Assisted-migration-agent: vddk tarball chained-symlink arbitrary file write_CVE-2026-53476

{
    "lastseen": "",
    "description": "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.",
