CVSS: 7.8EPSS: 26%CPEs: 1EXPL: 1CVE-2024-28182 – Reading unbounded number of HTTP/2 CONTINUATION frames to cause excessive CPU usage
https://notcve.org/view.php?id=CVE-2024-28182
04 Apr 2024 — nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream. There is no workaround for this vulnerability. nghttp2 es una implementación del protocolo de... • https://github.com/lockness-Ko/CVE-2024-27316 • CWE-390: Detection of Error Condition Without Action CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2023-44487
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 •
CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2023-35945 – Envoy vulnerable to HTTP/2 memory leak in nghttp2 codec
https://notcve.org/view.php?id=CVE-2023-35945
13 Jul 2023 — Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy’s HTTP/2 codec may leak a header map and bookkeeping structures upon receiving `RST_STREAM` immediately followed by the `GOAWAY` frames from an upstream server. In nghttp2, cleanup of pending requests due to receipt of the `GOAWAY` frame skips de-allocation of the bookkeeping structure and pending compressed header. The error return [code path] is taken if connection is already marked for not sending more requests due to `GOAWAY` fram... • https://github.com/envoyproxy/envoy/security/advisories/GHSA-jfxv-29pc-x22r • CWE-400: Uncontrolled Resource Consumption CWE-459: Incomplete Cleanup •
CVSS: 7.5EPSS: 0%CPEs: 23EXPL: 0CVE-2020-11080 – Denial of service in nghttp2
https://notcve.org/view.php?id=CVE-2020-11080
03 Jun 2020 — In nghttp2 before version 1.41.0, the overly large HTTP/2 SETTINGS frame payload causes denial of service. The proof of concept attack involves a malicious client constructing a SETTINGS frame with a length of 14,400 bytes (2400 individual settings entries) over and over again. The attack causes the CPU to spike at 100%. nghttp2 v1.41.0 fixes this vulnerability. There is a workaround to this vulnerability. Implement nghttp2_on_frame_recv_callback callback, and if received frame is SETTINGS frame and the num... • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00024.html • CWE-400: Uncontrolled Resource Consumption CWE-707: Improper Neutralization CWE-770: Allocation of Resources Without Limits or Throttling •

08 May 2018 — nghttp2 version >= 1.10.0 and nghttp2 <= v1.31.0 contains an Improper Input Validation CWE-20 vulnerability in ALTSVC frame handling that can result in segmentation fault leading to denial of service. This attack appears to be exploitable via network client. This vulnerability appears to have been fixed in >= 1.31.1. nghttp2 hasta la versión 1.10.0 y nghttp2 en versiones 1.31.0 y anteriores contienen una vulnerabilidad de validación incorrecta de entradas (CWE-20) en la gestión de tramas ALTSVC que puede re... • http://www.securityfocus.com/bid/103952 • CWE-20: Improper Input Validation CWE-476: NULL Pointer Dereference •
