"The version of Python installed on the remote Windows host is improper validation vulnerability.  The 
urllib.parse.urlsplit() and urlparse() functions improperly validated bracketed hosts (`[]`), allowing 
hosts that weren't IPv6 or IPvFuture. This behavior was not conformant to RFC 3986 and potentially 
enabled SSRF if a URL is processed by more than one URL parser.

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