A vulnerability was found in Wildflys Enterprise Java Beans (EJB) versions shipped with Red Hat JBoss EAP 7, where SessionOpenInvocations are never removed from the remote InvocationTracker after a response is received in the EJB Client, as well as the server. This flaw allows an attacker to craft a denial of service attack to make the service unavailable.

Weakness

The product does not release or incorrectly releases a resource before it is made available for re-use.

Potential Mitigations

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, languages such as Java, Ruby, and Lisp perform automatic garbage collection that releases memory for objects that have been deallocated.
