https://notcve.org/view.php?id=CVE-2023-45288
04 Apr 2024 — An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going... • https://github.com/hex0punk/cont-flood-poc • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.8EPSS: 36%CPEs: 8EXPL: 0CVE-2023-39325 – HTTP/2 rapid reset can cause excessive work in net/http
https://notcve.org/view.php?id=CVE-2023-39325
11 Oct 2023 — A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). N... • https://go.dev/cl/534215 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

10 Oct 2023 — The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. ... • https://github.com/imabee101/CVE-2023-44487 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2022-41723
28 Feb 2023 — A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of small requests. A flaw was found in golang. A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of requests. Philippe Antoine discovered that Go incorrectly handled crafted HTTP/2 streams. An attacker could possibly use this issue to cause a denial ... • https://go.dev/cl/468135 • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2022-41717
08 Dec 2022 — An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection. Un atacante puede provocar un crecimiento excesivo de la memoria en un servidor Go que acepta solicitudes HTTP/2. Las conexiones del servidor HTTP/2 contienen un caché de c... • https://github.com/domdom82/h2conn-exploit • CWE-770: Allocation of Resources Without Limits or Throttling •
