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 •

A flaw was found in Ceph, relating to the URL processing on RGW backends. An attacker can exploit the URL processing by providing a null URL to crash the RGW, causing a denial of service. • https://bugzilla.redhat.com/show_bug.cgi?id=2139925 • CWE-177: Improper Handling of URL Encoding (Hex Encoding) •

An uncontrolled resource consumption vulnerability was discovered in HAProxy which could crash the service. This issue could allow an authenticated remote attacker to run a specially crafted malicious server in an OpenShift cluster. The biggest impact is to availability. • https://access.redhat.com/security/cve/CVE-2023-0056 https://bugzilla.redhat.com/show_bug.cgi?id=2160808 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 9.1EPSS: 0%CPEs: 6EXPL: 0CVE-2022-0670 – ceph: user/tenant can obtain access (read/write) to any share
https://notcve.org/view.php?id=CVE-2022-0670
A flaw was found in Openstack manilla owning a Ceph File system "share", which enables the owner to read/write any manilla share or entire file system. The vulnerability is due to a bug in the "volumes" plugin in Ceph Manager. This allows an attacker to compromise Confidentiality and Integrity of a file system. Fixed in RHCS 5.2 and Ceph 17.2.2. Se ha encontrado un fallo en Openstack manilla que posee un "share" del sistema de archivos Ceph, que permite al propietario leer/escribir cualquier manilla compartido o todo el sistema de archivos. • https://ceph.io/en/news/blog/2022/v17-2-2-quincy-released https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5O3XMDFZWA2FWU6GAYOVSFJPOUTXN42N https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TIRTTRG5O4YP2TNGDCDOHIHP2DM3DFBT https://access.redhat.com/security/cve/CVE-2022-0670 https://bugzilla.redhat.com/show_bug.cgi?id=2050728 • CWE-863: Incorrect Authorization •

https://notcve.org/view.php?id=CVE-2021-3979
A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks. Se ha encontrado un fallo de longitud de clave en Red Hat Ceph Storage. Un atacante puede explotar el hecho de que la longitud de la clave se pasa incorrectamente en un algoritmo de cifrado para crear una clave no aleatoria, que es más débil y puede ser explotada para la pérdida de confidencialidad e integridad en los discos cifrados. • https://access.redhat.com/security/cve/CVE-2021-3979 https://bugzilla.redhat.com/show_bug.cgi?id=2024788 https://github.com/ceph/ceph/commit/47c33179f9a15ae95cc1579a421be89378602656 https://github.com/ceph/ceph/pull/44765 https://lists.debian.org/debian-lts-announce/2023/10/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BPOK44BESMIFW6BIOGCN452AKKOIIT6Q https://tracker.ceph.com/issues/54006 • CWE-287: Improper Authentication CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
