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: 8.8EPSS: 0%CPEs: 4EXPL: 0CVE-2021-3495 – kiali/kiali-operator: can deploy specified image to any namespace
https://notcve.org/view.php?id=CVE-2021-3495
An incorrect access control flaw was found in the kiali-operator in versions before 1.33.0 and before 1.24.7. This flaw allows an attacker with a basic level of access to the cluster (to deploy a kiali operand) to use this vulnerability and deploy a given image to anywhere in the cluster, potentially gaining access to privileged service account tokens. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo de control de acceso incorrecto en kiali-operator en versiones anteriores a 1.33.0 y versiones anteriores a 1.24.7. este fallo permite a un atacante con un nivel básico de acceso al clúster (para implementar un operando kiali) usar esta vulnerabilidad e implementar una imagen determinada en cualquier lugar del clúster, potencialmente consiguiendo acceso a tokens de cuentas de servicio privilegiadas. La mayor amenaza de esta vulnerabilidad es la confidencialidad e integridad de los datos, así como la disponibilidad del sistema An incorrect access control flaw was found in the kiali-operator. • https://bugzilla.redhat.com/show_bug.cgi?id=1947361 https://kiali.io/news/security-bulletins/kiali-security-003 https://access.redhat.com/security/cve/CVE-2021-3495 • CWE-281: Improper Preservation of Permissions •

https://notcve.org/view.php?id=CVE-2019-25014
A NULL pointer dereference was found in pkg/proxy/envoy/v2/debug.go getResourceVersion in Istio pilot before 1.5.0-alpha.0. If a particular HTTP GET request is made to the pilot API endpoint, it is possible to cause the Go runtime to panic (resulting in a denial of service to the istio-pilot application). Se encontró una desreferencia del puntero NULL en el archivo pkg/proxy/envoy/v2/debug.go en la función getResourceVersion en Istio pilot versiones anteriores a 1.5.0-alpha.0. Si es realizado una petición HTTP GET en particular al endpoint de la API pilot, es posible que el tiempo de ejecución de Go entre en pánico (resultando en una denegación de servicio para la aplicación istio-pilot) An out-of-bounds read flaw was found in istio-pilot.
