Vulnerability Description
The Webbox of TeamDavid by Tobit Laboratories AG constructs redirect URLs using user-supplied input, which is appended to the redirect target in a 302 HTTP response. By using URL-encoded characters such as “%2e” (representing a dot), an attacker can manipulate the portion of the URL following the top-level domain (TLD). If a similar, registerable TLD exists (for example, if “.com” is the application’s domain, and “.company” is available for registration), an attacker can craft a URL to redirect users to a malicious “.company” domain. By using URL-encoded line feeds, it becomes possible to insert arbitrary response headers in the server's HTTP response. This issue affects TeamDavid through Rollout 524.
