If a host is blacklisted, we won't create the service for it. If we
don't create the service, we don't want to create entries for the web
pages.

someone tried to fix a rails deprecation warning by doing an
eager load, but caused an actual exception instead. switching to
propper joins makes everything work properly
MS-1593
The exception handling in the #exploit_simple method tries to set
error on exploit but exploit is defined within the begin block
causing a noMethodError on nilClass
MS-1608
When a module uses the HttpClient mixin but registers the USERNAME
and PASSWORD datastore options in order to perform a form auth,
it ruins the ability to also perform a basic auth (sometimes it's
possible to see both). To avoid option naming conflicts, basic auth
options are now HTTPUSERNAME and HTTPPASSWORD.
Fix#4885
Using the ruby methods for generating assembly blocks defined or
separated in prior commits, create a new payload from the existing
assembly blocks which performs a DNS lookup of the LHOST prior to
establishing a corresponding socket and downloading, and
decrypting the RC4 encrypted payload.
For anyone looking to learn how to build these payloads, these
three commits should provide a healthy primer. Small changes to
the payload structure can yield entropy enough to avoid signature
based detection by in-line or out-of-band static defenses. This
payload was completed in the time between this commit and the last.
Testing:
Win2k8r2
ToDo:
Update payload sizes when this branch is "complete"
Ensure UUIDs and adjacent black magic all work properly
Using the separation of block_recv and reverse_tcp, implement
reverse_tcp_dns using original shellcode as template with dynamic
injection of parameters. Concatenate the whole thing in the
generation call chain, and compile the resulting shellcode for
delivery.
Metasploit module pruned to bare minimum, with the LHOST OptString
moved into the library component.
Testing:
Win2k8r2
ToDo:
Update payload sizes when this branch is "complete"
Ensure UUIDs and adjacent black magic all work properly
Misc:
Clean up rc4.rb to use the rc4_keys method when generating a
stage. Makes the implementation far more readable and reduces
redundant code.
Convert reverse_tcp_rc4 and bind_tcp_rc4 from static shellcode
substitution payloads to metasm compiled assembly approach.
Splits up metasm methods for bind_tcp and reverse_tcp into socket
creation and block_recv to allow for reuse of the socket methods
with the RC4 payloads, while substituting the block_recv methods
for those carrying the appropriate decryptor stubs.
Creates a new rc4 module carrying the bulk of the decryptor and
adjacent convenince methods for standard payload generation.
Testing:
Tested against Win2k8r2, Win7x64, and WinXPx86
ToDo:
Ensure all the methods around payload sizing, UUIDs, and other
new functionality, the semantics of which i do not yet fully
understand, are appropriate and do not introduce breakage.
