The version of rust / tensorflow / curl / mysql installed on the remote CBL Mariner 2.0 host is prior to tested version.
It is, therefore, affected by a vulnerability as referenced in the CVE-2023-28321 advisory.
xn--
and should not be allowed to pattern match, but the wildcard check in curl could still check for x*
, which would match even though the IDN name most likely contained nothing even resembling an x
. (CVE-2023-28321)Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

It is, therefore, affected by a vulnerability as referenced in the CVE-2023-28321 advisory.
- An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of
wildcard patterns when listed as Subject Alternative Name in TLS server certificates. curl can be built
to use its own name matching function for TLS rather than one provided by a TLS library. This private
wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a
result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before
used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to
pattern match, but the wildcard check in curl could still check for `x*`, which would match even though
the IDN name most likely contained nothing even resembling an `x`. (CVE-2023-28321)
