This technique is called: key exchange with key encryption. There is no place for MITM (Man-In-The-Middle) attack, because an attacker cannot decrypt encrypted key as he do not have access to private key (which is held by server only). This key exchange mechanism may have security issues. Only one peer has control over session key generation.
SSL key exchange with and without encryption - PKI Extensions This technique is called: key exchange with key encryption. There is no place for MITM (Man-In-The-Middle) attack, because an attacker cannot decrypt encrypted key as he do not have access to private key (which is held by server only). This key exchange mechanism may have security issues. Only one peer has control over session key generation. Ratcheted Encryption and Key Exchange The key for encryption and decryption is what ratcheted key exchange referred to as the output key. Besides a natural correctness requirement, we have a robustness requirement: if the receiver receives an update that it rejects, it maintains its state and will still accept a subsequent correct 3 Email Message Encryption - Office 365 Provide and manage your own encryption keys with Bring Your Own Key for Azure Information Protection.

A.2. Public-key Encryption Red Hat Enterprise Linux 7
Internet Key Exchange (IKE) is a key management protocol standard used in conjunction with the Internet Protocol Security (IPSec) standard protocol. It provides security for virtual private networks' (VPNs) negotiations and network access to random hosts. It can also be described as a method for exchanging keys for encryption and
But as a key exchange mechanism, public key encryption eliminates a lot of attack vectors. And owing to its one-way nature, the Private keys used in public key encryption can be a lot more robust. A strong symmetric private key is 256 bits. That is still plenty of security. But it pales in comparison to a 2048-bit RSA private key. Public-Key Encryption - Basic Key Exchange | Coursera Key exchange using public key cryptography, and key exchange using the Diffie-Hellman. You can take a look at this paper and it kind of will give you a look ahead into what's coming and how to make these key exchange protocols secure against man in the middle and not just secure against eavesdropping. encryption - DEK, KEK and Master key - simple explanation
