2010-08-15Windows security issue:v2.1.2James Yonan4-3/+116
Fixed potential local privilege escalation vulnerability in Windows service. The Windows service did not properly quote the executable filename passed to CreateService. A local attacker with write access to the root directory C:\ could create an executable that would be run with the same privilege level as the OpenVPN Windows service. However, since non-Administrative users normally lack write permission on C:\, this vulnerability is generally not exploitable except on older versions of Windows (such as Win2K) where the default permissions on C:\ would allow any user to create files there.

2010-08-05Fix multiple configured scripts conflicts issue (version 2)David Sommerseth1-0/+18
This is a fix for trac ticket #20, <https://community.openvpn.net/openvpn/ticket/20> which was started in the sf.net bug tracker: <http://sourceforge.net/tracker/?func=detail&aid=2078470&group_id=48978&atid=454719> The implemented solution is to give a warning for each of the different script hooks available. The last configured script will override any earlier configured scripts, to ensure that the command line can override the configuration file.

2010-08-02Exclude ping and control packets from activityDavide Brini3-7/+20
Problem: using --ping and --inactive together partially defeats the point of using --inactive as periodic ping packets are counted as activity. Here is the original discussion: http://article.gmane.org/gmane.network.openvpn.devel/3676 It turns out that "activity" is detected and recorded in two places in the code, both in forward.c: in process_outgoing_tun() for received packets, after they've been decrypted and sent to the TUN device; and in process_outgoing_link(), after they've been encrypted and written to the network socket. In the first case we can be sure that packets that get so far are really due to user activity, whereas in the second case there can be non-user packets (like OpenVPN's internal ping packets, and TLS control packets), and those should not be counted as activity as they are not coming from the user. So a need arises to detect those control packets and not count them as activity for the purposes of --inactive. Unfortunately, at that stage packets are already compressed and encrypted, so it's not possible to look into them to see what they are. However, there seems to be a convention in the code that packets whose buffer length in the context_2 structure is 0 should be ignored for certain purposes. TLS control packets follow that convention already, so this patch makes a small change in the code that generates the ping packets to set their buffer length to 0 as well. Finally, the call to register_activity() in process_outgoing_link() is made conditional to the buffer length being > 0. According to my tests, now --inactive behaves correctly according to the configured parameters (time or time+bytes) even when --ping is being used. forward.c: Call register_activity() in process_outgoing_link() only if the packet is not a ping or TLS control packet. openvpn.8: Updated the description of --inactive to describe the new semantics. ping.c: Set c->c2.buf.len = 0 after the ping packet has been generated and encrypted.

Solves bug ticket 13 <https://community.openvpn.net/openvpn/ticket/13> When the client sends PUSH_REQUESTS, it waits until the server sends PUSH_REPLY. If the server do not have anything to push to the client nothing happens. The client will then regularly send new PUSH_REQUESTS until it gets an answer, which results in not completing the connection negotiation.

2010-05-16OCSP_check.sh: new check logicDavid Sommerseth1-10/+32
contrib/OCSP_check/OCSP_check.sh: I discovered that, quite surprisingly, the exit status of "openssl ocsp" is 0 even if the certificate status is "revoked". This means that the logic of the script needs to be rewritten so that it parses the output returned by the query and explicitly looks for a "0x<serial number>: good" line, and exit if either the command has a non-zero exit status, or the above line is not found. Doing that portably without bashisms requires some juggling around, so perhaps the code is slightly less clean now, but it does have many comments.

2010-05-04ssl.c: fix use of openvpn_run_script()'s return valueFabian Knittel1-13/+5
This patch fixes two bugs introduced in commit 339f2a4d4b487afa53fa99d72c35b16f31e417d3 Author: David Sommerseth <dazo@users.sourceforge.net> Date: Thu Apr 29 23:35:45 2010 +0200 David's patch replaced openvpn_execve() with openvpn_run_script() in two places, but didn't adjust the return value handling. openvpn_run_script() returns true or false, while openvpn_execve() returns the program's exit code. Without the fix, the --tls-verify script and the --auth-user-pass-verify script fail to run. (I noticed the latter, but haven't actually tested the former.) The return value handling is fine for the other places where openvpn_run_script() is used, because those places previously used openvpn_execve_check() (notice the "_check" suffix).

