Technical Description
zrok is software for sharing web services, files, and network resources. From 0.4.23 until 2.0.3, `zrok2 copy` stores attacker-controlled WebDAV or zrok drive paths such as /../outside.txt in the source inventory and passes them to FilesystemTarget.WriteStream, allowing the sync pipeline to write files outside the selected local filesystem destination root. This issue is fixed in version 2.0.3.
Remediation
Check the references section for vendor advisories and patches from netfoundry. Update zrok to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
