Class OgnlSecurityManager

  • @Deprecated
public class OgnlSecurityManager
extends java.lang.SecurityManager
    Deprecated.
    will be removed in 3.5.x
    Wraps current security manager with JDK security manager if is inside OgnlRuntime user's methods body execution.

    Add the `-Dognl.security.manager` to JVM options to enable.

    Note: Due to potential performance and concurrency issues, try this only if you afraid your app can have an unknown "expression injection" flaw or you afraid you cannot prevent those in your app's internal sandbox comprehensively e.g. you cannot discover and maintain all attack vectors over time because of many dependencies and also their change over time.

    This tries to provide an option to you to enable a security manager that disables any sensitive action e.g. exec and exit even if attacker had a successful "expression injection" in any unknown way into your app. However, also honors previous security manager and policies if any set, as parent, and rolls back to them after method execution finished.

    Since:
    3.1.24
