Grandstream GXP1600 series firmware 1.0.4.152 and below is vulnerable to authenticated remote command execution when an attacker uploads a specially crafted tar file to the HTTP /cgi-bin/upload_vpntar interface.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
