Openstack Security Vulnerabilities

CVE-2021-3656

A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malici...

CVE-2021-3930

An off-by-one error was found in the SCSI device emulation in QEMU. It could occur while processing MODE SELECT commands in mode_sense_page() if the 'page' argument was set to MODE_PAGE_ALLS (0x3f). A malicious guest could use this flaw to potentially crash QEMU, resulting in a denial of service co...

CVE-2021-4180

An information exposure flaw in openstack-tripleo-heat-templates allows an external user to discover the internal IP or hostname. An attacker could exploit this by checking the www_authenticate_uri parameter (which is visible to all end users) in configuration files. This would give sensitive infor...

CVE-2022-1655

An Incorrect Permission Assignment for Critical Resource flaw was found in Horizon on Red Hat OpenStack. Horizon session cookies are created without the HttpOnly flag despite HorizonSecureCookies being set to true in the environmental files, possibly leading to a loss of confidentiality and integri...

CVE-2022-3100

A flaw was found in the openstack-barbican component. This issue allows an access policy bypass via a query string when accessing the API.

CVE-2022-3101

A flaw was found in tripleo-ansible. Due to an insecure default configuration, the permissions of a sensitive file are not sufficiently restricted. This flaw allows a local attacker to use brute force to explore the relevant directory and discover the file, leading to information disclosure of impo...

CVE-2022-3146

A flaw was found in tripleo-ansible. Due to an insecure default configuration, the permissions of a sensitive file are not sufficiently restricted. This flaw allows a local attacker to use brute force to explore the relevant directory and discover the file. This issue leads to information disclosur...

CVE-2022-38065

A privilege escalation vulnerability exists in the oslo.privsep functionality of OpenStack git master 05194e7618 and prior. Overly permissive functionality within tools leveraging this library within a container can lead increased privileges.

CVE-2022-4134

A flaw was found in openstack-glance. This issue could allow a remote, authenticated attacker to tamper with images, compromising the integrity of virtual machines created using these modified images.

CVE-2023-2088

A flaw was found in OpenStack due to an inconsistency between Cinder and Nova. This issue can be triggered intentionally or by accident. A remote, authenticated attacker could exploit this vulnerability by detaching one of their volumes from Cinder. The highest impact is to confidentiality.
