CVSS: 7.5EPSS: 83%CPEs: 444EXPL: 7CVE-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 •
CVSS: 7.1EPSS: 0%CPEs: 8EXPL: 0CVE-2023-5366 – Openvswitch don't match packets on nd_target field
https://notcve.org/view.php?id=CVE-2023-5366
A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses. Se encontró una falla en Open vSwitch que permite que los paquetes de anuncios de vecinos ICMPv6 entre máquinas virtuales omitan las reglas de OpenFlow. Este problema puede permitir que un atacante local cree paquetes especialmente manipulados con un campo de dirección IP de destino modificado o falsificado que puede redirigir el tráfico ICMPv6 a direcciones IP arbitrarias. • http://www.openwall.com/lists/oss-security/2024/02/08/4 https://access.redhat.com/security/cve/CVE-2023-5366 https://bugzilla.redhat.com/show_bug.cgi?id=2006347 https://lists.debian.org/debian-lts-announce/2024/02/msg00004.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LFZADABUDOFI2KZIRQBYFZCIKH55RGY3 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/VYYUBF6OW2JG7VOFEOROHXGSJCTES3QO • CWE-345: Insufficient Verification of Data Authenticity •

https://notcve.org/view.php?id=CVE-2022-3248
A flaw was found in OpenShift API, as admission checks do not enforce "custom-host" permissions. This issue could allow an attacker to violate the boundaries, as permissions will not be applied. Se encontró una falla en la API de OpenShift, ya que las comprobaciones de admisión no aplican permisos de "custom-host". Este problema podría permitir que un atacante viole los límites, ya que no se aplicarán los permisos. • https://access.redhat.com/security/cve/CVE-2022-3248 https://bugzilla.redhat.com/show_bug.cgi?id=2072188 • CWE-863: Incorrect Authorization •
