Frequently Asked Questions
What is the issue?
Researchers have announced SSL/TLS vulnerability called the FREAK attack. It allows an attacker to intercept SSL/TLS connections between vulnerable clients and servers and force them to use weakened encryption, which the attacker can break to steal or manipulate sensitive data. The vulnerability concerns SSL/TLS cipher suites that use export-grade RSA keys, which are intentionally weakened to comply with (now defunct) US export control laws.

What components of Syncplicity are affected?
The issue may impact customers’ deployment of the Syncplicity Storage Connector and Syncplicity Panorama Connector. Servers with RSA export cipher suites enabled are vulnerable to the FREAK attack. By default, Syncplicity Storage Connector and Syncplicity Panorama connector do not enable the RSA Export cipher suites; however, customers may have configured their servers with RSA Export cipher suites enabled.
Is Syncplicity’s cloud service vulnerable to this issue?
Syncplicty’s cloud service is not impacted by this vulnerability. Syncplicity servers (my.syncplicity.com, www.syncplicity.com, data.syncplicity.com, xml.syncplicity.com) do not support export-grade cipher suites.
What steps do customers need to take to address the vulnerability?
There is no action needed by EMC Syncplicity Personal Edition, Business Edition, and Enterprise Edition cloud storage only customers to address this vulnerability.
Customers that have configured a Syncplicity On-Premise Storage Connector for SSL are advised as follows:
- Check your server configuration with a utility such as Qualys SSL Labs SSL Server Test tool to determine if your server supports TLS export cipher suites such as the following:
(note: not an exhaustive list of export ciphers)
- Ensure you are running Syncplicity Storage Connector version 184.108.40.206 or greater. Type the following command to determine which Storage Connector version is installed:
yum info syncp-storage | grep Version
The version number that appears should be 220.127.116.11 or greater.
- If you are not running Syncplicity Storage Connector version 18.104.22.168 or greater, upgrade the Storage Connector using the instructions documented here:
- Migrate from stunnel using the steps described in Chapter 2 “Configuring SSL” of the Storage Connector SSL Configuration Guide linked here:
https://my.syncplicity.com/share/dd0vash0ashw4gw/Syncplicity On-Premise Storage Connector SSL Configuration Guide
The vulnerable export ciphers are disabled by default and should not be enabled.
Syncplicity Panorama Connector customers are advised as follows:
Syncplicity Panorama customers should review the Microsoft Security Bulletin,
