CVE-2026-54205: TeamDavid: Server-Side Request Forgery (SSRF) via 'pathname' parameter in link storing functionality
Tobit Laboratories AG TeamDavid's Webbox 's link storing functionality (//ServerClientcelink.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.

If outbound connections to port 445 (SMB) are permitted, exploitation via the 'pathname' parameter can trigger the server to authenticate to attacker-controlled UNC paths (e.g., \\Server\Share). Block outbound SMB (TCP 445) to prevent outbound authentication attempts to arbitrary SMB endpoints.
