"The version of IBM HTTP Server running on the remote host is affected by a vulnerability. 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
