CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
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. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •
CVE-2019-10079
https://notcve.org/view.php?id=CVE-2019-10079
Apache Traffic Server is vulnerable to HTTP/2 setting flood attacks. Earlier versions of Apache Traffic Server didn't limit the number of setting frames sent from the client using the HTTP/2 protocol. Users should upgrade to Apache Traffic Server 7.1.7, 8.0.4, or later versions. Apache Traffic Server es vulnerable a los ataques de inundación de la configuración HTTP/2. Las versiones anteriores de Apache Traffic Server no limitaban el número de tramas de configuración enviadas desde el cliente utilizando el protocolo HTTP/2. • https://lists.apache.org/thread.html/392108390cef48af647a2e47b7fd5380e050e35ae8d1aa2030254c04%40%3Cusers.trafficserver.apache.org%3E https://lists.apache.org/thread.html/ad3d01e767199c1aed8033bb6b3f5bf98c011c7c536f07a5d34b3c19%40%3Cannounce.trafficserver.apache.org%3E https://lists.apache.org/thread.html/bde52309316ae798186d783a5e29f4ad1527f61c9219a289d0eee0a7%40%3Cdev.trafficserver.apache.org%3E • CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2019-9518 – Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9518
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://seclists.org/fulldisclosure/2019/Aug/16 https://access.redhat.com/errata/RHSA-2019:2925 https://access.redhat.com/errata/RHSA-2019:2939 https://access.redhat.com/errata/RHSA-2019:2955 https://access.redhat.com/errata/RHSA-2019:3892 https://access.redhat.com/errata/RHSA-2019:4352 https://access.redhat.com/errata/RHSA-2020:0727 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVE-2019-9516 – Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9516
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.

CVE-2019-9513 – Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service
https://notcve.org/view.php?id=CVE-2019-9513
Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU. Algunas implementaciones de HTTP / 2 son vulnerables a los bucles de recursos, lo que puede conducir a una denegación de servicio. El atacante crea múltiples flujos de solicitud y baraja continuamente la prioridad de los flujos de una manera que provoca un cambio considerable en el árbol de prioridad. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00014.html https://access.redhat.com/errata/RHSA-2019:2692 https:/ • CWE-400: Uncontrolled Resource Consumption •
