Go to dashboardWing FTP Server does not verify that a user's base folder stays inside its allowed path. An attacker with admin rights can add user directories through scripts that escape the base folder, write arbitrary files, and reach remote code execution with the server's privileges, which can be root if the server was started with sudo.

Sites running Wing FTP Server before 8.2.6, especially installs started with sudo as the guide suggests, because files then land as root. Exposure requires admin access to the server, so the risk is highest where many people hold admin rights or admin credentials are weak. Teams not running Wing FTP Server can skip it.

8.2.68.2.6 or laterEach row is the first time that source carried this signal. The analyst’s rows are its own findings.
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.
