They are significant in cybersecurity because misconfigurations or vulnerabilities can expose internal resources to attackers, enabling unauthorized access, web shells, and persistence. The recent report on a flaw in ArrayOS AG VPN highlights the ongoing risk of SSL VPN vulnerabilities being weaponized and the need for prompt patching and monitoring.
