When tasks produce output the service writes response data into files under /opt/PrinterInstallerClient/tmp/responses/ reusing the requested filename. The service follows symbolic links in the responses directory and writes as the service user (typically root), allowing a local, unprivileged user to cause the service to overwrite or create arbitrary files on the filesystem as root. This can be used to modify configuration files, replace or inject binaries or drivers, and otherwise achieve local privilege escalation and full system compromise.\u00a0This vulnerability has been identified by the vendor as: V-2023-019 \u2014 Arbitrary File Write as Root."}, {"lang": "es", "value": "Las versiones de Vasion Print (anteriormente PrinterLogic) Virtual Appliance Host anteriores a la 22.0.843 y de la Aplicaci\u00f3n anteriores a la 20.0.1923 (despliegues de cliente macOS/Linux) contienen una vulnerabilidad de escritura arbitraria de archivos a trav\u00e9s del manejo de archivos de respuesta. Cuando las tareas producen una salida, el servicio escribe datos de respuesta en archivos bajo /opt/PrinterInstallerClient/tmp/responses/ reutilizando el nombre de archivo solicitado. El servicio sigue enlaces simb\u00f3licos en el directorio de respuestas y escribe como el usuario del servicio (t\u00edpicamente root), permitiendo a un usuario local, sin privilegios, causar que el servicio sobrescriba o cree archivos arbitrarios en el sistema de archivos como root. Esto puede usarse para modificar archivos de configuraci\u00f3n, reemplazar o inyectar binarios o controladores, y de otro modo lograr la escalada de privilegios local y el compromiso total del sistema.
