Prior to version 4.0.0, malicious users may try to get access to resources they are not allowed to see, by creating resources with integers as names. One example where this is a risk, is when users define which users are allowed to run algorithms on their node. This may be defined by username or user id. Now, for example, if user id 13 is allowed to run tasks, and an attacker creates a username with username '13', they would be wrongly allowed to run an algorithm. There may also be other places in the code where such a mixup of resource ID or name leads to issues. Version 4.0.0 contains a patch for this issue. The best solution is to check when resources are created or modified, that the resource name always starts with a character."}, {"lang": "es", "value": "vantage6 es una infraestructura de aprendizaje federada que preserva la privacidad. Antes de la versi\u00f3n 4.0.0, los usuarios malintencionados pod\u00edan intentar obtener acceso a recursos que no pod\u00edan ver, creando recursos con n\u00fameros enteros como nombres. Un ejemplo en el que esto supone un riesgo es cuando los usuarios definen qu\u00e9 usuarios pueden ejecutar algoritmos en su nodo. Esto puede definirse por nombre de usuario o identificaci\u00f3n de usuario. Ahora, por ejemplo, si el ID de usuario 13 puede ejecutar tareas y un atacante crea un nombre de usuario con el nombre de usuario '13', se le permitir\u00eda ejecutar un algoritmo por error. Tambi\u00e9n puede haber otros lugares en el c\u00f3digo donde dicha combinaci\u00f3n de ID o nombre de recurso genera problemas. La versi\u00f3n 4.0.0 contiene un parche para este problema. La mejor soluci\u00f3n es comprobar, cuando se crean o modifican recursos, que el nombre del recurso siempre comience con un car\u00e1cter."}], "lastModified": "2023-10-17T16:06:32.323", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:vantage6:vantage6:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "21C07998-FF3A-4F49-B6B7-97E89CB0A6B4", "versionEndExcluding": "4.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
