Important: cPanel & WHM 11.36, 11.34, and 11.32 Security Releases

Posted on February 26, 2013 by Ken

cPanel has released new builds for all public update tiers. These updates provide targeted changes to address security concerns with the cPanel & WHM product. These builds are currently available to all customers via the standard update system.

cPanel has rated these updates as having important security impact. Information on security ratings is available at http://go.cpanel.net/securitylevels.

If your deployed cPanel & WHM servers are configured to automatically update when new releases are available, then no action is required. Your systems will update automatically. If you have disabled automatic updates, then you are highly encouraged to update your cPanel & WHM installs at your earliest convenience.

Releases

The following versions of cPanel & WHM address all know vulnerabilities:

  • 11.36.0.10
  • 11.34.1.11
  • 11.32.6.2

The latest public releases of cPanel & WHM for all update tiers are published at http://httpupdate.cpanel.net.

Security Issue Information

The resolved security issues were identified by the cPanel security team and independent security researchers. There is no reason to believe that these vulnerabilities are known to the public. As such, cPanel will only release limited information regarding the vulnerabilities at this time.

Once sufficient time has passed to allow cPanel & WHM systems to automatically update their installed software to the new versions, cPanel will release additional information regarding the nature of the security issues. These Targeted Security Releases address 3 vulnerabilities in cPanel & WHM 11.36 and 2 vulnerabilities in cPanel & WHM 11.34 and 11.32. Additional information is scheduled to be released February 27, 2013.

For information regarding our Versions and Release Process, please read the following document:

EasyApache 3.18 in 11.36

Posted on February 1, 2013 by Sarah

cPanel Inc., announces the release of EasyApache 3.18, our powerful and simple-to-use script that you can use to update and configure your Apache web server.

The most important feature of this new release is Apache 2.4, the latest version of the Apache web server. However, we have made a few important changes to Apache 2.4 to ensure as smooth an upgrade as possible for you, so it is important that you review the changes at: http://docs.cpanel.net/twiki/bin/view/EasyApache/Apache/Apache24Issues

The script wrappers for the Apache and PHP modules installed by EasyApache have been changed to handle the new Perl distribution.

Several important Apache modules have been upgraded and improved as part of this release, such as ModSecurity and ModHostinglimits.

And as part of our overall documentation improvement effort, we have moved EasyApache’s documentation to a new directory at http://docs.cpanel.net/twiki/bin/view/EasyApache/

For more details, please visit our EasyApache Release Notes at http://docs.cpanel.net/twiki/bin/view/EasyApache/

cPanel & WHM 11.36, CURRENT Tier Release

Posted on January 28, 2013 by Sarah

January 28, 2013
Houston, TX-

cPanel Inc., announces the release of cPanel & WHM 11.36 to the CURRENT tier.

Included in this brand new release are further improvements to the update system, building on work started with cPanel & WHM 11.30. A new staging step during installation allows a variety of checks to occur prior to changing the cPanel & WHM installation. This makes both new installation, and upgrades, more reliable.

cPanel & WHM 11.36 also brings an entirely new system for managing applications, based upon the tried-and-true RPM packaging format. By distributing applications via RPM we are able to reduce cPanel & WHM installation time by 30%, on average. The new system also provides integrators and system deployers a simplified means of distributing applications with cPanel & WHM.

We are happy to announce that cPanel & WHM 11.36 brings a modern version of Perl with it. Perl 5.14 is available with all versions of 11.36 and newer. This change brings an end to the older Perl 5.8.8 distributed with prior versions of cPanel & WHM.

This release also lays the groundwork for Apache 2.4, which will appear shortly with the release of EasyApache 3.18.

Other features are also available in version 11.36:

The Email Auto Discovery feature, first introduced in cPanel & WHM 11.34, has been updated with improved compatibility with existing setups.
It is now possible to display the number of files used by an account, in the cPanel Stats Bar.
The ability to track mail sent by web applications is improved through new functions to query the web server, and with X-PHP-Script functionality added to PHP.

cPanel thanks the members of our EDGE-Users community for their feedback and testing of the development releases. If you would like to join this community please GO HERE: http://cpanel.net/mailing-lists/.

