Xapi Vulnerability in Citrix Hypervisor Allowing Malicious Metadata Backup Manipulation
CVE-2024-31144
3.8LOW
What is CVE-2024-31144?
The Xapi component in Citrix Hypervisor allows for backup and restoration of metadata related to Virtual Machines (VMs) and Storage Repositories (SRs). The metadata is stored in a Virtual Disk Image (VDI) and is critical for recovery scenarios. A malicious guest could exploit this functionality by manipulating its disk to imitate a legitimate metadata backup. Given that the restoration process involves searching VDIs in UUID order to locate the required metadata, a guest with one disk has an increased probability of being erroneously identified as the metadata VDI. This aspect could be exploited, leading to unauthorized access or manipulation of critical metadata.
