Account users in Apache CloudStack by default are allowed to register templates to be downloaded directly to the primary storage for deploying instances. Due to missing validation checks for KVM-compatible templates in CloudStack 4.0.0 through 4.18.2.4 and 4.19.0.0 through 4.19.1.2, an attacker that can register templates, can use them to deploy malicious instances on KVM-based environments and exploit this to gain access to the host filesystems that could result in the compromise of resource integrity and confidentiality, data loss, denial of service, and availability of KVM-based infrastructure managed by CloudStack. Users are recommended to upgrade to Apache CloudStack 4.18.2.5 or 4.19.1.3, or later, which addresses this issue. Additionally, all user-registered KVM-compatible templates can be scanned and checked that they are flat files that should not be using any additional or unnecessary features. For example, operators can run the following command on their file-based primary storage(s) and inspect the output. An empty output for the disk being validated means it has no references to the host filesystems; on the other hand, if the output for the disk being validated is not empty, it might indicate a compromised disk. However, bear in mind that (i) volumes created from templates will have references for the templates at first and (ii) volumes can be consolidated while migrating, losing their references to the templates. • https://cloudstack.apache.org/blog/security-release-advisory-4.18.2.5-4.19.1.3 https://lists.apache.org/thread/d0x83c2cyglzzdw8csbop7mj7h83z95y https://www.shapeblue.com/shapeblue-security-advisory-apache-cloudstack-security-releases-4-18-2-5-and-4-19-1-3 • CWE-20: Improper Input Validation •

Account users in Apache CloudStack by default are allowed to upload and register templates for deploying instances and volumes for attaching them as data disks to their existing instances. Due to missing validation checks for KVM-compatible templates or volumes in CloudStack 4.0.0 through 4.18.2.3 and 4.19.0.0 through 4.19.1.1, an attacker that can upload or register templates and volumes, can use them to deploy malicious instances or attach uploaded volumes to their existing instances on KVM-based environments and exploit this to gain access to the host filesystems that could result in the compromise of resource integrity and confidentiality, data loss, denial of service, and availability of KVM-based infrastructure managed by CloudStack.

The CloudStack Quota feature allows cloud administrators to implement a quota or usage limit system for cloud resources, and is disabled by default. In environments where the feature is enabled, due to missing access check enforcements, non-administrative CloudStack user accounts are able to access and modify quota-related configurations and data. This issue affects Apache CloudStack from 4.7.0 through 4.18.2.3; and from 4.19.0.0 through 4.19.1.1, where the Quota feature is enabled. Users are recommended to upgrade to Apache CloudStack 4.18.2.4 or 4.19.1.2, or later, which addresses this issue. Alternatively, users that do not use the Quota feature are advised to disabled the plugin by setting the global setting "quota.enable.service" to "false". La función Cuota de CloudStack permite a los administradores de la nube implementar un sistema de cuota o límite de uso para los recursos de la nube y está deshabilitada de forma predeterminada. • https://cloudstack.apache.org/blog/security-release-advisory-4.18.2.4-4.19.1.2 https://lists.apache.org/thread/ktsfjcnj22x4kg49ctock3d9tq7jnvlo • CWE-269: Improper Privilege Management •

The logout operation in the CloudStack web interface does not expire the user session completely which is valid until expiry by time or restart of the backend service. An attacker that has access to a user's browser can use an unexpired session to gain access to resources owned by the logged out user account. This issue affects Apache CloudStack from 4.15.1.0 through 4.18.2.3; and from 4.19.0.0 through 4.19.1.1. Users are recommended to upgrade to Apache CloudStack 4.18.2.4 or 4.19.1.2, or later, which addresses this issue. La operación de cierre de sesión en la interfaz web de CloudStack no hace que la sesión del usuario caduque por completo, lo que es válido hasta que caduque por tiempo o se reinicie el servicio de backend. Un atacante que tenga acceso al navegador de un usuario puede usar una sesión vigente para obtener acceso a los recursos que posee la cuenta de usuario que cerró la sesión. • https://cloudstack.apache.org/blog/security-release-advisory-4.18.2.4-4.19.1.2 https://lists.apache.org/thread/ktsfjcnj22x4kg49ctock3d9tq7jnvlo • CWE-613: Insufficient Session Expiration •

Users logged into the Apache CloudStack's web interface can be tricked to submit malicious CSRF requests due to missing validation of the origin of the requests. This can allow an attacker to gain privileges and access to resources of the authenticated users and may lead to account takeover, disruption, exposure of sensitive data and compromise integrity of the resources owned by the user account that are managed by the platform. This issue affects Apache CloudStack from 4.15.1.0 through 4.18.2.3 and 4.19.0.0 through 4.19.1.1 Users are recommended to upgrade to Apache CloudStack 4.18.2.4 or 4.19.1.2, or later, which addresses this issue. Los usuarios que hayan iniciado sesión en la interfaz web de Apache CloudStack pueden ser engañados para que envíen solicitudes CSRF maliciosas debido a la falta de validación del origen de las solicitudes. Esto puede permitir que un atacante obtenga privilegios y acceso a los recursos de los usuarios autenticados y puede provocar la apropiación de cuentas, interrupciones, exposición de datos confidenciales y comprometer la integridad de los recursos propiedad de la cuenta de usuario que son administrados por la plataforma. Este problema afecta a Apache CloudStack desde la versión 4.15.1.0 hasta la 4.18.2.3 y desde la versión 4.19.0.0 hasta la 4.19.1.1. • https://cloudstack.apache.org/blog/security-release-advisory-4.18.2.4-4.19.1.2 https://lists.apache.org/thread/ktsfjcnj22x4kg49ctock3d9tq7jnvlo • CWE-352: Cross-Site Request Forgery (CSRF) •
