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-2019-9515 – Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service

https://notcve.org/view.php?id=CVE-2019-9515

Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. Algunas implementaciones de HTTP / 2 son vulnerables a una inundación de configuraciones, lo que puede conducir a una denegación de servicio. • 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-2019:2766 https://access.redhat.com/errata/RHSA-2019:2796 https://access.redhat.com/errata/RHSA-2019:2861 https://access.redhat.com/errata/RHSA-2019:2925 https://access.redhat.com/errata/RHSA-2019:2939 https://access.redhat.com/errata/RHSA-2019:2955 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

CVE-2019-9514 – Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service

https://notcve.org/view.php?id=CVE-2019-9514

Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both. Algunas implementaciones de HTTP / 2 son vulnerables a una inundación de reinicio, lo que puede conducir a una denegación de servicio. El atacante abre una serie de secuencias y envía una solicitud no válida sobre cada secuencia que debería solicitar una secuencia de tramas RST_STREAM del par. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00076.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00021.html 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 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
