CVE-2024-42363

Prior to 3385, the user-controlled role parameter enters the application in the Kubernetes::RoleVerificationsController. The role parameter flows into the RoleConfigFile initializer and then into the Kubernetes::Util.parse_file method where it is unsafely deserialized using the YAML.load_stream method. This issue may lead to Remote Code Execution (RCE). This vulnerability is fixed in 3385.

Summary		(es) Antes de 3385, el parámetro de rol controlado por el usuario ingresa a la aplicación en Kubernetes::RoleVerificationsController. El parámetro de rol fluye hacia el inicializador RoleConfigFile y luego hacia el método Kubernetes::Util.parse_file donde se deserializa de forma insegura mediante el método YAML.load_stream. Este problema puede provocar la ejecución remota de código (RCE). Esta vulnerabilidad se soluciona en 3385.
