Official description

Tobit Laboratories AG TeamDavid's Webbox does not enforce authentication or authorization checks when serving these log files. As a result, attackers can obtain sensitive error information or internal application details, potentially aiding in further attacks. 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.
