Access Server release notes for 2.1.12 (changes made since 2.1.9)

 

* Problems with gaps in sequentially ordered lists of keys in the configuration database are now automatically repaired when using sacli start on the command line.
* TLS level 1.2 for the OpenVPN protocol is labeled the default for new installations. Upgrades of existing installations remain at the previously set level.
* TLS level 1.1 for the web services is labeled the default for new installations. Upgrades of existing installations remain at the previously set level.
* SSLv2 and SSLv3 support has been deprecated and will be removed completely in a future release.
* SSL settings page is now renamed to TLS settings page, since TLS is now the prevalent technology and SSL is phasing out.
* Alias interfaces like eth0:1 and such could not be selected for source NAT outgoing VPN client traffic. This bug has now been fixed.
* An option has been added to completely disable TLS auth. This should only ever be used for compatibility with clients that offer no way to implement TLS auth at all.

 

Access Server release notes for 2.1.9 (changes made since 2.1.8)

 

* Small code improvements, slightly faster response time on web interface.

Access Server release notes for 2.0.10 (changes made since 2.0.8)

 

 

*Fixed a bug in 2.0.8 when modifying user permissions that could potentially cause the user to disappear from queries, especially when setting the "Admin" flag on a user.

*Fixed bridging regression in 2.0.8 where instantiating the bridged tunnel was failing because of the introduction of two separately named openvpn binaries for OpenSSL and PolarSSL.

 

Access Server release notes for 2.0.8 (changes made since 2.0.7)

 

* Updated to OpenSSL 1.0.1h to address security issues.

* Added PolarSSL support as an alternative to OpenSSL for the OpenVPN protocol and integrated web server (In Admin UI, go to Configuration -> SSL Settings page).

* Added options to control minimum SSL/TLS versions for both the OpenVPN protocol and web server.

* Implemented HTTP Proxy support in OpenVPN Connect client on Windows.

In tray menu, go to Options -> HTTP Proxy -> Set to set the proxy address and port.  An auth dialog should pop up if proxy creds are required.

* In OpenVPN Connect clients for Windows and Mac, allow http-proxy and related directives to be specified in imported profiles, e.g.:

FULL LIST OF CHANGES:

 

* Initial AS IPv6 milestone — IPv4.Addr is now an IPv4/6 discriminated union

derived from ovpn3 (swig-wrapped) module.

 

* Added necessary swig patch to build ovpn3 python module.

 

* Fix Admin UI Cross-site request forgery (CSRF) vulnerability (CVE-2013-2692)

 

* Added Android and iOS client links to CWS.

 

* Fixed issue where pressing logout button from CWS would raise web exception.

 

* Add constant-time hash compare for authlocal module.

 

* Added “proto” parameter to VPNConnect and ovpncli tool, for selecting tcp/

udp transport protocol.

 

* Fixed issue where astatus.py would endlessly ask for EULA agreement.

 

* Changes to Admin UI “At a glance” sidebar:

 

1. To avoid CSRF attacks, start/stop link on Server Status row has been

replaced by “More” link which redirects to server status page where

server can be started/stopped.

 

2. Links in “At a glance” sidebar vanish when current page would be the

destination of link.

* Build Python with readline support.

 

* Changed pyovpn version number to 2.0.

 

* Changed all scripts that reference python version number to use 2.7.

 

* Fix to generation of iptables rules for DNS traffic:

 

Because generated iptables rules trap DNS requests early in ASx_IN_PRE

chain, if initial call to dns_server_subnets did not reduce the rules

to empty, we must instead use the whole list of non-reduced rules,

i.e. we cannot reduce them further based on access granted to private

subnets or the public internet.

 

* Added comment in LinuxIPv4Forward to extend to IPv6 so that

/proc/sys/net/ipv6/conf/all/forwarding is also set.

 

* Added CC_CMDS env var for debugging.  CC_CMDS is a comma-delimited list of

OpenVPN directives (such as iroute) to be appended to client-config list.

 

* Major IPv6 patch that addes IPv6 tunnel support to AS.

 

* Added Python-2.7 patch.

 

* Minor script updates.

 

* On Admin UI Current Users page, properly show both IPv4 and IPv6 addresses.

 

* Raised some string length limits from 128 and 256 to 512.

 

* Try to move AS default private subnets to RFC-1918 backwater.

 

Before:

 

“vpn.daemon.0.client.network”: “5.5.0.0″,

“vpn.server.group_pool.0″    : “5.5.16.0/20″,

 

Now:

 

“vpn.daemon.0.client.network”: “172.27.224.0″,

“vpn.server.group_pool.0″    : “172.27.240.0/20″,

 

* Fixed regression in usersvc.py related to regeneration of

Client object.

 

* Added post_auth script pasfp.py that shows connecting user, serial number,

CN, and SHA1 fingerprint of leaf cert.

 

* Fixed some instances where transport.write (in Twisted) might be called with

a unicode string, causing a Twisted exception. This was likely causing an

issue with failover rsync where the ssh password was being passed as unicode

to transport.write.

 

* Minor text updates to Admin UI:

 

1) Don’t cite LZO in compression settings because multiple compression

algorithms are now available.

 

2) Warn that layer 2 is incompatible with mobile.

 

3) Due to IPv6 address notation, ranges should now be delimited by ‘;’

instead of ‘:’.

 

* Because of tradeoff between Beast mitigation with RC4 and RC4′s own

weaknesses, turn off Beast mitigation by default, and change some of the

related text in the Admin UI. In particular, Beast flag now defaults to

false and is keyed by cs.beast_workaround2

 

* Added support for OpenVPN tls-version-min directive.

 

* Removed some debugging and redundant code.

 

* Added connect_timeout and server_poll_timeout parameters to Connect and

VPNConnect methods (and capicli and ovpncli tools).

 

connect_timeout (optional int|str) : set connection timeout (seconds)

 

server_poll_timeout (optional int|str) : set server-poll-timeout OpenVPN

parameter (seconds) — the number of seconds to try each remote entry before

moving on to the next

 

* The client backend as.conf can now specify a list of prepend and append

config file directives to be applied before and after the config file.

 

For example:

 

[capi]

 

prepend_config.0=route-method exe

prepend_config.1=route-delay 30

prepend_config.2=route-metric 512

prepend_config.3=route 0.0.0.0 0.0.0.0

 

* Minor change in clisite to use new method IP.is_lo() to test whether address

is a loopback address.

 

* Fixed issue where exceptions in AuthRPCServer._render_finalize were causing

server-side stack traces to be sent to client.

 

* Minor rewording of BEAST option in Admin UI for clarity.

 

* If vpn.server.routing.snat_source list is non-empty, use it to generate SNAT

interface list rather than enum_interfaces.
