The call to `getenv` failed when `%` or `$` were used because of the
differences between Meterpreter handling and MSF handling.
Meterpreter effectively ignores (ie. strips out) the platform-specific
characters which are used for environment variables. In the `getenv`
call, MSF was invoking `getenvs` and getting a full hash of values, then
attempting to index into the hash using a string which may be "polluted"
with those platform-specific characters. This meant that there was a
discrepency between what was returned and what was used to index and
as a result, the value would come out as `nil`.
For example, calling `getenv('%FOO%')` would result in a hash with
`{'FOO'=>'bar'}`, so looking for '%FOO%' in this result would yield
nothing.
This commit changes this so that the name is ignored and the first
value is returned.
It's sad nobody is actually using it. See article: "Across desktop and
mobile, Chrome is used more than Firefox, IE, and Opera combined" -

Older versions of OpenSSL did not export the OP_NO_COMPRESSION constant,
so users running metasploit on systems with old copies of openssl
would throw a NameError since the constant did not exist.
[SeeRM #823], where Stephen was asking for SSL compression for
Meterpreter -- this isn't that, but it's at least now possible for other
Metasploit functionality.
Added targets for 8 specific targets that I've tested: Cisco WAP4410N,
Honeywell WAP-PL2 IP Camera, Netgear DG834, Netgear DG834G, Netgear
DG834PN, Netgear DGN1000, Netgear DSG835, Netgear WPNT834
Added functionality to the CmdStagerEcho mix-in to support encoding via
octal instead of hex based on the :enc_type option. This is because many
devices would not output hex encoded values properly.
Added options on a per-target basis for the PackFormat (endian pack()
values for communication), UploadPath (because /tmp wasn't always
writable), and PayloadEncode (previously mentioned octal encoding
option)
Note for some reason, some devices communicate over one endianness, but
then require a payload for the other endianess. I'm not sure what's
causing this, but if those specific combinations are not used, the
exploit fails. More research may be required for this.
This is a separate extension because the new version doesn't support
as many operating systems as the old version, but it does have more
new features which are really funky.
Migrated the Sercomm module to use the CmdStager mixin to provide
uploading of the ELF binary.
Modified the CmdStagerEcho mixin to allow bypass of the "-en " since in
this case, the device messed up when it was used, and would actually
write the "-en " to the file, from some flaky busybox version of "echo".
The getenv call in sys/config was renamed to getenvs and now uses
the splat operator so that arrays don't have to be passed in. A
new function called getenv was added which takes a single argument
and returns a single value back (for ease of use).
[SeeRM #8729] - This meterpreter command allows the attacker to observe the target at real-time
by turning their webcam live. There is also a HTML-based player provided, which does not require
a plugin or anything, just open it with a browser. The HTML-based player also allows the attacker
to put livestream on the web (evil? yeah, kind of.)
The only conflict was the regex option for no encoding, which was added
after @Meatballs1's original PR for rapid7/metasploit-framework#1421
Also fixes the module with the new license splat.

No more late night and rushed commits, its still and wastes people's time.
Thanks sinn3r for getting on this. Apologies for the poor quality of the PR.
HTTP(s) payloads don't exit cleanly at the moment. This is an issue that's
being addressed through other work. However, there's a need to be able to
terminate the current HTTP(s) session forcably.
This commit add a -s option to kill, which (when specified) will kill
the current session.
This command will allow the attacker to grab environment variables from the
target, if they exist. Calling this function allows for one or more values
to be passed in, which should match the name of the variable required. If
the variable is found, it is returned. If it is not found, the variable
is not returned (ie. it's not present in the resulting hash).
Note 1: POSIX environment vars are case-senstive, whereas Windows is not.
Note 2: POSIX doesn't seem to cough up user environment vars, it only returns
system vars. I'm not sure why this is, but it could be because of the way
we do linking on POSIX.
Also disables the compression by default. TLS-level compression is almost
never used by browsers, and openssl seems to be the only one that enables
it by default.
This also kills some ruby < 1.9.3 code.
This version modifies the existing meterpreter session and bumps the privs
up to SYSTEM. However it's not how local exploits are supposed to work.
More work will be done to make this create a new session with the elevated
privs instead.
Updated the comments and indentation so they're not blatantly wrong.
Adjusted the pxexploit module so that it doesn't break any more as
a result of the refactoring.
The lanattacks module didn't seem to have a command dispatcher, and
hence loading the module would always result in a failure. This
commit fixes this problem.
The commit contains a bit of a refactor of the lanattacks code to be
a little more modular. It also has a shiny new dispatcher which breaks
the DHCP and TFTP functionality up into separate areas.
* Rename methods to remove redundancy.
* Update bins to freshly compiled version.
* Use the Rex Table functionality instead of custom look.
* Use the `usage` feature of the Arguments class for help.
In some cases the password value that comes out of mimikatz results
is `nil`, instead of an empty string. This fixes this so that if
the string is `nil` is falls back to an empty string, resulting in
the call to `gsub` working instead of failing.
In certain scenarios on Windows XP there are times when creating a
shell fails with the error `ERROR_PRIVILEGE_NOT_HELD`. When this
happens the user will usuall fallback to a non-impersonated shell
via the command: `execute -f cmd.exe -H -i -c`
This patch catches the error, warns the use of the failure and then retries
to create the interactive shell without the `-t` flag.
Image data copied to the clipboard, such as a screenshot, is converted to a JPEG using GDI+, and downloaded to the local loot folder.
This feature doesn't work with W2K as a result, but that doesn't really bother me. The code is simpler and much smaller as a result and doesn't require the inclusion of the jpeg library code.
