Syncplify Server! Users: Rest Easy, You’re Safe from the XZ Vulnerability

Heads up, admins! A recently discovered vulnerability in the XZ library has system administrators scrambling to patch their SFTP servers. This vulnerability could grant unauthorized access to affected Linux systems – not a fun situation.

But here’s some good news for Syncplify Server! users: you can breathe easy. Syncplify Server! does not utilize the XZ library, meaning your SFTP (and SSH2) server is completely unaffected by this specific exploit.

At Syncplify, security is paramount. We understand the critical role secure file transfer plays in your organization, and we take every precaution to ensure your data remains protected. This isn’t the first time Syncplify has proven its commitment to security:

  • Our software remained unscathed by the Heartbleed bug in 2014.
  • The Terrapin exploit discovered in 2023 posed no threat to Syncplify users.
  • And now, you can add the XZ library vulnerability to the list of non-issues for Syncplify Server! users.

This focus on security is what makes Syncplify the trusted choice for system administrators worldwide.

Syncplify Server! v6.2.30 released

Importance of this update: [WORKAROUND]
What’s changed?
  • Implemented a work-around to gracefully handle buggy SFTP clients that attempt multi-phase authentication in the wrong order (not the order explicitly mandated by the SSH2 protocol standard); most of these situations will now be handled internally by Syncplify Server! while maintaining session consistency at the same time

IMPORTANT NOTE: those who are running the “worker” system service under a different account (not System or LocalSystem) will need to re-configure the service to run under such account after upgrading from any version number <= 6.1.12)

Upgrading from v6.x.y is a simple and fairly automatic process: simply download the latest version from the official download page, and install it over the existing version, all of your settings and license will be kept.

If, instead, you’re upgrading from an older (v4/v5) version, you find the upgrade instructions in our knowledge base.

Syncplify Server! v6.2.29 released

Importance of this update: [MINOR]
What’s changed?
  • Fixed a small bug in DNS record resolution that only affected the Windows version of our software, and only when the operating system’s DNS configuration was wrong in the first place

Syncplify Server! v6.2.28 released

Importance of this update: [OPTIONAL]
What’s changed?
  • Restored support for PKI authentication (SSH2/SCP/SFTP) using insecure RSA keys (SHA1 signature, insecure moduli, …), while secure RSA keys have never been dropped. We understand that transitioning to secure keys can be a challenge for some users. While we’ve provided resources and recommendations for dropping RSA keys for PKI authentication and switching to more secure keys (ECDSA, Ed25519, …), we recognize that some users may require more time, hence the choice to re-enable PKI auth support for these insecure keys. This does not make our server software less secure, it simply means it may allow certain insecure algorithms, but security-conscious users will simply configure our server software not to use them, thus keeping it completely safe and secure
