"value": "Nextcloud Text is an open source plaintext editing application which ships with the nextcloud server. In affected versions the Nextcloud Text application returned different error messages depending on whether a folder existed in a public link share. This is problematic in case the public link share has been created with \"Upload Only\" privileges. (aka \"File Drop\"). A link share recipient is not expected to see which folders or files exist in a \"File Drop\" share. Using this vulnerability an attacker is able to enumerate folders in such a share. Exploitation requires that the attacker has access to a valid affected \"File Drop\" link share. It is recommended that the Nextcloud Server is upgraded to 20.0.12, 21.0.4 or 22.0.1. Users who are unable to upgrade are advised to disable the Nextcloud Text application in the app settings."

"value": "Nextcloud Text es una aplicaci\u00f3n de edici\u00f3n de texto plano de c\u00f3digo abierto que se suministra con el servidor nextcloud. En las versiones afectadas la aplicaci\u00f3n Nextcloud Text devolv\u00eda diferentes mensajes de error dependiendo de si una carpeta exist\u00eda en un enlace p\u00fablico compartido. Esto es problem\u00e1tico en el caso de que el recurso compartido de enlace p\u00fablico haya sido creado con privilegios \"Upload Only\". (tambi\u00e9n se conoce como \"File Drop\"). No se espera que un destinatario de un enlace compartido vea qu\u00e9 carpetas o archivos existen en un recurso compartido \"File Drop\". Usando esta vulnerabilidad un atacante es capaz de enumerar las carpetas en dicho recurso compartido. La explotaci\u00f3n requiere que el atacante tenga acceso a un recurso compartido de enlace \"File Drop\" v\u00e1lido y afectado. Se recomienda actualizar el servidor Nextcloud a la versi\u00f3n 20.0.12, 21.0.4 o 22.0.1. Los usuarios que no puedan actualizar se les aconseja deshabilitar la aplicaci\u00f3n Nextcloud Text en la configuraci\u00f3n de la aplicaci\u00f3n"
