## Overview

A flaw was found in assisted-migration-agent. An unauthenticated attacker, located on the same local area network (LAN), can exploit a path traversal vulnerability. By crafting a specially designed gzipped tarball, the attacker can bypass security checks and write arbitrary files to the system. This could ultimately lead to the execution of unauthorized code on the appliance.

## Affected packages

- `github.com/kubev2v/assisted-migration-agent < 0.16.0`

## Remediation

Upgrade to a patched release:

- `github.com/kubev2v/assisted-migration-agent 0.16.0`
