What is the issue?
This vulnerability allows the plaintext of secure connections to be calculated by a network attacker. In the web setting, this SSL 3.0 weakness can be exploited by a maninthe-middle attacker to decrypt “secure” HTTP cookies, using techniques from the BEAST attack.

What components of Syncplicity are affected?
The issue impacts the Syncplicity web site (www.syncplicity.com), Syncplicity cloud storage, and Syncplicity On-Premise Storage Connector.
What steps were taken to remediate the vulnerability?
Support for SSL 3.0 has been removed from the Syncplicity web site (www.syncplicty.com) and Syncplicity cloud storage.
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 customers to address this vulnerability.
EMC Syncplicity Enterprise Edition on-premise administrators are advised as follows:
If the Storage Connector Compute Node is configured with SSL using stunnel, administrators should check the configuration and remove SSL 3.0 protocol option if it is presently specified. Perform the following steps to update the stunnel config.
- Edit etc/stunnel/stunnel.conf.
- Update the following line. Possible values are (all, SSLv2, SSLv3, TLSv1)
sslVersion = SSLv3
The suggested value is TLSv1:
sslVersion = TLSv1
- Restart stunnel service by executing command –
sudo service stunnel restart
If your Storage Connector is situated behind an SSL load-balancer we recommend you disable support for SSL 3.0 per the steps recommended by your load-balancer vendor.
