Merge /Testing_for_Vertical_Bypassing_Authorization_Schema_WSTG-AUTHZ-00X.md into 4-Web_Application_Security_Testing/05-Authorization_Testing/03-Testing_for_Privilege_Escalation.md

Is there a way to skip the nmap scan and go straight to the attacking routes? In case i already know the target list is full of open rtsp port IPs.
