CVE-2023-44487

Rapid Reset Client Rapid Reset Client 是一款用于测试针对 CVE-2023-44487（快速重置 DDoS 攻击向量）的缓解措施和暴露程度的工具。它实现了一个最小的 HTTP/2 客户端，该客户端打开单个 TCP 套接字，协商 TLS，忽略证书，并交换 SETTINGS 帧。然后，客户端发送快速的 HEADERS 帧，随后发送 RSTSTREAM 帧。初始配置后，它监控（但不处理）来自服务器的帧，并将其输出到标准输出。 基于漏洞 CVE-2023-44487 的脚本修改 提供了为 Windows 编译的脚本 cve.bat，以及为在其他系统上通过...
