The only thing that is missing is a signature to detect the protocol (it
has no well-known port).
Reassembly is kind of fidgety - at the moment we only support
re-assembling one simultaneous message per direction (which looking at
our test-traffic might not be a problem). And I am not quite sure if I
got all cases correct...
But - it works :)
This commit mostly does a lot of refactoring of the current SSL
analyzer, which is split into several parts.
The handshake protocol is completely taken out of the SSL analyzer and
was refactored into its own analyzer (called tls-handshake-analyzer).
This will also (finally) make it possible to deal with TLS record
fragmentation.
Apart from that, the parts of the SSL analyzer that are common to DTLS
were split into their own pac files. Both the SSL analyzer and the (very
basic, mostly nonfunctional) DTLS analyzer use their own pac files and
those shared pac files.
All SSL tests still pass after refactoring so I hope I did not break
anything too badly.
At the moment, we have two different modules in one directory and I
guess the way I am doing this might be an abuse of the system. It seems
to work though...
- New fields for certificate type, number of certificates,
if certificates are permanent on the server, and the selected
security protocol.
- Fixed some issues with X.509 certificate handling over RDP
(the event handler wasn't sufficiently constrained).
- Better detection of and transition into encrypted mode. No more
binpac parse failures from the test traces anymore!
- Some event name clean up and new events.
- X.509 Certificate chains are now handled correctly (was only grabbing
a single certificate).
- More data pulled into scriptland.
- Logs expanded with client screen resolution and desired color depth.
- Values in UTF-16 on the wire are converted to UTF-8 before being
sent to scriptland.
- If the RDP turns into SSL records, we now pass data that appears
to be SSL to the PIA analyzer.
- If RDP uses native encryption with X.509 certs we pass those
certs to the files framework and the base scripts pass them forward
to the X.509 analyzer.
- Lots of cleanup and adjustment to fit the documented protocol
a bit better.
- Cleaned up the DPD signatures.
- Moved to flowunit instead of datagram.
- Added tests.
Also changed asynchronous data store query code a bit; trying to make
memory management and handling of corner cases a bit clearer (former
maybe could still be better, but I need to lookup queries by memory
address to associate response cookies to them, and so wrapping pointers
kind of just gets in the way).
- Rename event "socks_login_userpass" to "socks_login_userpass_request"
- Rename event "socks_login_reply" to "socks_login_userpass_reply"
- Split unsupported authN weird into 2 types: method vs. version
Addresses BIT-1011
- This addresses BIT-1011
- Add a new field to socks.log; "password".
- Two new events; socks_login_userpass and socks_login_reply.
- One new weird for unsupported authentication method.
- A new test for authenticated socks traffic.
- Credit to Nicolas Retrain for the initial patch. Thanks!
