[Fixes#38426061, #38097411]
Msf::Modules::Loader::Directory#read_module_content may calculate a non-existent
module_path that gets passed to File.open causing an Errno::ENOENT exception
to be raised when using the module cache with a module that has been
moved to a new path (as is the case that originally found this bug) or
deleted. Now, the exception is rescued and read_module_content returns
an empty string (''), which load_module detects with
module_content.empty? and returns earlier without attempting to module
eval the (empty) content.
As having Msf::Modules::Loader::Directory#read_module_content rescue the
exception, meant there was another place that needed to log and error
and store an error in Msf::ModuleManager#module_load_error_by_path, I
refactored the error reporting to call
Msf::Modules::Loader::Base#load_error, which handles writing to the log
and setting the Hash, so the error reporting is consistent across the
loaders.
The exception hierarchy was also refactored so that
namespace_module.metasploit_class now has an error raising counter-part:
namespace_module.metasploit_class! that can be used with
Msf::Modules::Loader::Base#load_error as it requires an exception, and
not just a string so the exception class, message, and backtrace can be
logged.
* Pulls common code up from several methods into #open_sc_manager
* Deprecates the name Windows::WindowsServices in favor of
Windows::Services. The platform is already clear from the namespace.
* Makes the post/test/services test module actually work

Msf::Modules::Loader::Archive#each_module_reference_name tried to check
the enabled types for the module_manager by accessing the
enabledment_by_type Hash, which is protected. Instead, it should use
the public type_enabled? method.
Add specs to test all of Msf::Modules::Loader::Archive while testing
each_module_reference_name. In order to properly test that modules
could be found in archives, I had to produce a fastlib archive, so there
is now a spec for FastLib.dump and FastLib.load. Some specs are marked
pending as I found a bug in FastLib, which has a work-around. The bug
is filed in PivotalTracker as
https://www.pivotaltracker.com/story/show/38730815 and the pending tests
include the URL also in their tags.
Just had a brain fart when converting the hash key names and translated
:mtype to :modification_time instead of the correct :type. Correct key
names are in
Msf::ModuleManager::Cache#module_info_by_path_from_database!.
Depending on how a socket was created, #getsockname will return either a
struct sockaddr as a String (the default ruby Socket behavior) or an
Array (the extend'd Rex::Socket::Tcp behavior). Avoid the ambiguity when
generating SSL certificates for meterpreter handlers by always picking a
random hostname.
This is by no means a proper fix for the underlying problem of
Socket#getsockname having ambiguous behavior before and after being
extended with Rex::Socket::Tcp. It does, however, solve the immediate
problem of not being able to create tunneled meterpreter sessions over
http(s) sessions.

[Fixes#37630057]
Modules were always being detected as having file changes because the
parent_path directory, instead of the actual module_path, was being
passed to module_manager.file_changed?, which caused the modification
times to not match.
To ensure this change fixes the ambiguous module warnings, a full spec
for Msf::Core::Modules::Loader::Base has been written.
spec/msf has moved to spec/lib/msf to match conventional spec layout and
allow for the spec/support directory to not be confused as a lib
subdirectory being tested.
Also adds some clarifying commentation and adds todb to the list of
authors since he wrote the original module for windows upon which this
one is based.
Ensures that the absence of activerecord does not prevent msfconsole
from loading. This returns us to the previous state of affairs where it
is possible to use the framework entirely without a database.
To test:
1. rm -rf lib/gemcache/ruby/1.9.1/gems/activerecord*
2. remove any locally installed versions of activerecord
3. msfconsole
msfconsole should load up with a warning like so:
[-] ***
[-] * WARNING: No database support: LoadError cannot load such file -- active_record
[-] ***
... and should still be functional.
I missed a spot where I referenced the nested_paths as nested_pathnams
after I renamed the variable. Now, Msf::ModuleManager#add_module_paths
has rspec tests.
Rspec can be invoked with `rake` as the default task or `rake spec`
explicitly.
I changed RuntimeError to ArgumentError since that error was more
specific to having a bad argument error. I adding missing dependencies
to the Gemfile and a require to msf/core/db_manager.rb where it errored
out trying to access Msf::Config when I just did require 'msf/core' in
the spec.

