"The version of Curl installed on the remote host is between 8.6.0 and prior to 8.7.0. It is, therefore, affected by a
certificate check bypass vulnerability. libcurl skips the certificate verification for a QUIC connection under certain 
conditions, when built to use wolfSSL. If told to use an unknown/bad cipher or curve, the error path accidentally skips 
the verification and returns OK, thus ignoring any certificate problems.

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