If a severity level >= INFO was supplied,JSON* and CSV output were
not writing error conditions in fileout(). As those indicate a problem
of the assessment, this has been fixed so that if any severity is
supplied to testssl.sh it will always write WARN conditions
to file when detected.
Also if the scan was interrupted on the client side where previously
a scanTime of 0 was written to the log file now it will raise a warning
that the scan was interrupted.
See also #769. Error conditions after starting a scan on the server side
(TCP Reset, DROP after a while) still won't be treated accurately in the file output
with an error message but the resulting JSON should be still valid.
This prime appears to be not only in HAProxy 1.5 but as well in the newer versions. The test result will return incorrect response message, when testing on the newer HAProxy versions (ie. 1.5 is detected but 1.8 is installed).
OpenBSD doesn't seem to be able to convert from $(date)
output to a more readable format as performed on notBefore
and notAfter from x509(1). Thus an exemption is made and
just display the format like x509(1) shows.
Also newer OpenBSD come with a newer LibreSSL version,
thus the pattern when to display a warning when the
"too unreliable to determine trust" warning is displayed.
This commit adds support for TLSv1.3 draft 24. The only change between draft 23 and draft 24 is that draft 24 requires the version number of the record layer to be "0303" for a second ClientHello, whereas draft 23 allowed the version number for both the initial and second ClientHello to be "0301".
The current text reads:
legacy_record_version This value MUST be set to 0x0303 for all
records generated by a TLS 1.3 implementation other than an
initial ClientHello (i.e., one not generated after a
HelloRetryRequest), where it MAY also be 0x0301 for compatibility
purposes.
If extra extensions are provided to socksend_tls_clienthello(), the socksend_tls_clienthello() needs to determine what extensions were provided so that it doesn't add any of these extensions a second time. The code that was looping through the extra extensions to get the extension IDs was using the value for the length of the string. This commit fixes the error.
As per @krissi's suggestion this is a smart addition to add privat CAs
to all certificate stores -- during runtime only. The switch --add-ca or
--add-CA expects an argument of one additional CA file or a comma separated
lists of them. The enviroment file ADDITIONAL_CA_FILES can be used
alternatively.
This fixes eventually #230.
For recognising error conditions during run any testssl.sh run, the program
returns 0 if all checks have been performed successfully and unambiguously. 1
is returned per error or unambiguous condition and per IP. E.g. ./testssl.sh
--ssl-native testssl.net with two IP addresses returns 2 as each client
simulation gets a "1" (ssl-native returns currently wrong results here).
This fixes#986.
A kind of vulnerability scoring for monitoring tools or CI will be done
later separately, see #985 and #327.
As before (see #971) and as indicated (#970) some minor
changed to the jsonID have been taking place. Some
redundant verbosity has been eliminated, some IDs
changed the name.
For HTTP2 you should now ALPN_HTTP2.
Some obvious CWEs were added in the JSON section.
ke for null cipher list, information leakage in
the http headers. There's probably space for improvements.
A few early time marks were added to debug time spend.
Some servers will respond with an alert to a ClientHello that does not indicate support for secure renegotiation, which may be signaled through either an extension or the 0x00,0xff "cipher suite." In some cases testssl.sh calls tls_sockets() without including "00,ff" in the list of cipher suites, which results in some servers rejecting a ClientHello that would otherwise result in a successful connection.
This PR fixes the problem by adding "00,ff" to any ClientHello where it was previously missing, with one exception. If a TLSv1.3 ClientHello is being sent and only TLSv1.3 ciphers are listed, then the "00,ff" cipher suite is not added.
Error codes now done until run_server_defaults(). Previous
sections modified so that execution errors are added.
Modified in compare_server_name_to_cert() ret --> subret.
From the code perspective a clear distinction between
passing an error code and a functional return code
would be great. Still has to be determined whether it
maybe better to rename ret into something different.
Removed a stale code line in run_server_preference() for STARTTLS.
Following the recommendation from @dcooper16 this commit is addressing
a situation when the scan couldn't finish for external reasons and as
a consequence left a non-valid JSON file behind.
It also starts addressing #986 so that the protcol section only returns
a non-zero value if a check coundn't be performed or gave results which
weren't clear.
It also fixes a typo where in the TLS 1.3 check a status from the TLS 1.2
check was not correctly interpreted (TLS 1.2 not offered).
This commit fixes#983 by ensuring that the line printed just before calling "return" prints a newline character. It also fixes the problem that no output is sent to the JSON/CSV file in some cases in which no fallback is possible since the server does not support two different protocols below TLSv1.3.
In order to be more consistent with the other output functions having
"svrty" in their name, *_done_best and *_done_good were changed to
*_svrty_best and *_svrty_good.
run_spdy/run_http2 were renamed to run_npn and run_alpn as this is
what is actually being tested. Also the terminal and file output
is now reflecting this.
Also #980 was fixed in a sense that (only) for ALPN the protocol
h2 will get a "good". There will be an additional CSV/JSON line
for this.
This commit fixes#981 by using a while loop instead of a for loop to check each DNS name in the SAN extension, copying the syntax used in certificate_info() to display all of the SANs.
This commit adds code to run_server_defaults() so that in debug mode all of the server's certificates are saved in $TMPDIR in both PEM-encoded format and pretty-print text format.
testssl.sh was recently changed to store the text printout of the host's certificate in a file, $HOSTCERT_TXT, and then use this file in some places rather than calling "$OPENSSL x509 -in $HOSTCERT -text -noout". There was a problem, however, in cases in which the server had more than one certificate (including cases in which the server returned an unrelated certificate when sent a ClientHello w/o SNI), since the contents of $HOSTCERT_TXT was not always being updated whenever $HOSTCERT changed.
This commit fixes that problem by replacing the previous solution with a less ambitious one. In this version, the global variable is eliminated and instead run_server_defaults() stores a text version of each certificate it finds in an array. This value is then passed to certificate_transparency() and certificate_info() for use. It is also passed from certificate_info() to must_staple().
determine_trust() uses the output of "$OPENSSL verify" to determine whether OpenSSL can construct a valid certification path for the server's certificate. If it does not find a string of the form "error [1-9][0-9]? at [0-9]+ depth lookup:" in the output, then it assumes that validation was successful. In current versions of OpenSSL, when this error is created it is printed to stdout, but in OpenSSL 1.1.1 is it printed to stderr. Since testssl.sh only checks the output sent to stdout, it incorrectly treats all certificates as valid if OpenSSL 1.1.1 is used.
This commit fixes the problem by checking the text that is sent to both stdout and stderr.
This commit also fixes a typo in the call to "$OPENSSL verify" which resulted in the environment variables SSL_CERT_DIR and SSL_CERT_FILE not being set to "/dev/null".
In ``must_staple()`` and ``certificate_info()`` were the jsonIDs
changed to OpenSSLi / IETF names so that testssl.sh is more compliant
to the rest of the world. There might be still space for improvements
are far as common naming scheme is concerned.
The host certificate is now being delivered in JSON and CSV. For
further usage " " needs to be converted back to linefeeds.
Certificate Expiration was renamed to Certificate Validity.
The order of outputting the certificate serial and SHA1 fingerprint
has been swapped.
Also ``certificate_info()`` makes more use of HOSTCERT_TXT.
