Tobit Laboratories AG TeamDavid's Webbox 's sending email, fax, SMS, etc. functionality accepts a
@@INCLUDE command, which can be set to network locations using UNC paths
(e.g., “\\Server\Share”). The server processes these paths without
validation, resulting in outbound connection attempts to
attacker-controlled SMB servers. This enables authenticated attackers to
trigger the server to authenticate to arbitrary SMB endpoints,
potentially exposing NTLM authentication information (such as NTLM
hashes).
If outbound connections to port 445 (SMB) are permitted,
attackers can use this to conduct SMB relay or credential theft attacks. Exploitation of the “pathname” parameter is possible without
authentication. This issue affects TeamDavid through Rollout 524.
