Wing FTP Server does not verify user's base folder. An attacker with admin privileges can add user directories via scripts, allowing the added directories to escape the base folder. This allows the attacker to write files on the system and can lead to remote code execution with process owner privileges.Critically, since the installation guide mentions running the command with sudo, the files are created as “root.”
This issue was fixed in version 8.2.6.
