Assisted Migration Agent: Path traversal in gzipped tarball handling enables arbitrary file write and remote code execution
Impact
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.
