Name of the Vulnerable Software and Affected Versions
KubeVirt versions prior to 1.8.3-1.1
Description
A path traversal flaw exists in the
virt-exportserver component. An attacker with namespace-level access can exploit the 'VMExport directory' endpoint by placing a symbolic link (symlink) within an exported filesystem Persistent Volume Claim (PVC) that points outside its designated mount root. This allows the attacker to read arbitrary files from the exporter pod's filesystem, resulting in information disclosure of sensitive data.Recommendations
Update to version 1.8.3-1.1.
