In MinIO before version RELEASE.2021-01-30T00-20-58Z there is a server-side request forgery vulnerability. The target application may have functionality for importing data from a URL, publishing data to a URL, or otherwise reading data from a URL that can be tampered with. The attacker modifies the calls to this functionality by supplying a completely different URL or by manipulating how URLs are built (path traversal etc.). In a Server-Side Request Forgery (SSRF) attack, the attacker can abuse functionality on the server to read or update internal resources. The attacker can supply or modify a URL which the code running on the server will read or submit data, and by carefully selecting the URLs, the attacker may be able to read server configuration such as AWS metadata, connect to internal services like HTTP enabled databases, or perform post requests towards internal services which are not intended to be exposed. This is fixed in version RELEASE.2021-01-30T00-20-58Z, all users are advised to upgrade. As a workaround you can disable the browser front-end with \"MINIO_BROWSER=off\" environment variable."}, {"lang": "es", "value": "MinIO es un Almacenamiento de Objetos de Alto Rendimiento publicado bajo la licencia Apache versi\u00f3n v2.0. En MinIO anterior a la versi\u00f3n RELEASE.2021-01-30T00-20-58Z, se presenta una vulnerabilidad de tipo server-side request forgery. La aplicaci\u00f3n objetivo puede tener una funcionalidad para importar datos de una URL, publicar datos en una URL o leer datos de una URL con que puedan ser alterada.
