Apache CloudStack's userdata-related APIs, including those for managing virtual machines and user data, are vulnerable due to insufficient access control, potentially allowing unauthorized access to sensitive userdata across different tenants. This could lead to exposure of sensitive information and unauthorized actions within the cloud environment. Organizations using affected versions (4.18.0.0 to 4.20.3.0 and 4.21.0.0 to 4.22.1.0) should prioritize upgrading to versions 4.20.3.1 or 4.22.1.1 or later to mitigate this risk.

Original NVD Description

Missing Authorization, Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache CloudStack's Userdata reference APIs. Several userdata-related APIs in Apache CloudStack, including deleteUserData, linkUserDataToTemplate, resetUserDataForVirtualMachine, deployVirtualMachine, and updateVirtualMachine, exhibit missing or insufficient access control validation, potentially allowing cross-tenant/cross-account access to userdata resources that belong to other tenants. This issue affects Apache CloudStack: from 4.18.0.0 through 4.20.3.0 and from 4.21.0.0 through 4.22.1.0. The deleteCniConfiguration API, introduced in 4.21.0.0, also exhibits similar behaviour and lacks access validation. Users are recommended to upgrade to version 4.20.3.1 or 4.22.1.1 or later, which fixes the issue.
