CVE-2026-54207 Details
Description
Tobit Laboratories AG TeamDavid's Webbox 's move archive functionality (“!ArcEntryMove”) accepts an arbitrary path, 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 au-thenticated 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.
A vulnerability in Tobit Laboratories AG TeamDavid's Webbox application allows authenticated attackers to exploit the move archive functionality by sending UNC paths. The server processes these paths without validation, leading to unauthorized authentication attempts to SMB servers controlled by the attacker. This could expose NTLM authentication data, such as NTLM hashes. If the server is allowed to make outbound connections to port 445, this vulnerability could be used for SMB relay attacks or to steal credentials. Notably, the exploitation of the 'pathname' parameter can be done without authentication. This issue affects TeamDavid through Rollout 524.
Users are advised to update to the latest version of TeamDavid, as the current version may contain unresolved vulnerabilities. Additionally, organizations should restrict outbound SMB connections on port 445 and consider placing the TeamDavid web server behind a VPN or reverse proxy that filters requests.