The merging of reload_module and the various load_module methods
resulted in the module loading from disk, but because the Hash entry in
the module manager was not deleted before on_module_load was called, the
newly reloaded module was logged as an ambiguous module name instead of
a reload. In order to report the reload errors correctly, I determined
that module_load_error_by_reference_name should really be
module_load_error_by_path. I eliminated faild in favor of this new name
since failed was just calling the attribute and the attribute's name is
clearer about the format of the data.
Tested by run rexploit and then exiting over and over with
ms08_067_netapi. When I messed up the file so it couldn't load, by
adding `inclde Exploit` (note mispelling of `include`), it reported the
error to msfconsole. When I removed the bad line and added a puts
"RELOADING <n>", where I kept incrementing n and saving the file, the
new number appeared during each rexploit.
[#36737359]
Write the module_eval backtrace to the log, but only the error's class
and name to Msf::ModuleManager#module_load_error_by_reference_name as
the contents of the Hash are printed in the console, which should never
recieve backtraces.
[#36737359]
Refactor the behavior of loading symbolic modules from cache by renaming
methods so it's clearer what they do and ensure that cached modules from
Fastlibs and directories can both be loaded, which was not previously
possible since the demand_load_module only called load_module_from_file.
[#36737359]
On Linux, some of the unqualified constants that resolve on Mac OS X,
don't resolve, so to prevent errors (and because I can't justify why the
unqualified constants should resolve on OS X), I'm qualifying all the
Msf constants that are referenced in the code I've refactored.
[#36737359]
Fix the YARD docs to document the return values and make them consistent
with the modules being called. Ensure the force flag is passed as an
option to load_modules instead of a positional argument.
[#36737359]
When starting msfconsole, 'bundler/setup' is not required, the
'msf/env/gemcache' is required instead. Unlike 'bundler/setup' the
msf/env gemcache does not do the automatic requires for gems in the
cache, so explicit requires on 'active_support/concern' is needed to get
ActiveSupport::Concern defined. (I could have done require
'active_support' to match the behavior of 'bundler/setup', but a smaller
require seemed more appropriate.
removes unnecessary parens (and yes I confirmed they are properly
paired), and adds some comments regarding this as not being an ideal
solution, but rather a stopgap
Changed lexical scope when I changed the declaration from module Msf;
class ModuleSet to class Msf::ModuleSet so that constants in Msf would
not automatically resolve.
I wasn't using any the features of ActiveSupport::Concern in
Msf::ModuleManager::Reloading, so remove the extend and just include it
as a regular module.
Came up on IRC, I'm not attached to it, but this commit adds the
rename_file method to lib/msf/core/post/file.rb and aliases it to
move_file and mv_file
[Fixes#36737359]
Refactor Msf::ModuleManager into concerns so its easier to understand and
duplicate code can be made DRY. The refactoring also ensures that when
loading from directories, Fastlibs, or reloading, the wrapper module will
always be named so that activesupport/dependencies will function.
[#36737359]
active_support/dependencies cannot resolve missing constants in Metasploit
modules because the wrapper module is anonymous. In order to make the
wrapper module non-anonymous, the module must be assigned to a constant.
Since we don't want modules colliding, the wrapper module needs a unique
name, so use the module lookup name to derive the proper nested module names
to namespace the wrapper module. All derived modules are nested under
Msf::Modules. The name derivation handles invalid characters for constant
names such as digits as the first character or non-alphanumeric character.
The invalid constant name characters are converted to their hex value and
prefixed with X, so '-' in a name become 'X2d'.
The 'unless' statement expects there's always a value for USERNAME
and PASSWORD. We might as well just set '' as the default value
to avoid the NoMethodError mistake. Related to bug #7140.
Also gets rid of the conn_ids array, which was never pruned (and
without some extra gymnastics in meterpreter/client.rb *can't* be) when
handler URLs were removed.
Unfortunately, adds a dep on bionic for runtime compilation.
Gets ring0, sets the (res)uid to 0 and jumps to the payload. Still some
payload issues because linux stagers don't mprotect(2) the buffer they
read(2) into. Single payloads work fine, though.
Also cleans up and improves local exploits' ability to compile C.
[SEERM #3038]
When using the reload_all command, the framework will trigger an
'undefined method module_history' error, because we're missing
an accessor.
Also, even though reload_modules returns "counts". That actually
returns a hash instead of a real count of modules... the return
value is also never actually used anywhere. But to make this
part not broken, we return the actual count.
This is a fix for issues related to:
'undefined method `[]' for nil:NilClass'
It is possible that a PDF may not have the 'Size' xref, and people
are running into the 'undefined method'[]' for NilClass' exception.
Because the pdf parser always assumes there is a Size field,
so it uses a match() function to find the value for Size, which
can be nil.
See the following bug report for example:
https://dev.metasploit.com/redmine/issues/7014
Something is still broken, my socket() is returning EAFNOSUPPORT whereas
what looks like the same syscall in wunderbar_emporium's exploit.c is
returning a socket. Similarly, my __mmap2() is returning EFAULT when
trying to map anything, not just NULL.
This can currently build an executable that creates a socket, opens a
temporary file, truncates that file with ftruncate(2) and calls
sendfile. Still needs to mmap NULL and figure out ring0 shellcode.
Baby steps.
