Syncplify Server! v6.2.36 released

Importance of this update: [MINOR]
What’s changed?
  • Fixed a couple of glitches in the Admin UI

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.

Syncplify Server! is *NOT* vulnerable to CVE-2024-6387

OpenSSH, a widely used secure shell-protocol handling software, has recently disclosed a critical vulnerability (CVE-2024-6387) affecting its server component. This flaw could potentially allow unauthenticated remote code execution with root privileges on glibc-based Linux systems. The vulnerability, present in OpenSSH versions 8.5p1 through 9.7p1, is a signal handler race condition that affects the default configuration of sshd.

Qualys researchers have identified over 14 million potentially vulnerable OpenSSH server instances exposed to the internet[1]. While exploitation requires continuous connections for 6-8 hours under lab conditions, the potential impact is severe, allowing full system compromise and takeover.

It’s important to note that Syncplify Server! is not affected by this vulnerability. Unlike many other SSH servers, Syncplify Server! is not based on OpenSSH in any way. This independent implementation ensures that Syncplify Server! users are protected from vulnerabilities specific to OpenSSH, including CVE-2024-6387.

For those using OpenSSH, it’s crucial to apply the latest patches promptly. Additionally, limiting SSH access through network-based controls and enforcing network segmentation can help mitigate potential risks.

Syncplify Server! v6.2.35 released

Importance of this update: [HIGH]
What’s changed?
  • Updated the back-end SyngoDB database server to v4.11.2, which fixes a session persistence issue
  • Fixed a glitch in the Admin UI which prevented some settings from being correctly saved into the back-end database
  • Improved validators, so that certain “bad configurations” (leading to potential vulnerabilities) will no longer be accepted by the software

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.

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.

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
