Adding custom HTTP headers to a proxy'ed HTTP request when stunnel is used as an endpoint for a HTTP proxy
by Tony Cheneau 02 Sep '18

02 Sep '18

Good evening folks, Michal was kind enough to review and rewrite/integrate one of my patches for logging session IDs [1] and post the remaining ones on the website [2]! So, I feel I should also contribute to this list a little program I wrote. It is meant to be used with the exec= directive. It is mostly useful when stunnel is used to secure a connexion between a client and a HTTP proxy. A stunnel instance can run locally on the client while a stunnel server runs on the HTTP proxy: HTTP client (proxy'ed) <- > stunnel client <--> stunnel server <-> HTTP proxy Here, the "exec=" program will run on the stunnel server and add some extra headers to each HTTP request. One of this headers is the client's Distinguished Name (from its X.509 certificate). The HTTP proxy (squid for example) can then make some decision based on this HTTP header (authorisation, etc.). It relies heavily on PicoHTTPParser. Regards, Tony Cheneau [1]: to appear in version 5.49, see https://www.stunnel.org/sdf_ChangeLog.html [2]: patches 0002 and 0003 on https://www.stunnel.org/patches.html

OpenSSL 1.1.1 secure level and also an old problem rearing up
by Peter Pentchev 26 Aug '18

26 Aug '18

Hi, Sorry to be the bearer of a "those OS vendors did something again and now we have to catch up with them... again..." type of news, but, well, the maintainers of the Debian package of OpenSSL upgraded it to a prerelease 1.1.1 version and, in the process, changed the default cipher selection in the openssl.cnf file to 'SECLEVEL=2'. Unfortunately, this means that the server certificate used in the stunnel test suite is not considered strong enough, so the test suite is failing. More details may be found in the description of the Debian bug https://bugs.debian.org/906981 and the error message itself is at https://ci.debian.net/data/autopkgtest/testing/amd64/s/stunnel4/865956/log.… (look for all the lines containing "SSL_CTX_use_certificate:ca md too weak") So my first reaction was to stop running the stunnel test suite and only leave my functional test script; however, I then had another idea and tried to get the stunnel test suite to explicitly specify SECLEVEL=1 using the attached patch. This actually helped a bit - it made most of the tests pass - but then I hit a problem with e.g. 037_failover_prio1: if there is a "ciphers" option in the config file, stunnel eventually dies with an error that I seem to remember having seen before; take a look at this gdb backtrace from stunnel 5.48: (gdb) bt #0 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 #1 0x00007f0a349882f1 in __GI_abort () at abort.c:79 #2 0x000055b1aa3ad645 in fatal_debug (txt=0x55b1aa3c503c "Bad magic", file=0x55b1aa3ca6dd "ssl.c", line=118) at log.c:379 #3 0x000055b1aa3ae066 in get_alloc_list_ptr (ptr=0x7f0a24014520, file=0x55b1aa3ca6dd "ssl.c", line=118) at str.c:429 #4 0x000055b1aa3ae229 in str_detach_debug (ptr=ptr@entry=0x7f0a24014520, file=file@entry=0x55b1aa3ca6dd "ssl.c", line=line@entry=118) at str.c:378 #5 0x000055b1aa3ae884 in str_detach_debug (line=118, file=0x55b1aa3ca6dd "ssl.c", ptr=0x7f0a24014520) at str.c:413 #6 str_free_debug (ptr=0x7f0a24014520, file=0x55b1aa3ca6dd "ssl.c", line=118) at str.c:413 #7 0x00007f0a34f7661a in CRYPTO_free_ex_data () from /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1 #8 0x00007f0a35112a98 in SSL_SESSION_free () from /usr/lib/x86_64-linux-gnu/libssl.so.1.1 #9 0x00007f0a34f7a1bc in OPENSSL_LH_doall_arg () from /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1 #10 0x00007f0a35114177 in SSL_CTX_flush_sessions () from /usr/lib/x86_64-linux-gnu/libssl.so.1.1 #11 0x000055b1aa3c3701 in unbind_ports () at stunnel.c:439 #12 0x000055b1aa3c3799 in main_cleanup () at stunnel.c:224 #13 0x000055b1aa3ad720 in main (argc=<optimized out>, argv=<optimized out>) at ui_unix.c:79 (gdb) (the line numbers may be a bit off from the stock stunnel source, since I also added a setrlimit(RLIMIT_CORE, infinity) patch) So, yeah, what would be the best way forward here? I guess I might create a new certificate specifically for the Debian package's test suite, but I think the double-free problem may also need to be fixed. Let me know if you need any more information about reproducing it or any more data in case it doesn't happen on your end. Thanks for everything you're doing for stunnel, and keep up the great work!

