    Le 10 octobre 2023, une vulnérabilité relative au protocole HTTP/2 permettant une attaque par déni de service a été découverte. Cette vulnérabilité a été classée avec un score CVSS 3.x de 7.5 (HIGH). (https://nvd.nist.gov/vuln/detail/CVE-2023-44487)

    Se pose alors la question de l'impact de cette vulnérabilité sur GoFAST. Initialement, nous utilisons le protocole HTTP/2 pour les services web de la plateforme. Cependant, nous ne sommes pas affectés par cette attaque, car les valeurs des paramètres "keepalive_requests" et "http2_max_concurrent_streams" sont celles par défaut dans la configuration de notre service web. Vous pouvez consulter l'article de nginx à ce sujet ici : https://www.nginx.com/blog/http-2-rapid-reset-attack-impacting-f5-nginx-products/

    Nous continuerons de surveiller cette vulnérabilité et, si nécessaire, nous ajouterons les paramètres "limit_conn" et "limit_req" lors de la prochaine version de GoFAST.
