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.\n\n## Affected packages\n\n- `github.com/kubev2v/assisted-migration-agent < 0.16.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/kubev2v/assisted-migration-agent 0.16.0`","depth":"midnight","depthScore":53,"depthScoreParts":{"impact":52.8,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
