ftp-srv is an open-source FTP server designed to be simple yet configurable. In ftp-srv before version 4.4.0 there is a path-traversal vulnerability. Clients of FTP servers utilizing ftp-srv hosted on Windows machines can escape the FTP user's defined root folder using the expected FTP commands, for example, CWD and UPDR. When windows separators exist within the path (`\`), `path.resolve` leaves the upper pointers intact and allows the user to move beyond the root folder defined for that user. We did not take that into account when creating the path resolve function. The issue is patched in version 4.4.0 (commit 457b859450a37cba10ff3c431eb4aa67771122e3).

Affected: npm: ftp-srv

### Impact

Clients of FTP servers utilizing `ftp-srv` hosted on Windows machines can escape the FTP user's defined root folder using the expected FTP commands, for example, `CWD` and `UPDR`.

### Background

When windows separators exist within the path (`\`), `path.resolve` leaves the upper pointers intact and allows the user to move beyond the root folder defined for that user. We did not take that into account when creating the path resolve function.

### Patches None at the moment.

### Workarounds There are no workarounds for windows servers. Hosting the server on a different OS mitigates the issue.
