CVE-2026-54204

Full vulnerability record from the local CVENow database.

Description

Tobit Laboratories AG TeamDavid's Webbox 's search functionality accepts a “pathnameroot” 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 unauthenticated 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 “pathnameroot” 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.

      "value": "La funcionalidad de búsqueda de Webbox de TeamDavid de Tobit Laboratories AG acepta un parámetro ’pathnameroot’, que puede configurarse para ubicaciones de red utilizando rutas UNC (p. ej., ’\\\\Server\\Share’). El servidor procesa estas rutas sin validación, lo que resulta en intentos de conexión saliente a servidores SMB controlados por el atacante. Esto permite a los atacantes no autenticados activar que el servidor se autentique en puntos finales SMB arbitrarios, exponiendo potencialmente información de autenticación NTLM (como hashes NTLM). Si se permiten las conexiones salientes al puerto 445 (SMB), los atacantes pueden usar esto para realizar ataques de retransmisión SMB o robo de credenciales. La explotación del parámetro ’pathnameroot’ es posible sin autenticación.\n\nEste problema afecta a TeamDavid hasta el Rollout 524."