2010-04-29Revamped the script-security warning logging (version 2)David Sommerseth8-11/+27
The main task of this patch is to avoid reporting the SCRIPT_SECURITY_WARNING over and over again, in addition to not show this warning when it should not be a problem. This general warning should now only appear once, and only when --script-security is not set, 0 or 1. In all other cases this warning should not appear. In addition, this warning will come close to the script-hook which most probably will fail. It will also give a little bit more concrete hint on which script-hook which failed. If --script-security is 2 or 3, only the execve failure itself will be shown. This message will on the other hand be shown repeatedly. This is a new rewritten version which simplifies the implementaion of the new openvpn_run_script() function. It was considered to remove it completely, but due to code clearity and easy of use it was decided to make this function a static inline function instead. Anyhow, this function will enforce openvpn_execve_check() to be called with the S_SCRIPT flag. Patch ACKed on the developers meeting 2009-04-29.

2010-04-29Enhance contrib/pull-resolv-conf/client.{up,down} scriptsDavide Brini2-69/+64
Patch arrived from Davide Brini: - No more bashisms (AFAICT). Should work with any POSIX-compatible shell (which means "almost all reasonably recent shells"), though I've only tested with bash and dash. - Unnecessary calls to external tools (sed) removed - Manages multiple DNS and DOMAIN options. Each DNS option becomes a "nameserver" line in the new resolv.conf (up to a maximum of 3). If there's a single DOMAIN option, it becomes a "domain" line in resolv.conf; otherwise, all the domains are listed in a "search" line in resolv.conf (eg "search foo.com example.net"). - Client.up renames the existing resolv.conf and creates a brand new one; client.down restores it from the saved copy when the VPN terminates (the usual rules about running as root apply). This is how Gentoo does that; the old scripts instead added/removed some lines at the beginning of the file, which looks a less clean approach to me. The rename approach also dramatically simplifies and shortens client.down, as you'll see. - Uses resolvconf if it's available (detected by the presence of /sbin/resolvconf) rather than writing to resolv.conf directly. Not sure whether this is a Linux-only thing or other systems use it though. Script has been smoke tested on Fedora 12 with OpenVPN 2.1.1 without the resolvconf package , and in addition Debian Lenny with OpenVPN 2.1_rc11 according to the patch.

By hardening the create_temp_filename() function to check if the generated filename exists and to create the temp file with only S_IRUSR|S_IWUSR bit files set before calling the script, it should become even more difficult to exploit such a scenario. After a discussion on the mailing list, Fabian Knittel provided an enhanced version of the inital patch which is added to this patch. This patch also renames create_temp_filename() to create_temp_file(), as this patch also creates the temporary file. The function returns the filename of the created file, or NULL on error.

2010-04-29Allow 'lport 0' setup for random port bindingEnrico Scholz1-1/+1
I am running a multihomed host where 'local <extip>' must be specified for proper operation. Unfortunately, this implies 'lport 1194' or another static port. This causes problems with stateful firewalls which register the host/port pairs in the internal connection tracking table. On ungraceful reconnects, the new TCP connection will have same the host/port pairs but unexpected sequence numbers. The new connection will be assumed as invalid hence and be dropped. It would be nice when local port can be configured to be bound to a random port number. After reading code, | else if (streq (p[0], "lport") && p[1]) | ... | port = atoi (p[1]); |- if (!legal_ipv4_port (port)) |+ if (port != 0 && !legal_ipv4_port (port)) | { in options.c seems to be the only required change.

With --verb 5, openvpn logs a single letter (rwRW) for each package received or sent. I recently ran into a problem with the tun device on Linux where the read from that device returned 0. Unfortunately this was also logged as "r", which made me assume that openvpn had received something, while it actually hadn't. (See https://dev.openwrt.org/ticket/6650 for the bug that made me find out about this problem with openvpn.) I'm attaching a patch which prevents openvpn from logging "r" or "R" when it didn't actually read anything. This is against openvpn 2.1-rc20, but probably still applies to the most recent version.

2010-04-29[PATCH] Change verify-cn so cn is no longer hardcoded in openvpn's config fileKarl O. Pinc1-15/+27
This patch should be easy to process. A resubmission of the patch sent to this list on 04/23/2009. The patch changes the verify-cn script sample to be used with --tls-verify so that instead of having to hardcode a cn to verify in the OpenVPN configuration file the allowed cns may be written into a separate file. This makes the process of verifying cns a whole lot more dynamic, to the point where it is useful in the real world. One problem with this patch is that it is backwards incompatible. I did not bother keeping the original calling interface as A) it's a sample script, and B) the original's functionality seems useless and equalivant functionality is easily available with the new script. The problem with the original is that there seems little point in verifying a client's cn when all the clients share one cn, as would have to be the case when the cn is hardcoded into the openvpn config file. This patch applies against the testing allmiscs branch, and should apply against any of the other testing branches as well. It works for me. I've tested it throughly but not used it extensively in production.

