( ## Vulnerability Details Vulnerability 1: No authentication is required to interact with the Simple Diagnostic Agent http service on port 3005 by default. Therefore, unauthenticated attackers will have full access to either administrative or other privileged functionalities. Leveraging this access, they would be able to read, modify or delete sensitive information and configurations with sapadm OS user privileges.
