Description Martin Prpič 2016-11-01 05:56:47 EDT 
The following flaw was found in Tomcat:

When a SecurityManager is configured, a web application's ability to read system properties should be controlled by the SecurityManager. Tomcat's system property replacement feature for configuration files could be used by a malicious web application to bypass the SecurityManager and read system properties that should not be visible.
