Des chercheurs de la soci\u00e9t\u00e9 Horizon3 ont constat\u00e9 des probl\u00e8mes de s\u00e9curit\u00e9 dans la plupart des installations de la plateforme d'analyse et de visualisation de donn\u00e9es Apache Superset. Sur 2124 des 3176 serveurs publics d'Apache Superset \u00e9tudi\u00e9s, l'utilisation d'une cl\u00e9 de chiffrement par d\u00e9faut fournie dans l'exemple de fichier de configuration a \u00e9t\u00e9 identifi\u00e9e. Cette cl\u00e9 est utilis\u00e9e dans la biblioth\u00e8que Python Flask pour g\u00e9n\u00e9rer des cookies de session, permettant \u00e0 un attaquant connaissant la cl\u00e9 de cr\u00e9er de faux param\u00e8tres de session, se connecter \u00e0 l'interface web d'Apache Superset et t\u00e9l\u00e9charger des donn\u00e9es \u00e0 partir des bases de donn\u00e9es connect\u00e9es ou d'ex\u00e9cuter du code avec les droits d'Apache Superset. <\/p>\n

Il est int\u00e9ressant de noter que les chercheurs ont inform\u00e9 les d\u00e9veloppeurs du probl\u00e8me d\u00e8s 2021. Par la suite, dans la version Apache Superset 1.4.1, publi\u00e9e en janvier 2022, la valeur du param\u00e8tre SECRET_KEY a \u00e9t\u00e9 remplac\u00e9e par la cha\u00eene \u00ab CHANGE_ME_TO_A_COMPLEX_RANDOM_SECRET \u00bb, et une v\u00e9rification a \u00e9t\u00e9 ajout\u00e9e au code, qui g\u00e9n\u00e8re un avertissement dans les journaux lorsqu'une telle valeur est pr\u00e9sente. <\/p>\n

En f\u00e9vrier de cette ann\u00e9e, les chercheurs ont d\u00e9cid\u00e9 de refaire le scan des syst\u00e8mes vuln\u00e9rables et ont \u00e9t\u00e9 confront\u00e9s \u00e0 un manque d'attention aux avertissements, avec 67%. serveurs<\/a> Apache Superset continue d'utiliser des cl\u00e9s issues des exemples de configuration, mod\u00e8les de d\u00e9ploiement ou documentations. Parmi les organisations utilisant des cl\u00e9s par d\u00e9faut se trouvaient certaines grandes entreprises, universit\u00e9s et institutions publiques.

\"67<\/center> <\/p>\n

L'utilisation d'une cl\u00e9 fonctionnelle dans l'exemple de configuration est d\u00e9sormais consid\u00e9r\u00e9e comme une vuln\u00e9rabilit\u00e9 (CVE-2023-27524), qui a \u00e9t\u00e9 corrig\u00e9e dans la version Apache Superset 2.1 en g\u00e9n\u00e9rant une erreur bloquant le lancement de la plateforme lors de l'utilisation de la cl\u00e9 fournie dans l'exemple (seule la cl\u00e9 indiqu\u00e9e dans l'exemple de la version actuelle est prise en compte, les anciennes cl\u00e9s types et les cl\u00e9s des mod\u00e8les et documentations ne sont pas bloqu\u00e9es). Un script sp\u00e9cial a \u00e9t\u00e9 propos\u00e9 pour v\u00e9rifier la pr\u00e9sence de la vuln\u00e9rabilit\u00e9 \u00e0 distance.
