AI Analysis
Technical Summary
The CloudStack Backup plugin in Apache CloudStack versions 4.21.0.0 and 4.22.0.0 contains an access control flaw (CWE-359) that allows any authenticated user with access to certain APIs to create new virtual machines from backups owned by other users. This improper access logic leads to exposure of private personal information by enabling unauthorized use of backup data. The vulnerability is addressed by upgrading to version 4.22.0.1, which corrects the access control mechanism in the plugin.
Potential Impact
Authenticated users with API access in affected CloudStack environments can misuse backup data from other users to create new virtual machines, leading to unauthorized exposure of private personal information. This compromises data confidentiality within the affected CloudStack deployment. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users of the CloudStack Backup plugin on versions 4.21.0.0 and 4.22.0.0 should upgrade to Apache CloudStack version 4.22.0.1, which contains the fix for this vulnerability. Patch status is not explicitly confirmed in the vendor advisory, but the recommended upgrade version addresses the issue. No additional mitigations are specified.
