- Affected component
- github.com/kubev2v/assisted-migration-agent (go)
- Affected versions
- < 0.16.0
- Patched version

An early warning has been issued for a path traversal vulnerability in the assisted-migration-agent that could allow an unauthenticated attacker to write arbitrary files and potentially execute remote code. Users of versions prior to 0.16.0 are reportedly at risk.
What happened
An early warning has been issued regarding a path traversal vulnerability in the assisted-migration-agent. This vulnerability, tracked as GHSA-7J4W-X8X8-5MVG, allows an unauthenticated attacker on the same local area network to bypass security checks and write arbitrary files. This could potentially lead to remote code execution. The vulnerability is present in versions of the agent prior to 0.16.0.
The vulnerability arises from improper handling of gzipped tarballs, which enables the path traversal attack. This issue has been reported but is not yet confirmed. It is under investigation and no exploits in the wild have been reported. Users are advised to monitor for patches and upgrade to a fixed version once it becomes available.
What to do about it
- Check the version of assisted-migration-agent in use. If it is prior to 0.16.0, you are potentially affected.
- Monitor the GitHub Advisory Database and other official sources for updates on this vulnerability.
- Upgrade to version 0.16.0 or later of assisted-migration-agent as soon as a patch is available.
- Implement network segmentation to limit the exposure of the agent to only necessary local area networks.
- Review and strengthen access controls and security checks for the assisted-migration-agent.
