triggered for the tls change cipherspec message.
Also - fix small bug. In case SSL::disable_analyzer_after_detection was set
to F, the ssl_established event would fire after each data packet after the
session is established.
This also fixes the heartbleed detector to work for encrypted attacks in this
branch again. It stopped working, because the SSL analyzer now successfully detects
established connections, and the scripts usually disable analyzing after that.
(The heartbeat branch should not have been affected)
That means that, for example, connections that are terminated with an alert during the
handshake never appear in the ssl.log.
This patch changes this behavior - now all ssl connections that fire any event are logged.
The protocol confirmation of the ssl analyzer is moved to the client_hello instead to
the server hello. Furthermore, an additional field is added to ssl.log, which indicates
if a connection has been established or not (which probably indicates a handshake problem).
The event now really returns the extension. If openssl supports printing
it, it is converted into the openssl ascii output.
The output does not always look pretty because it can contain newlines.
New event syntax:
event x509_extension(c: connection, is_orig: bool, cert:X509, extension: X509_extension_info)
Example output for extension:
[name=X509v3 Extended Key Usage,
short_name=extendedKeyUsage,
oid=2.5.29.37,
critical=F,
value=TLS Web Server Authentication, TLS Web Client Authentication]
[name=X509v3 Certificate Policies,
short_name=certificatePolicies,
oid=2.5.29.32,
critical=F,
value=Policy: 1.3.6.1.4.1.6449.1.2.1.3.4^J CPS: https://secure.comodo.com/CPS^J]
- Thanks for help from Rafal Lesniak in nailing down the location
of the bug and supplying test traffic.
- Test traffic with a TLS 1.2 connection.
- Addresses ticket #1020
- SSL related files and classes renamed to remove the "binpac" term.
- A small fix for DPD scripts to make the DPD log more helpful if
there are multiple continued failures. Also, fixed the SSL
analyzer to make it stop doing repeated violation messages for
some handshake failures.
- Added a $issuer_subject to the SSL log.
- Created a basic test for SSL.
