In that order. #1476 was an attempt to salvage the functionality, but
sinn3r found some more bugs. So, undoing that, and undoing #1444 as
well.
First, do no harm. It's obvious we cannot be making sweeping changes in
libraries like this without a minimum of testing available. #1478 starts
to address that, by the way.
FixRM #7752
These modules require the target URI to be a directory path. So
if you remove the trailing slash, the web server might return a
301 or 404 instead of 200.

Merge remote-tracking branch 'ChrisJohnRiley/set_normalize_uri_on_modules'
into set_normalize_uri_on_modules
Note that this trips all kinds of msftidy warnings, but that's for another
day.

* Adds Exploit::EXE to windows/postgres/postgres_payload. This gives us
the ability to use generate_payload_dll() which generates a generic dll
that spawns rundll32 and runs the shellcode in that process. This is
basically what the linux version accomplishes by compiling the .so on
the fly. On major advantage of this is that the resulting DLL will
work on pretty much any version of postgres
* Adds Exploit::FileDropper to windows version as well. This gives us
the ability to delete the dll via the resulting session, which works
because the template dll contains code to shove the shellcode into a
new rundll32 process and exit, thus leaving the file closed after
Postgres calls FreeLibrary.
* Adds pre-auth fingerprints for 9.1.5 and 9.1.6 on Ubuntu and 9.2.1 on
Windows
* Adds a check method to both Windows and Linux versions that simply
makes sure that the given credentials work against the target service.
* Replaces the version-specific lo_create method with a generic
technique that works on both 9.x and 8.x
* Fixes a bug when targeting 9.x; "language C" in the UDF creation query
gets downcased and subsequently causes postgres to error out before
opening the DLL
* Cleans up lots of rdoc in Exploit::Postgres
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.
Since the payload is now run in the .so constructor, there's no need to
be compatible with a particular Postgres API.
Also:
- report the service
- delete the payload in the payload itself to reduce forensics
footprint
- randomize the created function name instead of abusing
postgres_create_sys_exec
