CVSS: 7.5EPSS: 81%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: 7.6EPSS: 0%CPEs: 1EXPL: 0CVE-2022-39388 – Istio may allow identity impersonation if user has localhost access
https://notcve.org/view.php?id=CVE-2022-39388
Istio is an open platform to connect, manage, and secure microservices. In versions on the 1.15.x branch prior to 1.15.3, a user can impersonate any workload identity within the service mesh if they have localhost access to the Istiod control plane. Version 1.15.3 contains a patch for this issue. There are no known workarounds. Istio es una plataforma abierta para conectar, administrar y proteger microservicios. • https://github.com/istio/istio/commit/346260e5115e9fbc65ba8a559bc686e6ca046a32 https://github.com/istio/istio/commit/9a643e270421560afb2630e00f76d46a55499df9 https://github.com/istio/istio/security/advisories/GHSA-6c6p-h79f-g6p4 https://istio.io/latest/news/releases/1.15.x/announcing-1.15.3 • CWE-863: Incorrect Authorization •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-39278 – Istio vulnerable to denial of service attack due to Golang Regex Library
https://notcve.org/view.php?id=CVE-2022-39278
Istio is an open platform-independent service mesh that provides traffic management, policy enforcement, and telemetry collection. Prior to versions 1.15.2, 1.14.5, and 1.13.9, the Istio control plane, istiod, is vulnerable to a request processing error, allowing a malicious attacker that sends a specially crafted or oversized message which results in the control plane crashing when the Kubernetes validating or mutating webhook service is exposed publicly. This endpoint is served over TLS port 15017, but does not require any authentication from the attacker. For simple installations, Istiod is typically only reachable from within the cluster, limiting the blast radius. However, for some deployments, especially external istiod topologies, this port is exposed over the public internet. • https://github.com/istio/istio/security/advisories/GHSA-86vr-4wcv-mm9w https://istio.io/latest/news/releases/1.13.x/announcing-1.13.9 https://istio.io/latest/news/releases/1.15.x/announcing-1.15.2 https://istio.io/news/releases/1.14.x/announcing-1.14.5 https://access.redhat.com/security/cve/CVE-2022-39278 https://bugzilla.redhat.com/show_bug.cgi?id=2148199 • CWE-400: Uncontrolled Resource Consumption •
