Description
JuggleIM im-server through 1.8.16 ships default administrator credentials admin/123456 that allow unauthenticated remote attackers to access the admin console on port 8090. Attackers can log in as administrator, even after account deletion since CheckLogin recreates it, to control tenant applications and app secrets.
