* Task constraint now optional, so no need for filler
* Task ID now in service_data so it's passed to the core and the login
creation methods
Note that there are some cases of host-endian left, these
are intentional because they operate on host-local memory
or services.
When in doubt, please use:
```
ri pack
```
Ruby treats endianess in pack operators in the opposite way
of python. For example, using pack('<I') actually ignores the
endianess specifier. These need to be 'I<' or better yet, 'V'.
The endian specify must occur after the pack specifier and
multiple instances in meterpreter and exe generation were
broken in thier usage.
The summary:
Instead of I/L or I< use V
Instead of I/L or I> use N
For Q, you need to always use Q< (LE) or Q> (BE)
For c/s/l/i and other lowercase variants, you probably dont
need or want a *signed* value, so stick with vV nN and cC.
JodaZ reported that the handle_connection() sock.put call can
result in the entire reverse_tcp stager hanging if the client
stops receiving or is on a very slow link. The solution emulates
what ReverseTcpDouble already does, which is stage each connection
in a new thread. However, given that a high number of threads
can be a problem on some operating systems (*ahem* win32) this
option is not enabled by default.
We should look into thread pooling and handle_connection() timeouts
as well as event-based polling of multiple clients as alternatives,
but this option will improve the situation for our existing users.
Even though there are calls to has_read_data(), it doesn't prevent
the put() call from blocking in a dead client or slowaris-like
situation. By moving the inp/out detection into the thread, we
allow the main handler to keep processing connections even if
a single connection hangs.
* Fix a bug in LoginScanner::SSHKey (which was copy-pasted from SSH)
where the ssh_socket accessor was not being set because of a
shadowing local var
* Fix a bug in the db command dispatcher where an extra column was
added to the table, causing an unhandled exception when running the
creds command
* Add a big, ugly, untested class for imitating
Metasploit::Framework::CredentialCollection for ssh keys. This class
continues the current behavoir of silently ignoring files that are a)
encrypted or b) not private keys.
* Remove unnecessary proof gathering in the module (it's already
handled by the LoginScanner class)
This attempts to change the output of the command as little as possible,
but removes the ability to add and delete for now. At some point, we'll
need to add that back in.

3 database commands in msfconsole check for framework.db.driver to be
set, so driver must be set when the connection is already established by
the Rails initialization.
MSP-9994
Rescue `ActiveRecord::ConnectionNotEstablished` in
`Msf::DBManager#connection_established?` in addition to
`PG::ConnectionBad` to handle when the connection has been removed.
* I verified that changes to PDF mixin do not affect any older modules that
generate PDF. I did this by (on each branch) running in irb, then
running the module and diffing the pdf's generated by each branch. There were
no changes.
* This refactors the logic of webview_addjavascriptinterface into a mixin (android.rb).
* Additionally, some behavior in pdf.rb had to be modified (in backwards-compatible ways).

Extra config and initializers that can we shared between
Metasploit::Framework::Application and the future
Metasploit::Framework::Engine. Move the default encoding setup from
lib/msf/sanity.rb to a before_initialize callback for the shared config
so that gems, like gherkin that depend on the utf-8 default internal
encoding can be loaded.
MSP-9653
Calling `ActiveRecord::Base.establish_connection`, followed by
`ActiveRecord::Base.connected?` returns false unless some other code
requires a connection to be checked out first. The correct way to check
if the spec passed to `ActiveRecord::Base.establish_connection` is to
checkout a connection and then ask if it is active.
`Msf::DBManager#connection_established?` does the checkout, active check
and checkin, and should be used in place of
`ActiveRecord::Base.connected?` and
`ActiveRecord::Base.connection_pool.connected?`.
`Msf::DBManager#active` should still be used as it also checks for
adapter/driver usability and that migrations have run.
MSP-9653
Allow rails engines (and other applications, like
Metasploit::Pro::Engine::Application) to define their own module paths
using the paths['modules'] entry for Rails Applications/Engines.
refactor the Hashdump post module for window
to use the new cred creation methods.
Also some extra methods to do db safe checks
for record ids that we need
MSP-9653
If ActiveRecord::Base is already connected, then don't attempt to create
the database (as it involves establishing a new connection) or
establishing a new connection after the creation. Still run the
migrations as the normal Rails::Application.initialize! will result in
ActiveRecord::Base.connected? being true even if migrations are missing.
To be clear, the shell that was tested with was 'windows/shell_reverse_tcp' delivered via 'exploit/windows/smb/psexec'
Additional changes required to fix regex to support the multiline output. Also, InstanceId uses a lower case 'D' on the platforms I tested - PowerShell 2.0 on Windows 2003, Windows 7, Windows 2008 R2 as well as PowerShell 4.0 on Windows 2012 R2.
This method doesn't appear to be used anywhere in the Metasploit codebase currently.
I have a case where on a Windows 2008 R2 host with PowerShell 2.0 the 'have_powershell' method times out. When I interactively run the command I find that the output stops after the PowerShell command and the token from 'cmd_exec' is NOT displayed. When I hit return the shell then processes the '&echo <randomstring>' and generates the token that 'cmd_exec' was looking for. I tried various versions of the PowerShell command string such as 'Get-Host;Exit(0)', '$PSVErsionTable.PSVersion', and '-Command Get-Host' but was unable to change the behavior. I found that adding 'echo. | ' simulated pressing enter and did not disrupt the results on this host or on another host where the 'have_powershell' method functioned as expected.
There may be a better solution, but this was the only one that I could find.
