CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2016-2140 – openstack-nova: Host data leak through resize/migration
https://notcve.org/view.php?id=CVE-2016-2140
The libvirt driver in OpenStack Compute (Nova) before 2015.1.4 (kilo) and 12.0.x before 12.0.3 (liberty), when using raw storage and use_cow_images is set to false, allows remote authenticated users to read arbitrary files via a crafted qcow2 header in an ephemeral or root disk. El controlador libvirt en OpenStack Compute (Nova) en versiones anteriores a 2015.1.4 (kilo) y 12.0.x en versiones anteriores a 12.0.3 (liberty), cuando usa almacenamiento en bruto y use_cow_images está establecido a false, permite a usuarios remotos autenticados leer archivos arbitrarios a través de una cabecera qcow2 manipulada en un disco efímero o root. An information-exposure flaw was found in the OpenStack Compute (nova) resize and migrate functionality. An authenticated user could write a malicious qcow header to an ephemeral or root disk, referencing a block device as a backing file. With a subsequent resize or migration, file system content on the specified device would be leaked to the user. • http://www.openwall.com/lists/oss-security/2016/03/08/6 http://www.securityfocus.com/bid/84277 https://bugs.launchpad.net/nova/+bug/1548450 https://security.openstack.org/ossa/OSSA-2016-007.html https://access.redhat.com/security/cve/CVE-2016-2140 https://bugzilla.redhat.com/show_bug.cgi?id=1313454 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The volume_utils._parse_volume_info function in OpenStack Compute (Nova) before 2015.1.3 (kilo) and 12.0.x before 12.0.1 (liberty) includes the connection_info dictionary in the StorageError message when using the Xen backend, which might allow attackers to obtain sensitive password information by reading log files or other unspecified vectors. La función volume_utils._parse_volume_info en OpenStack Compute (Nova) en versiones anteriores a 2015.1.3 (kilo) y 12.0.x en versiones anteriores a 12.0.1 (liberty) incluye el diccionario connection_info en el mensaje StorageError cuando utiliza el backend Xen, lo que permitiría a atacantes obtener información sensible de contraseña leyendo archivos de registro u otros vectores no especificados. • http://www.openwall.com/lists/oss-security/2016/01/07/8 http://www.openwall.com/lists/oss-security/2016/01/07/9 http://www.securityfocus.com/bid/80189 https://bugs.launchpad.net/nova/+bug/1516765 https://security.openstack.org/ossa/OSSA-2016-002.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2015-7548
OpenStack Compute (Nova) before 2015.1.3 (kilo) and 12.0.x before 12.0.1 (liberty), when using libvirt to spawn instances and use_cow_images is set to false, allow remote authenticated users to read arbitrary files by overwriting an instance disk with a crafted image and requesting a snapshot. OpenStack Compute (Nova) en versiones anteriores a 2015.1.3 (kilo) y 12.0.x en versiones anteriores a 12.0.1 (liberty), cuando se utiliza libvirt para producir instancias y use_cow_images se establece en false, permite a usuarios remotos autenticados leer archivos arbitrarios sobrescribiendo una instancia de disco con una imagen manipulada y solicitando una instantánea. A flaw was discovered in the OpenStack Compute (nova) snapshot feature when using the libvirt driver. A compute user could overwrite an attached instance disk with a malicious header specifying a backing file, and then request a snapshot, causing a file from the compute host to be leaked. This flaw only affects LVM or Ceph setups, or setups using filesystem storage with "use_cow_images = False". • http://rhn.redhat.com/errata/RHSA-2016-0018.html http://www.securityfocus.com/bid/80176 https://security.openstack.org/ossa/OSSA-2016-001.html https://access.redhat.com/security/cve/CVE-2015-7548 https://bugzilla.redhat.com/show_bug.cgi?id=1290511 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

OpenStack Compute (Nova) before 2014.1.4, 2014.2.x before 2014.2.3, and kilo before kilo-3 does not validate the origin of websocket requests, which allows remote attackers to hijack the authentication of users for access to consoles via a crafted webpage. OpenStack Compute (Nova) anterior a 2014.1.4, 2014.2.x anterior a 2014.2.3, y kilo anterior a kilo-3 no valida el origen de las solicitudes websocket, lo que permite a atacantes remotos secuestrar la autenticación de usuarios para el acceso a consolas a través de una página web manipulada. It was discovered that the OpenStack Compute (nova) console websocket did not correctly verify the origin header. An attacker could use this flaw to conduct a cross-site websocket hijack attack. Note that only Compute setups with VNC or SPICE enabled were affected by this flaw. • http://lists.openstack.org/pipermail/openstack-announce/2015-March/000341.html http://rhn.redhat.com/errata/RHSA-2015-0790.html http://rhn.redhat.com/errata/RHSA-2015-0843.html http://rhn.redhat.com/errata/RHSA-2015-0844.html https://bugs.launchpad.net/nova/+bug/1409142 https://access.redhat.com/security/cve/CVE-2015-0259 https://bugzilla.redhat.com/show_bug.cgi?id=1190112 • CWE-345: Insufficient Verification of Data Authenticity •

https://notcve.org/view.php?id=CVE-2014-3708
OpenStack Compute (Nova) before 2014.1.4 and 2014.2.x before 2014.2.1 allows remote authenticated users to cause a denial of service (CPU consumption) via an IP filter in a list active servers API request. OpenStack Compute (Nova) anterior a 2014.1.4 y 2014.2.x anterior a 2014.2.1 permite a usuarios remotos autenticados causar una denegación de servicio (consumo de CPU) a través de un filtro IP en una solicitud API para listar servidores activos. A denial of service flaw was found in the way OpenStack Compute (nova) looked up VM instances based on an IP address filter. An attacker with sufficient privileges on an OpenStack installation with a large amount of VMs could use this flaw to cause the main nova process to block for an extended amount of time. • http://lists.openstack.org/pipermail/openstack-announce/2014-October/000301.html http://rhn.redhat.com/errata/RHSA-2015-0843.html http://rhn.redhat.com/errata/RHSA-2015-0844.html http://www.securityfocus.com/bid/70777 https://bugs.launchpad.net/nova/+bug/1358583 https://access.redhat.com/security/cve/CVE-2014-3708 https://bugzilla.redhat.com/show_bug.cgi?id=1154951 • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
