Is Cryptshare affected by this vulnerability?

The Cryptshare products are not affected by the Log4Shell vulnerability. 

We have checked the use of the affected software components for all Cryptshare products. This applies to the entire product range (Cryptshare Server, Cryptshare for Outlook with Cryptshare Config Creator, Cryptshare for OWA, Cryptshare for Notes, Cryptshare Robot, Cryptshare Java API, Cryptshare .NET API, Cryptshare for NTA 7516) for both current and out-of-date versions.

In Cryptshare Server (current version: 5.1.0) Log4J was in use until version 3.10.3 (release date 30.05.2016), but in a version that is not affected by the security vulnerability.

Important note regarding the Cryptshare Software Development Kit (SDK)

Please note, however, that our Software Development Kit (SDK) includes a third-party mail server (Apache James) which is affected by the vulnerability. We are making the SDK available to customers who would like to try out the possibilities of automation with Cryptshare on a trial basis via our website. If the SDK is used as intended, this does not pose a risk, as the components of the SDK are not used productively and should not be accessible from the Internet. 

If you are using the Cryptshare SDK for the test implementation of an automation, ensure this intended use or refrain from using the test environment for the time being. An update for the SDK will be provided after a suitable fix for the included third-party components is available.

Productive automations using Java API, .NET API or Cryptshare Robot are not affected.
