Security Bulletin
Summary
There is a vulnerability in the Apache Log4j open source library. This library is not used within the MaaS360 Enterprise Gateway code, but is contained within the package of the MaaS360 Enterprise Gateway module. The Enterprise Gateway module is contained within the MaaS360 Cloud Extender agent, when the Enterprise Gateway service is enabled by a customer. The MaaS360 Cloud Extender agent and all other modules do not contain Java and therefore are not affected by this vulnerability. A remeditation is provided to remove the unused Apache Log4j library.
