control the response headers. 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.
