This PR adds support for TLSv1.3 to run_std_cipherlists().
This PR also provides a partial fix for #660 - addressing the issue only for run_std_cipherlists(). Rather than testing the server once for each cipher list, it tries the server once for each protocol supported by the server. This makes the testing more robust, but adds significantly to the time it takes to perform the tests.
This PR addresses issue #660 for run_sweet32(), detecting if 3DES is used, even if it isn't used with the highest protocol version supported by the server. As with PR #854, this increased robustness comes at the expense of taking addition time to run the test.
In client_simulation_sockets() and tls_sockets(), don't work to create a SOCK_REPLY_FILE that contains the entire server's response (in cases where the response was spread across multiple packets) unless $DEBUG is at least 1.
I believe there is a typo in the second definition of DEBUG_ALLINONE. If I run testssl.sh using the -x option for bash I get the following error:
testssl.sh: line 12714: -false: command not found
In order to santize input better there's a fucntion
now which does the work . ``safe_echo()``.
It is actually the same as ``tml_out()`` but is a bit snappier.
This PR adds initial support for TLSv1.3 to tls_sockets() and for run_client_simulation(). It does not change any of the other functions test TLSv1.3. So, with the exception of run_client_simulation(), the functionality added by this PR can only be tested using the --devel option.
This PR does not include the ability to decrypt the encrypted portions of the server's response. So, it does not support functions that need to see such things as the server's certificate, status information, or extensions (other than key share).
This PR fixes the use of has_server_protocol() in two places.
Currently std_ciphersuites() only tries SSLv2 if the server is known to support SSLv2. This changes it to try SSLv2 unless the server is known to not support SSLv2.
In run_beast(), tests against the server are run to determine support for TLSv1.2, TLSv1.1, TLSv1, and SSLv3 unless the server is known to support that protocol (i.e., even if has_server_protocol() reports that the server does not support the protocol). This changes it so that a test is only performed against the server if has_server_protocol() reports that it doesn't know whether the protocol is supported.
This may not be specific to LibreSSL, but just my local setup. However, when I test using LibreSSL testssl.sh still prints the following message several times:
WARNING: can't open config file: /usr/local/etc/ssl/openssl.cnf
This PR suppresses the error message for several calls to $OPENSSL and so fixes the problem.
The logic is complete now, so that if a protocol has been detected as
supported or not supported it will save a few cycles not to test
this protocol again.
There's probably -- also besides #839 space for improvements. The
advantage of this solution is that ``has_server_protocol()`` also
marks a protocol as tested if the result of the test is negative.
MongoDB listens on port 27017 and will respond to a direct TLS
ClientHello without the need for STARTTLS. Thus, testssl.sh already
mostly works to scan a MongoDB server.
The problem is that MongoDB will also reply to an HTTP GET request with
a mocked up HTTP response, which was tricking the tool into believing it
was dealing with an HTTP server. The response looks like this:
---
HTTP/1.0 200 OK
Connection: close
Content-Type: text/plain
Content-Length: 84
It looks like you are trying to access MongoDB over HTTP on the native
driver port.
---
Thus, the detection algorith must first look for HTTP, then dig deeper
into the body looking for "MongoDB".
The tool output now says:
Service detected: MongoDB, thus skipping HTTP specific checks
As dcooper16 noted in #834 there are checks which test for openssl versions
but don't take LibreSSL in account. This adds checks to it for several
LibreSSL versions (>=2.1.x) which are known to support ``determine_trust()``
and it HAS_DH_BITS.
Moreover engine check has been improved. Older LibreSSL versions (2.1 specifically)
had different error messages, so the previous checks failed. There's also
a CMD_LINE flag now where one can switch the engine support off: NO_ENGINE .
run_renogo from #834 is still an open issue.
All three issues fixed. Terminal code were actually
tow problems: Logging in from Linux with a 256 color xterm
makes tput set AF from OpenBSD hiccup. And the detection
of not-ncurses style underline e.g. was not working under OpenBSD.
The engine fix was done by David Cooper (see #831).
There's also a name of the binary now (OpenSSL/LibreSSL) for tracking
the flavor used.
SWURL contained for historical reasons trailing blanks
for released versions.
This caused an error in pr_boldurl --> html_out which
didn't write the trailing style info and didn't close
the href tag (travis complained.)
This patch removes the trailing blank but it doesn't
fix the error.
This is an initial implementation of the idea I proposed in #791. It includes checks based on draft-ietf-tls-grease as well as checks for specific implementation bugs that have previously been encountered.
This code needs testing. While I know of one server that will fail if the ClientHello contains more than 128 ciphers, I haven't been able to test any of the other code against any servers that have the tested-for bugs.
In addition, there is a need for polishing. The tests are referred to as `--grease`, which may not be a very user-friendly name. In addition, there is no output providing information about what tests are being performed. If a server fails a test, then a warning message is printed and is sent to `fileout()`. If the server passes all of the tests, then there is just a single output of "No bugs found."
At the moment, the code is not run by default. Unless `-g` or `--grease` is explicitly included in the command line, the code in this commit is not executed.
Currently the call to `$OPENSSL s_client` to obtain the certificate returned by the server when SNI is not provided is in `certificate_info()`, which means that it is called once for each certificate found the various called to `get_server_certificates()`.
This PR moves the call to `$OPENSSL s_client` to `run_server_defaults()` so that the call is made only once, even if more than one server certificate was found.
In addition, in most cases the certificate returned by the server when SNI is not provided will already have been retrieved by `run_server_defaults()` (in rounds 8-14), in which case `$HOSTCERT.nosni` can just be copied from there rather than making an additional call to `$OPENSSL s_client`.
During protocol check if a sever answered unexpected with
closing the conenction or another malformed reply the
output was not ok as DETECTED_TLS_VERSION was empty.
This fixes it by filling the variable with a string in ``parse_tls_serverhello()``
and then check in higher level (``run_protocols()``) the content.
Also it seems that I forgot in the commit from yesterday one ``&&`` to
commit in ``run_breach()``
