RH-SSO handles empty POST data incorrectly while invoking admin REST interfaces

Solution Verified - Updated -

Issue

  • When making POST requests to /users and /groups REST interfaces with empty data RH-SSO returns HTTP/1.1 500 Internal server error.

  • RH-SSO currently produces an uncaught java.lang.NullPointerException with empty POST data while invoking admin REST interfaces which is not just an extremely bad programming style but a sign for unwanted after effects.

  • RH-SSO is vulnerable against bad requests with none/empty post data.

Environment

  • Red Hat Single Sign-On (RH-SSO)
    • 7.x
