In several versions of JetBrains IntelliJ IDEA Ultimate, creating run configurations for cloud application servers leads to saving a cleartext unencrypted record of the server credentials in the IDE configuration files. If the Settings Repository plugin was then used and configured to synchronize IDE settings using a public repository, these credentials were published to this repository. The issue has been fixed in the following versions: 2019.1, 2018.3.5, 2018.2.8, and 2018.1.8.
In several versions of JetBrains IntelliJ IDEA Ultimate, creating Task Servers configurations leads to saving a cleartext unencrypted record of the server credentials in the IDE configuration files. The issue has been fixed in the following versions: 2019.1, 2018.3.5, 2018.2.8, and 2018.1.8.
In several JetBrains IntelliJ IDEA Ultimate versions, an Application Server run configuration (for Tomcat, Jetty, Resin, or CloudBees) with the default setting allowed a remote attacker to execute code when the configuration is running, because a JMX server listened on all interfaces instead of localhost only. The issue has been fixed in the following versions: 2018.3.4, 2018.2.8, 2018.1.8, and 2017.3.7.
