Apache CloudStack Security Releases 4.18.1.1 and 4.19.0.1

Apache CloudStack security releases 4.18.1.1 and 4.19.0.1 address the CVEs listed below. Affected users are recommended to upgrade their CloudStack installations.

CVE-2024-29006: x-forwarded-for HTTP header parsed by default

Severity: moderate

Description: By default the CloudStack management server honours the x-forwarded-for HTTP header and logs it as the source IP of an API request. This could lead to authentication bypass and other operational problems should an attacker decide to spoof their IP address this way.

Affected versions: Apache CloudStack 4.11.0.0 through 4.18.1.0, and 4.19.0.0

Severity: moderate

Affected versions: Apache CloudStack 4.9.1.0 through 4.18.1.0, and 4.19.0.0

Description: The CloudStack management server and secondary storage VM could be tricked into making requests to restricted or random resources by means of following 301 HTTP redirects presented by external servers when downloading templates or ISOs. Users are recommended to upgrade to version 4.18.1.1 or 4.19.0.1, which fixes this issue.

CVE-2024-29008: The extraconfig feature can be abused to load hypervisor resources on a VM instance

Severity: critical

Affected versions: Apache CloudStack 4.14.0.0 through 4.18.1.0, and 4.19.0.0

Description: A problem has been identified in the CloudStack additional VM configuration (extraconfig) feature, which can be misused by anyone who has the privilege to deploy a VM instance or configure settings of an already deployed VM instance to configure additional VM configuration even when the feature is not explicitly enabled by the administrator. In a KVM-based CloudStack environment, an attacker can exploit this issue to attach host devices, such as storage disks, and PCI and USB devices, such as network adapters and GPUs, in a regular VM instance that can be further exploited to gain access to the underlying network and storage infrastructure resources and access any VM instance disks on the local storage.
