CVE-2026-54205 | BDVDB-2026-356328 Detail

Description#

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 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.
