Re: Apache Log4j vulnerability

Appgate SDP v5.1.x - v5.5.x are NOT affected by the Log4j vulnerability.

While the log4j library is included in the Appgate SDP appliance build, its ONLY use is in the open source Elasticsearch component of the LogServer. Elastic has confirmed that Elasticsearch is NOT affected by the Log4j vulnerability (but have identified a related minor information leakage issue). Versions 5.4.6 and 5.5.2 contain the updated 2.17.1 version of Log4j.
We strongly recommend that our secure deployment recommendations are followed - specifically that the LogServer should never be exposed to the internet, but only accessible to other components of the SDP system and to authorized, authenticated users.
