  "details" : [ "In certain proxy configurations, a denial of service attack against Apache HTTP Server versions 2.4.26 through to 2.4.63 can be triggered by untrusted clients causing an assertion in mod_proxy_http2.\nConfigurations affected are a reverse proxy is configured for an HTTP/2 backend, with ProxyPreserveHost set to \"on\".", "An assertion failure flaw was found in Apache httpd. Untrusted clients can send inputs that trigger an assertion failure in the mod_proxy_http2 module, which likely results in an Apache HTTP server crash or denial of service (DoS)." ],
  "statement" : "The vulnerability only affects Appache httpd if a reverse proxy is configured for an HTTP/2 backend, with the ProxyPreserveHost set to \\\"on\\\".\nThis vulnerability is rated as Moderate because it requires a highly specific and non-default configuration to be exploitable—namely, an Apache HTTP Server acting as a reverse proxy with an HTTP/2 backend and ProxyPreserveHost set to \"on\". The flaw results in an assertion failure in the mod_proxy_http2 module when handling specially crafted inputs from untrusted clients. While this can lead to a denial of service via server crash, the impact is limited to availability, with no risk of remote code execution or data leakage. Additionally, the condition is recoverable through a simple restart, and there is no persistent state corruption.",
