      "value": "Tobit Laboratories AG TeamDavid's Webbox 's link storing functionality (//ServerClient_celink.htm)\n accepts a “pathname” parameter, which can be set to network locations \nusing UNC paths (e.g., “\\\\Server\\Share”). The server processes these \npaths without validation, resulting in outbound connection attempts to \nattacker-controlled SMB servers. This enables authenticated attackers to\n trigger the server to authenticate to arbitrary SMB endpoints, \npotentially exposing NTLM authentication information (such as NTLM \nhashes). If outbound connections to port 445 (SMB) are permitted, \nattackers can use this to conduct SMB relay or credential theft attacks.\n Exploitation of the “pathname” parameter is possible without \nauthentication. This issue affects TeamDavid before Rollout 528.\n\nStarting 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 almacenamiento de enlaces de Webbox de TeamDavid de Tobit Laboratories AG (//ServerClient_celink.htm) acepta un parámetro ’pathname’, 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 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 ’pathname’ es posible sin autenticación. Este problema afecta a TeamDavid hasta el Rollout 524."
