Description
Tobit Laboratories AG TeamDavid&#39;s Webbox &#39;s sending email, fax, SMS, etc. functionality accepts a <br />
@@INCLUDE command, which can be set to network locations using UNC paths<br />
(e.g., “\\Server\Share”). The server processes these paths without <br />
validation, resulting in outbound connection attempts to <br />
attacker-controlled SMB servers. This enables authenticated attackers to<br />
trigger the server to authenticate to arbitrary SMB endpoints, <br />
potentially exposing NTLM authentication information (such as NTLM <br />
hashes). If outbound connections to port 445 (SMB) are permitted, <br />
attackers can use this to conduct SMB relay or credential theft attacks.<br />
Exploitation of the “pathname” parameter is possible without <br />
authentication. This issue affects TeamDavid before Rollout 528.<br />
<br />
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.
