WinSCP 6.5.7 Build 16562/ 6.6.3.17667 RC

WinSCP is an open source freeware SFTP client, FTP client, WebDAV client and SCP client. Its main function is safevfile transfer between a local and a remote computer,  using SSH (Secure Shell).

Beyond those basic functions, WinSCP offers scripting and basic file manager functionality. The application also allows you to rename files and folders, create new folders, change properties of files and folders.

One of two selectable program interfaces allows user to manage files even on local computer. Most operations you can do recursively for files in folders.

WinSCP is also available as a plugin to two file managers, FAR and Servant Salamander.

WinSCP Features:

• Integration with Windows (drag and drop, URL, shortcut icons)
• Graphical user interface
• Translated into several languages
• All common operations with files
• Support for SFTP and SCP protocols over SSH-1 and SSH-2
• Batch file scripting and command-line interface
• Directory synchronization in several semi or fully automatic ways
• Integrated text editor
• Support for SSH password, keyboard-interactive, public key and Kerberos (GSS) authentication
• Integrates with Pageant (PuTTY authentication agent) for full support of public key authentication

  It brings the following change:
  • Security issue: fixed a remotely triggerable use-after-free in Pageant.
  • Security issue: fixed a remotely triggerable buffer overflow if the OpenSSH encrypt-then-MAC cipher modes are in use.
  • Security issue: fixed a buffer overflow in private key decryption, if the private key is constructed maliciously.
  • Denial-of-service security fixes: a server can trigger a tight loop in WinSCP, and even a MITM can make it consume unlimited memory at startup.
  • Security issue: fixed a remotely triggerable double-free in RSA key exchange.
  • Minor security issue: fixed a remotely triggerable crash in NIST ECDSA signature verification.
• Back-propagated fixes from 6.6.2 beta release:
  • Bug fix: Failure setting Session.DebugLogPath when running in impersonated context.
• Bug fix: A specially crafted PKCS#7 or S/MIME signed message could trigger a use-after-free during PKCS#7 signature verification. CVE-2026-45447 fix from OpenSSL 3.4.6.

Server Requirements

Using WinSCP, you can connect to an SSH (Secure Shell) server with SFTP (SSH File Transfer Protocol) or SCP (Secure Copy Protocol) service, to an FTP (File Transfer Protocol) server or HTTP server with WebDAV service.SFTP is a standard part of the SSH-2 package. SCP is a standard part of the SSH-1 package. You can also run both protocols on the latter SSH version. WinSCP supports both SSH-1 and SSH-2. For authentication, you can use user name and password or public key (RSA or DSA). Other authorization types include TIS, Cryptocard, Keyboard-interactive, and Kerberos.For FTP, both the basic unencrypted variant and FTPS are supported. Compressed transfers (Zlib) are not supported.

For WebDAV, both the basic unencrypted variant and WebDAVS are supported. Compressed transfers (Zlib) are not supported.

SFTP Requirements

For SFTP, the only requirement beyond the server requirements above is to run SFTP on the server. It is best to run it as an SSH-2 subsystem. If you select SFTP-only on the Login dialog and the SFTP subsystem is not found, WinSCP will try to find the SFTP server in some common directories (/usr/lib/sftp-server, /usr/local/lib/sftp-server, etc.). This way, it is possible to use SFTP even with SSH-1, which does not support subsystems.
