[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.
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!.
Msf::Config.install_root already existed, but I didn't know about it
until egypt pointed it out, so remove the new Msf.root and use
Msf::Config.install_root in the specs instead.
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.
