CVE-2026-54205

Tobit Laboratories AG TeamDavid's Webbox 's link storing functionality (//ServerClient_celink.htm)
 accepts a “pathname” parameter, 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.
