When printing a long HTTP security header, this commit causes every row after the first one to be indented by two additional spaces. In the case of very long headers, this extra indentation makes it a little easier for readers to see where the next security header begins.
When printing out HTTP security headers, run_security_headers() uses out_row_aligned_max_width(), since some headers are very long and need to be wrapped. At the moment, however, the first line is too long. The problem is that while "$header $HEADERVALUE" is printed in the indented area, only $HEADERVALUE is passed to out_row_aligned_max_width().
This PR fixes the problem by passing "$header $HEADERVALUE" to out_row_aligned_max_width() so that the the first line is wrapped at the correct place.
testssl.sh hiccups when a user supplied after --json*/--html/-csv
a filename instead of using the corresponding --json*file/--htmlfile/-csvfile
arguments, see #1397.
This PR adresses that in a sense that it tries to detect to following
argument of --json*/--html/-csv. If that matches a suspected filename
it bails out using fatal().
This is not intended to be perfect (when the pattern doesn't match)
but catches the user error in an early stage. See also #1398
Currently sub_cipherlists() and pr_cipher_quality() use different numbers for the same cipher quality ratings. sub_cipherlists() uses:
-2 = pr_svrty_critical, -1= pr_svrty_high, 0 = pr_svrty_low, 1 = pr_svrty_good, 2 = pr_svrty_best
while pr_cipher_quality() uses:
1 = pr_svrty_critical, 2 = pr_svrty_high, 3 = pr_svrty_medium, 4 = pr_svrty_low
5 = neither good nor bad, 6 = pr_svrty_good, 7 = pr_svrty_best
This PR changes sub_cipherlists() (and run_cipherlists()) to use the same numbers for cipher quality as pr_cipher_quality(). It does not change any of the ratings assigned to ciphers by run_cipherlists() or pr_cipher_quality(), so the two are still not in alignment. But, hopefully using the same numbering in both functions will make it a bit easier to compare them and bring them into alignment.
This resolves a regression introduced with IDN support (see also #1370).
* in check_resolver_bins() the determination of HAS_DIG_NOIDNOUT=true was wrong
* in get_*_record() the check for the bool variable was wrong
* in get_*_record() we shouldn't use quotes as they might be expand to a quoted arg
This PR fixes some indentation issues. The PR is a bit long, but it only makes changes to indentation (except for one comment line, where a trailing space character is removed).
This PR fixes#1385.
sub_session_resumption() returns 3 when $CLIENT_AUTH is true. However, the comment at the beginning of the function indicates that 6 will be returned. run_server_defaults() is prepared to handle a return value of 6 (to indicate client auth), but is not expecting 3 as a possible return value.
In cases where the probes for reading memory from the server side were not
successful (=not vulnerable) the TCP connection was not shut down properly --
leading to and undefined state and probably causing problems to a consecutive
check. The server side then assumably from time to time just didn't return
anything which caused a integration test (t/08_isHTML_valid.t) to fail
randomly.
This PR properly terminates the TCP socket connection. Also, as sending the
close notification before closing the socket was duplicated in testssl.sh
that went to a separate function.

This PR enhances support for the latest versions of OpenSSL and LibreSSL.
The development version of OpenSSL at https://github.com/openssl/openssl/ is version 3.0.0-dev. So, checks for OpenSSL versions need to support this version as well. At the same time, the latest versions of LibreSSL are 3.0.0, 3.0.1, and 3.0.2, so version number alone will no longer be sufficient to distinguish between OpenSSL and LibreSSL.
In addition to checks for these new version numbers, this PR addresses a couple of other issues:
- In LibreSSL, the "$OPENSSL ciphers" command will not accept any protocol version other than "-tls1" as a parameter (and even including "-tls1" as an option is described as "deprecated"). So, this PR ensures that "$OPENSSL ciphers" is not passed any protocol version option other than "-tls1" is LibreSSL is being used.
- In OpenSSL 3.0.0-dev, the "$OPENSSL dgst" can no longer be used to compute HMACs, but a new "$OPENSSL mac" function has been created. So, this PR changes hmac() to use "$OPENSSL mac" with OpenSSL 3.0.0-dev.
Note that I have not tested the modified version of sub_session_resumption(). I am just assuming that OpenSSL 3.0.0-dev works the same as OpenSSL 1.1.1 and that all versions of LibreSSL work the same as OpenSSL 1.1.0 and earlier.
When tls_sockets() is used for run_protocols(), for each protocol version the results will indicate whether the server responded to a ClientHello for that protocol version with (1) a ServerHello for that same protocol version, (2) a ServerHello for a different (hopefully lower) protocol version, or (3) a handshake failure.
Currently, however, run_prototest_openssl() does not distinguish between cases in which the server responds with a ServerHello for a different (hopefully lower) protocol version and cases in which the server responds with a handshake failure. This PR changes run_prototest_openssl() so that it distinguishes between these two cases (as long as $OPENSSL supports the protocol version specified in the ServerHello).
Making use of the additional information provided by run_prototest_openssl(), this PR also modifies run_protocols() to check that version negotiation was performed correctly even if $using_sockets is false.
Note that one special case needed to be addressed. If an SSLv3-only server is being tested using an $OPENSSL that does not support SSLv3, then $latest_supported must not be set to SSLv3. In the case of a server like this, it is possible that support for SSLv3 will be determined by determine_optimal_sockets_params(), which will cause run_protocols() to report that the server supports SSLv3, even though $OPENSSL does not support SSLv3 and testing is being performed in --ssl-native mode. If $latest_supported were set, then later tests in run_protocols() would incorrectly report a version negotiation failure, even though the failure to connect was a result of a limitation of $OPENSSL rather than a fault of the server.
When running in debugging mode, HAS_DIG and friends was
still false as check_resolver_bins() was called too late.
This amends basically bac0f66112 .
In cases where a certificate has two CNs, the output contained
a linefeed. This replaces the line feed by a space.
This fixes a bug e.g. when supplying a proxy by a DNS name, testssl couldn't resolve the name as the HAS_ variables initialized by ``check_resolver_bins()`` was done later than ``check_proxy()``.
The patch just puts ``check_resolver_bins()`` earlier in "main"
run_prototest_openssl() currently calls "$OPENSSL s_client" twice, once with $PROXY and once without. The problem is that the results of the first call are just ignored. This commit changes run_prototest_openssl() so that the attempt without $PROXY is only tried if the first attempt was unsuccessful.
If --ssl-native is being used and the server supports SSLv2, but does not support any SSLv2 ciphers, there is a missing line break after the warning message is printed.
run_prototest_openssl() currently checks only stdout for the string "no cipher list", which is an indication that the server supports SSLv2, but no ciphers for that protocol. However, the output that includes "no cipher list" is sent to stderr.
This PR fixes a minor problem with run_protocols() in "--ssl-native" mode if $OPENSSL does not support TLS 1.3. Currently, the warning message that $OPENSSL does not support a protocol is printed when run_prototest_openssl() is called. This causes a problem for the output if $OPENSSL does not support TLS 1.3, since the run_prototest_openssl() is called before the results for TLS 1.2 are printed. The result is something like this:
SSLv2 not offered (OK)
SSLv3 not offered (OK)
TLS 1 offered (deprecated)
TLS 1.1 offered (deprecated)
Local problem: /home/cooper/Desktop/testssl.sh/bin/openssl.Linux.x86_64 doesn't support "s_client -tls1_3"
TLS 1.2 offered (OK)
TLS 1.3 NPN/SPDY not offered
ALPN/HTTP2 http/1.1 (offered)
