WBSP-AS-000940 - The WebSphere Application Server must remove JREs left by web server and plug-in installers for web servers and plugins running in the DMZ.

Information

When you install IBM HTTP Server, the installer leaves behind a JRE. Remove this JRE, as it provides functions that are not needed by the Web server or plug-in under normal conditions. Keep in mind that this will make it impossible to run some tools such as ikeyman on this Web server.

When you install the WebSphere Application Server HTTP Server plug-in using the IBM installer, it also leaves behind a JRE. Also, remove this JRE post install.

Having a functioning JRE in the DMZ provides attackers who have breached into the DMZ with additional tools to carry out further attacks.

Solution

For web servers provided with the WebSphere installation that are operating in the DMZ.

Remove the /java directory from within the plugins folder.
