• Enhanced current key sizes supported to include 1024, 2048, 3072, and 4096 bits.
• The AS web interface “Server” header now defaults to “OpenVPN-AS” and can be overridden using the config key cs.web_server_name
• Added 169.254.0.0/16 to the existing set of RFC 1918 subnets considered by the AS to be private.
• Added “X-Frame-Options: SAMEORIGIN” header to all AS Admin UI and CWS pages to prevent click-jacking.

• For new generated certs, use SHA256 instead of SHA1 as the cert digest algorithm.
• For new installs, set a default minimum TLS version of 1.0 for the web server. Existing installs can set the minimum TLS version on the SSL Settings page of the Admin UI.

OpenVPN Access Server 2.0.10

• 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.
  If affected by this issue, you can repair the DB by using the following command:
  /usr/local/openvpn_as/scripts/confdba -u –assign_type
• Enable tls-version-min directive in generated client profiles when “Select minimum TLS protocol version accepted by OpenVPN server” Admin UI setting is changed from its default value.
• Updated PolarSSL to 1.3.8.
• 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.

OpenVPN Access Server 2.0.8

• 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, for example:
  http-proxy ntlm.proxy.tld 3128 auto-nct
  <http-proxy-user-pass>
  myusername
  mypassword
  </http-proxy-user-pass>
• In OpenVPN Connect Windows client, integrated NDIS 6 TAP driver.

• On EC2, have ovpn-init automatically determine the public IP address of the instance, for setting the default public hostname. This only works if the instance is launched with a public IP, not when the public IP is attached later on.
• Added support for appliance initialization on the CloudSigma cloud platform.

OpenVPN Access Server 2.0.3

• Extended ACL and DMZ port settings to allow specification of a port range
• Fixed issue where an invalid port (or port range) specified for DMZ in the User Permissions page would be silently ignored, with no error message.
• Added a potential improvement on the iptables rule generation for DNS packets.
• Extended the “Allow Access To these Networks” field in User/Group Permission pages to allow the full route specification syntax supported by the backend, including subnets, services, port ranges, and NAT vs. Routing flag.

• Added necessary swig patch to build ovpn3 python module.
• Fix admin web interface cross-site request forgery (CSRF) vulnerability (CVE-2013-2692).
• Added Android and iOS client links to client web interface.
• Fixed issue where pressing logout button from client web interface 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 made to admin web interface “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.
• Update IPv6 AS branch to use Python 2.7.

• 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 adds 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.
• Moved AS default private subnets to RFC-1918 backwater.
• 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. 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
