Cvss 3 Severity Score

7.5 · High

Score breakdown

The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.

mdeslaur

DES ciphers aren't typically selected as there are other stronger ciphers placed earlier in default cipher lists gnutls puts AES before 3DES in the cipher list
