Official description
Tobit Laboratories AG TeamDavid's Webbox contains an open redirect vulnerability via the “replyUrl” parameter. An attacker can exploit this vulnerability to craft a URL within the application that, when visited, redirects the user’s browser to an arbitrary third-party site. This can be abused for phishing attacks, where users receive a trusted domain link but are redirected to a phishing website. 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.
