Security readout for executives and security teams

CVE-2016-6521 affects Grails Console, also called Grails Debug Console or Grails Web Console. A malicious site could abuse a logged-in console user's browser to submit requests that execute Groovy code. If that console is reachable in production, the business impact could be severe. Exposure is likely limited to applications that installed and exposed Grails Console, Grails Debug Console, or Grails Web Console in affected versions. Risk is highest where the console is reachable by browsers used by authenticated developers or operators. Treat as urgent where the console exists in production or shared environments. If the component is absent or only present in isolated development systems, priority is lower but inventory should be confirmed. Mitigation focus: Check the Grails Console project guidance and referenced issues for fixed versions or removal advice.; Remove or disable Grails Console from production deployments.; Restrict console access to trusted administrative networks only..
