If an old server absolutely cannot be decommissioned due to legacy dependencies: Place it behind a strict firewall.

Security researchers upload scripts (often in Python or Ruby) to demonstrate that a vulnerability exists. These are intended for educational purposes and authorized penetration testing. 2. Metasploit Modules