Log to syslog without process name, after reloading the configuration (sighup)
by Reschke, Sven (VWIF G-TS/P) 22 Aug '18

22 Aug '18

Hi, I've upgraded my stunnel from version 5.44 to 5.45. After reloading the configuration of stunnel (via pkill -sighup stunnel) several times, I've stumbled about missing syslogs. Only the loading of the configuration file was still visible. Then I've noticed, that greping the syslog for stunnel was my mistake. Stunnel doesn't log its process name after reloading the configuration file the second time (see logs below) Can someone verify, or is it just me, or some configuration I'm missing? BTW: I've reproduced the "problem" also for the version 5.48 as you can see from the logs. With version 5.44 stunnel always logged its process name to syslog. Syslog output for greping after "stunnel": Aug 17 13:41:14 <user> stunnel: LOG5[ui]: stunnel 5.48 on armv7l-unknown-linux-gnueabihf platform Aug 17 13:41:14 <user> stunnel: LOG5[ui]: Compiled/running with OpenSSL 1.0.2p 14 Aug 2018 Aug 17 13:41:14 <user> stunnel: LOG5[ui]: Threading:PTHREAD Sockets:POLL,IPv6 TLS:ENGINE,FIPS,OCSP,PSK,SNI Aug 17 13:41:14 <user> stunnel: LOG5[ui]: Reading configuration from file /home/pi/stunnel.conf Aug 17 13:41:14 <user> stunnel: LOG5[ui]: UTF-8 byte order mark not detected Aug 17 13:41:14 <user> stunnel: LOG5[ui]: FIPS mode disabled Aug 17 13:41:14 <user> stunnel: LOG4[ui]: Insecure file permissions on /home/pi/psk.txt Aug 17 13:41:14 <user> stunnel: LOG4[ui]: Insecure file permissions on /home/pi/psk.txt Aug 17 13:41:14 <user> stunnel: LOG5[ui]: Configuration successful ---------------- Reloading the configuration the first time ----------------------- Aug 17 13:41:21 <user> stunnel: LOG5[main]: Reading configuration from file /home/pi/stunnel.conf Aug 17 13:41:21 <user> stunnel: LOG5[main]: UTF-8 byte order mark not detected Aug 17 13:41:21 <user> stunnel: LOG5[main]: FIPS mode disabled Aug 17 13:41:21 <user> stunnel: LOG4[main]: Insecure file permissions on /home/pi/psk.txt Aug 17 13:41:21 <user> stunnel: LOG4[main]: Insecure file permissions on /home/pi/psk.txt Aug 17 13:41:21 <user> stunnel: LOG5[main]: Configuration successful ---------------- Reloading the configuration a second time ------------------------ Aug 17 13:41:26 <user> : LOG5[main]: Reading configuration from file /home/pi/stunnel.conf My configuration file: [PSK client] client = yes accept = <listen address> connect = <remote address> PSKsecrets = /home/pi/psk.txt [PSK server] accept = <listen address> connect = <remote address> PSKsecrets = /home/pi/psk.txt Sven Reschke Embedded System SW Developer G-TS/P Volkswagen Infotainment GmbH Universitätsstr. 140 44799 Bochum Mobile +49 1525-887 2762 sven.reschke(a)volkswagen-infotainment.com<mailto:sven.reschke@volkswagen-infotainment.com> http://www.volkswagen-infotainment.com<http://www.volkswagen-infotainment.com/> Sitz der Gesellschaft: Wolfsburg Amtsgericht Braunschweig: HRB 204780 Geschäftsführung: Bernhard Krauße (Sprecher), Tobias Nadjib

Re: [stunnel-users] Is there a way to specify certificate content in stunnel config
by Eric S Eberhard 24 Jul '18

24 Jul '18

Use stunnel in inetd mode. Execute a script (or better C program). Copy the certificates for making the stunnel connection to a directory that is OK … then delete them immediately after stunnel starts. Hack – but might be OK for what you are doing. I am not sure why anyone would think it more secure to put the keys into the stunnel command than to just use them from a file … but I likely do not know enough about your application to make a judgement.

Grok log parsing
by Manuele Trimarchi 24 Jul '18

24 Jul '18

I would ask if someone use Grok log parsing for stunnel and, if yes, what kind of filter statement are you using? At the moment I've just created 2 parser: STUNNEL_AcceptedConnectionParser %{date("yyyy.MM.dd HH:mm:ss"):date} LOG%{integer:loglevel}\[%{integer:session_id}\]\: Service \[%{word:csb_name}\-%{word:csb_port}\] accepted connection from %{ipv4:caller_ip}\:%{port:caller_port} and STUNNEL_ConnectionClosedParser %{date("yyyy.MM.dd HH:mm:ss"):date} LOG%{integer:loglevel}\[%{integer:session_id}\]\: Connection closed\: %{integer:byte_tx} byte$s$ sent to SSL\, %{integer:byte_rx} byte$s$ sent to socket I'm new with Grok and all the things related to log match-and-parse, so I think that there will be a much better solution than mine, anyway Google this time doesn't help unfortunately. Thank you so much to all those who will help me with this stuff! Manuele

by Jaymin D 24 Jul '18

24 Jul '18

Hi All, I want to cross compile the Stunnel-5.48 for my Android AOSP (arch64) platform using BoringSSL's 'libssl.so' and 'libcrypto.so' libraries. I have successfully cross compiled the BoringSSL in my AOSP and both .so file was generated for arch64 platform. Am using BoringSSL which was delivered with Android AOSP (Android 7). Am cross compiling using "build-android.sh" script.
