Upgrade to v6.2.21 now (and be safe from the Terrapin Attack)
Every once in a while something happens that shakes up an entire industry. This is one such time.
The Terrapin Attack (CVE-2023-48795) affected practically every SSH server from every vendor on the planet. And though the bug wasn't in our own code, we inherited it from Go's ssh package, so our server software ended up being affected as well.
Kudos to the Go developers who identified and fixed the issue before the CVE was even made public! We will be forever grateful to them, as their timeliness allowed us to release v6.2.21 before this problem affected any of our customers.
We did our part, now it's all up to you: to make sure your Syncplify Server! is protected from the Terrapin Attack, please, upgrade to v6.2.21+ with the utmost level of urgency. Thank you!
