      "value": "A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 6). The application does not properly sanitize user input in the /api/sftp/uploadFiles endpoint, allowing the injection of shell command payloads via crafted directory names. These payloads are stored and executed when directory listings are retrieved. This could allow an authenticated remote attacker to execute arbitrary commands on the underlying operating system with the privileges of the affected service user (sinecins)."

      "value": "Una vulnerabilidad ha sido identificada en SINEC INS (Todas las versiones anteriores a V1.0 SP2 Update 6). La aplicación no sanitiza correctamente la entrada del usuario en el endpoint /api/sftp/uploadFiles, permitiendo la inyección de cargas útiles de comandos de shell a través de nombres de directorio manipulados. Estas cargas útiles se almacenan y ejecutan cuando se recuperan los listados de directorios. Esto podría permitir a un atacante remoto autenticado ejecutar comandos arbitrarios en el sistema operativo subyacente con los privilegios del usuario de servicio afectado (sinecins)."
