Description
Open Access Management (OpenAM) is an access management solution. Prior to 16.1.1, GroovySandboxValueFilter permits an authenticated server-side script author to escape the scripting sandbox despite the default class allow and deny lists. A user such as a sub-realm RealmAdmin who can create or edit a script in an executed context can invoke operating-system commands as the OpenAM application server account, crossing the realm-scoped administration boundary and compromising the JVM and every realm it serves. This issue is fixed in version 16.1.1.