2010-04-27Enhance contrib/pull-resolv-conf/client.{up,down} scriptsDavide Brini2-69/+64
Patch arrived from Davide Brini: - No more bashisms (AFAICT). Should work with any POSIX-compatible shell (which means "almost all reasonably recent shells"), though I've only tested with bash and dash. - Unnecessary calls to external tools (sed) removed - Manages multiple DNS and DOMAIN options. Each DNS option becomes a "nameserver" line in the new resolv.conf (up to a maximum of 3). If there's a single DOMAIN option, it becomes a "domain" line in resolv.conf; otherwise, all the domains are listed in a "search" line in resolv.conf (eg "search foo.com example.net"). - Client.up renames the existing resolv.conf and creates a brand new one; client.down restores it from the saved copy when the VPN terminates (the usual rules about running as root apply). This is how Gentoo does that; the old scripts instead added/removed some lines at the beginning of the file, which looks a less clean approach to me. The rename approach also dramatically simplifies and shortens client.down, as you'll see. - Uses resolvconf if it's available (detected by the presence of /sbin/resolvconf) rather than writing to resolv.conf directly. Not sure whether this is a Linux-only thing or other systems use it though. Script has been smoke tested on Fedora 12 with OpenVPN 2.1.1 without the resolvconf package , and in addition Debian Lenny with OpenVPN 2.1_rc11 according to the patch.

Alon Bar-Lev indicated commit f27bf509315a48b0070294c3993a718df0c2626c was missing proper dependency checking. This patch corrects this and fixes an issue when creating configure.h via make distcheck. This is an enhanced version of the one sent to the openvpn-devel mailing list April 13, 2010 [1], after having received some feedback from Gert Doering, cleaning up configure_log.awk further.

2010-04-19Enhance contrib/pull-resolv-conf/client.{up,down} scriptsDavide Brini2-69/+64
Patch arrived from Davide Brini: - No more bashisms (AFAICT). Should work with any POSIX-compatible shell (which means "almost all reasonably recent shells"), though I've only tested with bash and dash. - Unnecessary calls to external tools (sed) removed - Manages multiple DNS and DOMAIN options. Each DNS option becomes a "nameserver" line in the new resolv.conf (up to a maximum of 3). If there's a single DOMAIN option, it becomes a "domain" line in resolv.conf; otherwise, all the domains are listed in a "search" line in resolv.conf (eg "search foo.com example.net"). - Client.up renames the existing resolv.conf and creates a brand new one; client.down restores it from the saved copy when the VPN terminates (the usual rules about running as root apply). This is how Gentoo does that; the old scripts instead added/removed some lines at the beginning of the file, which looks a less clean approach to me. The rename approach also dramatically simplifies and shortens client.down, as you'll see. - Uses resolvconf if it's available (detected by the presence of /sbin/resolvconf) rather than writing to resolv.conf directly. Not sure whether this is a Linux-only thing or other systems use it though. Script has been smoke tested on Fedora 12 with OpenVPN 2.1.1 without the resolvconf package , and in addition Debian Lenny with OpenVPN 2.1_rc11 according to the patch.

By hardening the create_temp_filename() function to check if the generated filename exists and to create the temp file with only S_IRUSR|S_IWUSR bit files set before calling the script, it should become even more difficult to exploit such a scenario. After a discussion on the mailing list, Fabian Knittel provided an enhanced version of the inital patch which is added to this patch. This patch also renames create_temp_filename() to create_temp_file(), as this patch also creates the temporary file. The function returns the filename of the created file, or NULL on error.

With --verb 5, openvpn logs a single letter (rwRW) for each package received or sent. I recently ran into a problem with the tun device on Linux where the read from that device returned 0.

2010-04-01[PATCH] Change verify-cn so cn is no longer hardcoded in openvpn's config fileKarl O. Pinc1-15/+27
This patch should be easy to process. A resubmission of the patch sent to this list on 04/23/2009. The patch changes the verify-cn script sample to be used with --tls-verify so that instead of having to hardcode a cn to verify in the OpenVPN configuration file the allowed cns may be written into a separate file. This makes the process of verifying cns a whole lot more dynamic, to the point where it is useful in the real world. One problem with this patch is that it is backwards incompatible. I did not bother keeping the original calling interface as A) it's a sample script, and B) the original's functionality seems useless and equalivant functionality is easily available with the new script. The problem with the original is that there seems little point in verifying a client's cn when all the clients share one cn, as would have to be the case when the cn is hardcoded into the openvpn config file. This patch applies against the testing allmiscs branch, and should apply against any of the other testing branches as well. It works for me. I've tested it throughly but not used it extensively in production.

