Maybe I'm misunderstanding this newfangled internets but isn't exploitation generally synonymous with security vulnerability?

JFYI, for anyone who's interested, the equivalent debugging API methods in .NET could be found in ClrMd[0] but it's as unyielding a beast as the native methods.

A vulnerability is "this function will write 8 bytes of arbitrary data out of bounds in an edge case". Exploitation is the process of using that vulnerability to, typically, cause the process to execute attacker-controlled code.

Something can make exploitation easier without being a vulnerability. For example, disabling exploit mitigations like ASLR does this.
