Validation Bypass

neutron is vulnerable to an IP address validation bypass. Non-privileged tenants are able to create and attach ports without specifying an IP address, which could lead to a denial of service condition when an assigned IP address conflict occurs with existing guests or routers...

Information Disclosure

openstack-neutron is vulnerable to information disclosure attacks. The vulnerability exists as a race-condition flaw was discovered in openstack-neutron before 7.2.0-12.1, 8.x before 8.3.0-11.1, 9.x before 9.3.1-2.1, and 10.x before 10.0.2-1.1, where, following a minor overcloud update, neutron...

Authorization Bypass

openstack-neutron is vulnerable to authorization bypass. Neutron functionality includes internal firewall management between networks. Due to the relaxed nature of particular rules, it is possible for machines on the same layer 2 networks to forge non-IP traffic, such as ARP and DHCP requests and...

Anti-Spoofing Controls Bypass

openstack-neutron is vulnerable to anti-spoofing controls bypass. Authenticated users using the ML2 plugin or the security groups AMQP API are able to set the deviceowner field to an arbitrary value starting with network: on networks they do not own. Setting the affected field before the security...

Denial Of Service (DoS)

openstack-neutron is vulnerable to denial of service DoS attacks. The vulnerability exists as OpenStack Neutron before 2014.2.4 juno and 2015.1.x before 2015.1.1 kilo, when using the IPTables firewall driver, allows remote authenticated users to cause a denial of service L2 agent crash by adding ...

Denial Of Service (DoS)

openstack-neutron is vulnerable to denial of service DoS attacks. The vulnerability exists as OpenStack Neutron before 2014.1.4 and 2014.2.x before 2014.2.1 allows remote authenticated users to cause a denial of service crash via a crafted dnsnameservers value in the DNS configuration...

Privilege Escalation

openstack-neutron is vulnerable to privilege escalation attacks. The vulnerability exists as it was discovered that unprivileged users could in some cases reset admin-only network attributes to their default values. This could lead to unexpected behavior or in some cases result in a denial of...

Privilege Escalation

openstack-neutron is vulnerable to privilege escalation attacks. The vulnerability exists as the default configuration in a sudoers file in the Red Hat openstack-neutron package before 2014.1.2-4, as used in Red Hat Enterprise Linux Open Stack Platform 5.0 for Red Hat Enterprise Linux 6, allows...

Privilege Escalation

openstack-neutron is vulnerable to privilege escalation attacks. The vulnerability exists as the default configuration in the Red Hat openstack-neutron package before 2013.2.3-7 does not properly set a configuration file for rootwrap, which allows remote attackers to gain privileges via a crafted...

Denial Of Service (DoS)

openstack-neutron is vulnerable to denial of service. There was no enforced quota on the amount of allowed address pairs, allowing a remote authenticated attacker to deplete system resources by creating a large number of allowed address pairs...

Information Disclosure

openstack-nova is vulnerable to information disclosure attacks. The vulnerability exists as an interaction error in OpenStack Nova and Neutron before Havana 2013.2.1 and icehouse-1 does not validate the instance ID of the tenant making a request, which allows remote tenants to obtain sensitive...

Bruteforce Attack

openstack-nova is vulnerable to bruteforce attacks. The vulnerability exists as api/metadata/handler.py in OpenStack Compute Nova before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2, when proxying metadata requests through Neutron, makes it easier for remote attackers to guess instanc...

Authorization Bypass

openstack-neutron is vulnerable to authorization bypass. An authenticated user is able to bypass security group restrictions with an invalid CIDR to add a security group rule which would cause the openvswitch-agent process to fail and prevent further rules from being applied...

Security Bulletin: IBM Cloud Manager with OpenStack is affected by a vulnerability found in OpenStack Neutron (CVE-2017-7543)

Summary A vFinder security vulnerability has been identified in OpenStack Neutron that is used by IBM Cloud Manager with OpenStack. IBM Cloud Manager with OpenStack has addressed the vulnerability. Vulnerability Details CVEID: CVE-2017-7543 DESCRIPTION: OpenStack neutron could allow a remote...

openstack-neutron: A router interface out of subnet IP range results in a denial of service

When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from...

Moderate: Red Hat Security Advisory: openstack-neutron security and bug fix update

An update for openstack-neutron is now available for Red Hat OpenStack Platform 10.0 Newton. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each...

Information Disclosure

neutron is vulnerable to information disclosure. The Agent OVS interface adds ports without a VLAN tag. This allows a port to become a trunk port and receive traffic from external networks or any other ports sending traffic on br-int, if the neutron-openvswitch-agent fails to set the VLAN tag...
