Explanation

The vulnerability described in the question relates to a hard-coded session key in both the client and server applications, which is a security risk. Hard-coding cryptographic keys in source code exposes them to potential attackers who could extract them through reverse engineering or other The Diffie-Hellman (DH) algorithm is the most effective way to mitigate this vulnerability. DH is a key exchange algorithm that allows two parties (the client and the server) to securely establish a shared session key over an insecure channel, without ever transmitting the key itself. This means that, instead of hard-coding a session key, the client and server can use DH to dynamically generate the session key during the connection establishment, which is much more secure. Once the session key is generated via DH, it can be used for encrypting the communication between the client and server, and because the key is not hard-coded, it eliminates the vulnerability of key exposure.
