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-2023-4853 – Quarkus: http security policy bypass
https://notcve.org/view.php?id=CVE-2023-4853
A flaw was found in Quarkus where HTTP security policies are not sanitizing certain character permutations correctly when accepting requests, resulting in incorrect evaluation of permissions. This issue could allow an attacker to bypass the security policy altogether, resulting in unauthorized endpoint access and possibly a denial of service. Se encontró una falla en Quarkus donde las políticas de seguridad HTTP no sanitiza correctamente ciertas permutaciones de caracteres al aceptar solicitudes, lo que resulta en una evaluación incorrecta de los permisos. Este problema podría permitir que un atacante eluda la política de seguridad por completo, lo que resultaría en un acceso no autorizado al endpoint y posiblemente una Denegación de Servicio. • https://access.redhat.com/errata/RHSA-2023:5170 https://access.redhat.com/errata/RHSA-2023:5310 https://access.redhat.com/errata/RHSA-2023:5337 https://access.redhat.com/errata/RHSA-2023:5446 https://access.redhat.com/errata/RHSA-2023:5479 https://access.redhat.com/errata/RHSA-2023:5480 https://access.redhat.com/errata/RHSA-2023:6107 https://access.redhat.com/errata/RHSA-2023:6112 https://access.redhat.com/errata/RHSA-2023:7653 https://access.redhat.com/security/cve • CWE-148: Improper Neutralization of Input Leaders CWE-863: Incorrect Authorization •
CVE-2023-2974 – Quarkus-core: tls protocol configured with quarkus.http.ssl.protocols is not enforced, client can enforce weaker supported tls protocol
https://notcve.org/view.php?id=CVE-2023-2974
A vulnerability was found in quarkus-core. This vulnerability occurs because the TLS protocol configured with quarkus.http.ssl.protocols is not enforced, and the client can force the selection of the weaker supported TLS protocol. • https://access.redhat.com/errata/RHSA-2023:3809 https://access.redhat.com/security/cve/CVE-2023-2974 https://bugzilla.redhat.com/show_bug.cgi?id=2211026 • CWE-757: Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade') •
