"This server is vulnerable to a SWEET32 attack. Make sure the weak ciphers (DES and 3DES) are disabled on the server and use AES."
The Sweet32 Birthday attack, affects the triple-DES cipher. Although the OpenSSL team rated the triple-DES vulnerability as low, they stated “triple-DES should now be considered as ‘bad’ as RC4.” DigiCert security experts as well as other security pros recommend disabling any triple-DES cipher on your servers.
The triple-DES cipher is supported by a vast majority of HTTPS servers and all major web browsers—around 600 of the most-visited websites. Fortunately, most browsers opt to use AES rather than triple-DES when making an HTTPS connection.
