Root Cause Analysis
The vulnerability stems from missing impersonation checks in SASL authorization handlers. The patches add 'impersonationAllowed' flags to ServerCallbackHandlers
across authentication mechanisms (Kerberos/Digest/Plain). The handleAuthorizeCallback
methods in these classes previously processed authorization requests without validating if the server configuration permitted impersonation. During exploitation, these functions
would appear in stack traces as they directly handle user authentication/authorization and would process malicious impersonation attempts.
