IO#read returns nil for an empty file if given a length argument, which
caused a stack trace when attempting to import a file instead of a
useful error message.

Move Msf::DBManager#import_msf_xml into
Msf::DBManager::ImportMsfXml#import_msf_xml and include
Msf::DBManager::ImportMsfXml to cut down size of the infamous db.rb.
Break up #import_msf_xml to have separate methods for parsing web_forms,
web_pages, and web_vulns. The method for
web_vulns, #import_msf_web_vuln_element is needed so that it can be overridden in
Pro to handle the Pro-only changes to Mdm::WebVuln.
This commit fixes an Encoding::CompatibilityError incompatible
encoding regexp match (ASCII-8BIT regexp with UTF-8 string) when
sanitizing non-printable tokens from a user/pass string.
The UTF-8 strings are derived from strings passed through the
module.execute RPC call.
db.rb assumes that multi/handler sessions have a ParentModule defined
in their datastore. This assumption breaks when a user sets up a
multi/handler by hand to receive a session from another user (e.g.,
via multi_meter_inject).
When db.rb tries to access a member of a nil ParentModule, a
stacktrace is dumped to framework.log.
[fixes RM7269]
we discussed the solution to this bug a lot on IRC and in the ticket
itself, the consensus was to fix it as far upstream as possible before
sending to the parsers so as to avoid any future bugs of the same
nature, so this commit adds a check to import_nmap_xml to see if the
data is empty before passing it on to the parser, whether that parser
is nokogiri or the legacy parser.
db_nmap -h now produces the expected output and db_nmap still works as
expected.
Netsparker puts requests, responses, and info for vulns inside a cdata
(which makes sense because it's usually html snippets). This commit
handles that so report_web_vuln will actually be somewhat useful. Note
that the request is ignored by report_web_vuln despite there being a
place for it in the WebVuln model.
[SeeRM #7665]
[SEERM #7294]
[Bug #40937817]
* exploit/multi/handler no longer filtered out from vuln creation and
other steps
* Name changed to parent module's name in session storage so we show something more helpful
than generic handler
* Same for vuln and attempt creation
This also fixes an issue with report_vuln() from exploited hosts not
setting the service correctly. This introduces a fail_reason method
to the exploit base class, which attempts to determine why an exploit
did not work (closed port, unreachable host, missing page, etc). There
is still quite a bit of work to do around this to finish it up.