2010-03-16[PATCH] Change verify-cn so cn is no longer hardcoded in openvpn's config fileKarl O. Pinc1-15/+27
This patch should be easy to process. A resubmission of the patch sent to this list on 04/23/2009. The patch changes the verify-cn script sample to be used with --tls-verify so that instead of having to hardcode a cn to verify in the OpenVPN configuration file the allowed cns may be written into a separate file. This makes the process of verifying cns a whole lot more dynamic, to the point where it is useful in the real world. One problem with this patch is that it is backwards incompatible. I did not bother keeping the original calling interface as A) it's a sample script, and B) the original's functionality seems useless and equalivant functionality is easily available with the new script. The problem with the original is that there seems little point in verifying a client's cn when all the clients share one cn, as would have to be the case when the cn is hardcoded into the openvpn config file. This patch applies against the testing allmiscs branch, and should apply against any of the other testing branches as well. It works for me. I've tested it throughly but not used it extensively in production.

Many of the scripts in the openvpn source have their shell set to /bin/bash, but only two use bash features. The attached patch (against openvpn-2.1_rc9) sets the shell on the rest of the scripts to /bin/sh for better portability. The only scripts that actually require bash are contrib/pull-resolv-conf/client.{up,down} ; they use the ${!var} variable indirection feature. sf.net tracker: <https://sourceforge.net/tracker/?func=detail&aid=2040296&group_id=48978&atid=454721> Discussed on the IRC meeting March 4, 2010 in #openvpn-discussions. <http://thread.gmane.org/gmane.network.openvpn.devel/3242> Signed-off-by: David Sommerseth <dazo@users.sourceforge.net> Acked-by: James Yonan <james@openvpn.net>

2010-03-02enhance tls-verify possibilityMathieu GIANNECCHINI6-0/+87
It should be nice to enhance tls-verify check possibilities against peer cert during a pending TLS connection like : - OCSP verification - check any X509 extensions of the peer certificate - delta CRL verification - ... This patch add a new "tls-export-cert" option which allow to get peer certificate in PEM format and to store it in an openvpn temporary file. Peer certificate is stored before tls-script execution and deleted after. The name of the related temporary file is available under tls-verify script by an environment variable "peer_cert". The patch was made from OpenVPN svn Beta21 branches. Here is a very simple exemple of Tls-verify script which provide OCSP support to OpenVPN (with tls-export-cert option) without any OpenVPN "core" modification : X509=$2 openssl ocsp \ -issuer /etc/openvpn/ssl.crt/RootCA.pem \ -CAfile /etc/openvpn/ssl.capath/OpenVPNServeur-cafile.pem \ -cert $peer_cert \ -url http://your-ocsp-url if [ $? -ne 0 ] then echo "error : OCSP check failed for ${X509}" | logger -t "tls-verify" exit 1 fi This has been discussed here: <http://thread.gmane.org/gmane.network.openvpn.devel/2492> <http://thread.gmane.org/gmane.network.openvpn.devel/3150> <http://thread.gmane.org/gmane.network.openvpn.devel/3217> This patch has been modified by David Sommerseth, by fixing a few issues which came up to during the code review process. The man page has been updated and tmp_file in ssl.c is checked for not being NULL before calling delete_file().

2010-03-01Allow 'lport 0' setup for random port bindingEnrico Scholz1-1/+1
I am running a multihomed host where 'local <extip>' must be specified for proper operation. Unfortunately, this implies 'lport 1194' or another static port. This causes problems with stateful firewalls which register the host/port pairs in the internal connection tracking table. On ungraceful reconnects, the new TCP connection will have same the host/port pairs but unexpected sequence numbers. The new connection will be assumed as invalid hence and be dropped. It would be nice when local port can be configured to be bound to a random port number. After reading code, | else if (streq (p[0], "lport") && p[1]) | ... | port = atoi (p[1]); |- if (!legal_ipv4_port (port)) |+ if (port != 0 && !legal_ipv4_port (port)) | { in options.c seems to be the only required change.
