Some servers like the one from the satire magazine "focus.de"
choose to return gzip encoded body during run_http_haders().
This has led sometimes to misintepretation that an IPv4 address
is present in the header.
This commit fixes that by telling the server not to want a gzipped
response and if still returned grep properly the return.
When testing servers which fall back after succeeding the STARTTLS handshake
to the underlying protocol (smtp, ftp etc.) there was often misleading output
=not available instead of notifying the user that there's a problem.
Now it is being tested in parse*serverhello() functions whether the first
by resembles a 5XX code and STARTTLS is supposed to be tested and then
passes an error code back to the caller , i.e. tls_sockets() and then
run_protocols(). Also other error code after the handshake are passed
better.
This is only an addition to the top level function run_protocols().
We might want to look into other top level functions too
In scenarios where --ssl-native was chosen AND the
openssl binary wasn't supporting the protocol
there were two warnings. This has been addressed.
Also tls_sockets() can return different values -- for now: 6 -- as
tested by the caller in run_protocols. In order to make
it more robust a fixme statement was added so that the
user becomes iat least aware of it.
After changing the logic from $PROTOS_OFFERED
contaning each protocol detected to $PROTOS_OFFERED
contaning each protocol + colon yes or no there
wasn't a change for the sanity check that no protocols
are offered. This fixes it.
This PR adds TLSv1.3 support for the negotiated protocol and cipher in run_server_preference(). This mostly addresses #893, however, run_server_preference() will not work with a TLSv1.3-only server as it will fail when trying to determine whether the server has a cipher order.
Note that with this PR run_server_preference() will not always provide consistent results when testing a server that does not support TLSv1.3 using a version of OpenSSL prior to 1.1.1. If it is determined before running run_server_preference() (using run_protocols()) that the server does not support TLSv1.3, then run_server_preference() will using OpenSSL to determine the negotiated protocol and cipher. However, if it has not yet been determined that the server does not support TLSv1.3, then run_server_preference() will use tls_sockets(), which tries to simulate OpenSSL 1.1.1. Since the list of cipher lists sent will differ the negotiated cipher will sometimes differ. In addition, when a cipher suite that uses an ephemeral ECDH key is selected, the negotiated curve is sometimes different.
This PR fixes#901. When $OPENSSL_TIMEOUT is set and mass testing is being performed, this PR changes find_openssl_binary() so that only child instances modify $OPENSSL to add the call to timeout.
This PR also changes the warning in case $OPENSSL_TIMEOUT is set and the timeout binary cannot be found so that the warning message is printed even if $WARNINGS is "off" or "batch".
There's a new socksend() function which gives up to 8% performance
benefit (LAN) as is saves 3 sed and 1 tr command in every socksend call.
It has not been put in production yet as it shows a problem in ticketbleed
check and it is late and I call it a day ;-) and resolve that later (see #902).
For performance tests it's quite handy to also have in the flat json format
a footer with time consumed for each run. fileout_json_footer() was
patched accordingly.
... from "--" to "not offered". Reason: e.g. on a white
terminal background it is hard to detect that there's
an output. Also "not offered" is more consistent with
the value of protocol checks.
When the server's response to the ClientHello message (i.e., the ServerHello, Certificate, ServerHelloDone) is split across more than one packet, the current call to tls_sockets() in run_heartbleed() only retrieves the first packet. As a result, sometimes when run_heartbleed() believes that it is reading the response to the Heartbleed payload it is actually reading the continuation of the response to the ClientHello message.
This PR fixes the problem by indicating in the call to tls_sockets() that the ephemeral key is needed. This causes tls_sockets() to continue requesting additional packets until it receives the ServerHelloDone.
There was an error in e450eb34e4
which addressed #846 which lead to the problem that an output filename
could start with a "." if no FNAME_PREFiX and if just --html, --csv
or --log or --json* was supplied.
This commit fixes the problem.
When the certificate signature algorithm is RSA-PSS and OpenSSL 1.1.1 is used $cert_sign_algo contains some trailing space characters, which causes the algorithm not to be recognized in the case statement. This PR fixes the problem by removing any trailing space characters from $cert_sign_algo.
This PR fixes a false positive in std_cipherlists(). Currently, sclient_success is not initialized (so it initially set to 0). If a server is being tested that only supports TLSv1.3, the --ssl-native option is not used, and run_protocols() is run before run_std_cipherlists(), then for many of the calls to std_cipherlists() no tests are run and so sclient_success remains at its initial value (0), which is treated as success (i.e., the server supports at least one of the ciphers in the list).
The reason this happens is that in the testing loop, the TLSv1.3 test is skipped if the list of ciphers doesn't include any TLSv1.3 ciphers (and only the "Strong encryption" test includes TLSv1.3 ciphers) and the tests for each of lower versions of SSL/TLS is skipped since it was already determined in run_protocols() that those versions weren't supported.
This PR adds a check for TLSv1.3 support to run_protocols(), checking for support for the final version of TLSv1.3 (0x0304) as well as drafts 18, 19, 20, and 21 (0x7F12, 0x7F13, 0x7F14, and 0x7F15).
File names are now auto-generated by using "-oA auto" / -oa "auto"
--similar to --csv and friends.
Also the formerly hidden switches --outFile and --outfile were added in the
help and in the manual.
Former code implied a determination of the TLS time in
every call of tls_sockets() despite the fact that the
value is only needed at one point in the run.
This removes this behaviour by introducing another global
boolean switch TLS_DIFFTIME_SET which determines whether
the additional cost will be paid or not.
The gain in execution time is a bit meager though. At
most it seems it's 1-3 seconds.
