Which kind of server is often the launching point into a targets network and has known vulnerabilities?

The kind of server often used as a launching point into a target's network is the web server. Web servers frequently host applications that may have known vulnerabilities, such as outdated software, misconfigurations, or exposed sensitive data. Attackers exploit these vulnerabilities to gain initial access to the network, allowing them to escalate privileges and move laterally within the system. Regular patching and security assessments are crucial to mitigate these risks.
