It is now being tested whether the binary locale exists and
there's a global introduced for that.
Also there's no fileout warning at this early stage anymore
as it leads to non-valid JSON.
This fixes#2103 in 3.1dev.
Therefore a new global function was declared checking whether any of
the known locales work on the client without seeting them.
C / POSIX should work as well for LC_COLLATE.
This fixes#2100 for 3.1dev.
This PR addresses a bug where a user encountered the question "The results
might look ok but they could be nonsense. Really proceed".
That happened under Darwin and probably some LibreSSL versions when
checking some hosts. sclient_auth() returned 1 indicating no SSL/TLS
handshake could be established.
This PR modifies sclient_auth() so that in those cases 0 is returned by
skipping the check for the session ID. As NO_SSL_SESSIONID needs to
be set when there's no session ID, this is done separately.
* remove hint that LDAP only works with STARTTLS
* Add the relevant LDAP RFC for STARTTLS
* Amend with sieve RFC
* Correct numbering order of RFC section
This commit adds parsing the success value of the STARTTLS upgrade
in LDAP. Only possible values whould be 0 or one according to RFC 2380.
All values not equal to zero will terminate the check.
Also, this PR renames sockread_serverhello() to sockread() as the word
serverhello is pretty misleading. It just reads from ANY socket. (sorry
to confuse people here, that should have gone into a separate PR).
Also sockread() and sockread_fast() are better documented.
See #1258
To do:
* more robustness. At least the success value from the response need to be retrieved and checked via starttls_io().
* double check the pre-handshake before the OID whether it's correct for every case
* documentation
* inline help
It seems to work though against db.debian.org
In run_http_header() the GET command is first sent over TLS using a background process, and then if that does not hang, it is sent again in the foreground. Similarly, service_detection() runs the command in the background.
This commit changes determine_optimal_proto() to follow the example of run_http_header() as protection against the possibility of the HTTP query stalling.
This commit fixes determine_optimal_proto() and run_server_defaults() so that a "Local problem" is reported if a $URL_PATH is specified, the server is TLS 1.3-only, and $OPENSSL does not support -enable_pha (and the server does not offer client authentication as part of the initial TLS handshake).
Checking for client authentication with TLS 1.3 requires post-handshake authentication, which does not appear to be supported by LibreSSL. This commit improves the check for client authentication when testing a TLS 1.3 server using LibreSSL by having determine_optimal_proto() first test for connectivity with TLS 1.3 without checking for client authentication and then performing a separate check for client authentication using a non-TLS 1.3 protocol.
This commit only affects the flow of the program if a $URL_PATH is specified, the server supports TLS 1.3, and $OPENSSL supports TLS 1.3 but not -enable_pha.
testss.sh may still provide incorrect information about client authentication if a $URL_PATH is provided, the server is TLS 1.3-only, and LibreSSL is used.
Based on initial testing, this commit improves the check for client authentication in the case that the server only requests client authentication for specific URLs. However, it does not work correctly if the server supports TLS 1.3 and $OPENSSL is a version of LibreSSL that supports TLS 1.3 in s_client. The problem is that LibreSSL does not support post-handshake authentication with TLS 1.3
As noted in #1709, some servers will only request client authentication if a specific URL is requested. This commit modifies the check for client authentication, in the case that a $URL_PATH is provided, by having testssl.sh perform a GET request on the URL provided on the command line.
This commit adds the use of tls_sockets() to run_tls_fallback_scsv() to perform testing when the --ssl-native flag is not used. With this commit, run_tls_fallback_scsv() only uses tls_sockets() instead of $OPENSSL if the ClientHello needs to include the TLS_FALLBACK_SCSV flag, but it is not supported by $OPENSSL, or if the protocol that would be negotiated is SSLv3 and $OPENSSL does not support SSLv3.
There is at least one server that will not negotiate TLS_DHE_* cipher suites with TLS 1.2 and below if the supported_groups extension is present but does not include any DH groups. This commit adds the DH groups that are currently in the TLS 1.3 ClientHello to the TLS 1.2 and earlier ClientHello.
If $connect_success is false, then sclient_auth() does not "return" any value, and the calling function treats this as if sclient_auth() had returned 0.
This commit fixes sclient_auth() so that 1 is returned if $client_success is false.
This commit changes prepare_tls_clienthello() so that the RSA-PSS algorithms are offered in the signature algorithms extension of TLS 1.2 and below ClientHello messages.
Under Darwin using LibreSSL it was not possible to test for session
resumption by session ID.
This fixes#2096 by checking not only the return value of the s_client
hello but also whether a probable certificate is being returned.
It is now being tested whether the binary locale exists and
there's a global introduced for that.
Also there's no fileout warning at this early stage anymore
as it leads to non-valid JSON.
This fixes#2103 in 3.1dev.