For more details, please visit our Release Site: http://releases.cpanel.net
and our Documentation Notes: http://docs.cpanel.net/twiki/bin/view/AllDocumentation/1136ReleaseNotes

Please note, after upgrading to the new release, a downgrade to an older version will not be permitted.

End of Life for cPanel & WHM 11.30

Posted on January 25, 2013 by Sarah

This is the notification of the End of Life for cPanel & WHM 11.30

The 18-month lifetime of cPanel & WHM 11.30 ends now. The last release of cPanel & WHM 11.30, being 11.30.8.0, will remain on our mirrors indefinitely. You may continue using this last release, however no updates for version 11.30 will be released going forward. Older releases of cPanel & WHM 11.30 will be removed from our mirrors.

cPanel strongly recommends that you migrate any existing installs of cPanel & WHM 11.30 to a newer version (either 11.32 or 11.34).

If you have a server setup that complicates migrating to a newer version of cPanel & WHM, for example an out-of-date operating system, cPanel is here to help. Please open a support ticket via https://tickets.cpanel.net/submit/. Our professional support staff will help with recommendations, migration assistance and more.

For more detailed information regarding End of Life:

cPanel Security Release 11.34.1.7

Posted on January 14, 2013 by Sarah

cPanel has published a new security release, 11.34.1.7, containing Rails and ProFTPd security fixes. We recommend that all affected customers on the CURRENT, RELEASE, and STABLE tiers update to 11.34.1.7 as soon as possible.

This release addresses two major vulnerabilities with Ruby on Rails (CVE-2012-5664 and CVE-2013-0156) which are resolved in Rails 2.3.15, and one with ProFTPd (CVE-2012-6095) which is resolved in ProFTPd 1.3.5rc1.

phpMyAdmin has also been upgraded from 3.5.3 to 3.5.5.

Please note that, for the Rails update, this release provides the new version but does not remove any previous versions. It is therefore of great importance for any customers using software that currently depends on Rails 2.3.14 to ensure that it uses 2.3.15 moving forward in order to avoid remaining vulnerable.

You may check which version(s) of the Rails and Action Pack gems you have installed using the gem list command.

Example:

# gem list | grep -e actionpack -e rails
actionpack (2.3.15)
rails (2.3.15)

IPv6 Implementation Update

Posted on January 11, 2013 by Sarah

State of IPv6 in cPanel & WHM
IPv4 IP allocation depletion is somewhat analogous to Y2K. The solution is essentially the same, except instead of going from 2 to 4 decimal digits in a year, we’re going from 32 to 128 binary digits in IP addresses while still supporting the old system. cPanel & WHM will continue to support IPv4 for the foreseeable future by means of a “dual-stack implementation” which includes support for IPv6 addresses while still accommodating IPv4 addresses.

Much like Y2K, this issue requires a proactive solution rather than a reactive response. That is why cPanel has been working diligently on research and analysis to incorporate IPv6 support into our products. In 2013 we will begin to deliver features that support IPv6.

As some of you may already know, IPv6 is much more than just a change in the addressing scheme. However, given the urgency of supporting IPv6 addressing, we will first focus on allowing you to manage manually assigned IPv6 addresses at least as well as you can currently manage IPv4 addresses in cPanel & WHM. We also look forward to supporting IPv6 addresses on NSD, MyDNS and BIND (for DNS functionality), Apache (for website functionality), cPanel & WHM and its related services, and the various mail services we support. Additional services will be made IPv6-capable as deemed fit. The level of support cPanel will provide for IPv6 will provide functionality needed for serving web content.

BUT WAIT, THERE’S MORE!
Unlike Y2K, this is not simply a matter of fixing software. While your workstation likely supports IPv6 and cPanel-powered hosting providers will have software that supports IPv6, everything between your computer and the server running cPanel & WHM needs to support IPv6 as well. This means that your Internet provider, your cPanel & WHM server’s data center, and all the servers and routers in between must support IPv6. Otherwise, for you, IPv6 essentially does not exist.

To see if your Internet connection currently has an IPv6 address, visit: Test your IPv6 Connectivity.

Data centers around the world hope to explore and resolve IPv6 compatibility issues among their networks as part of World IPv6 Day. The Internet Society coordinates this event and you can learn more about it at: World IPv6 Day Information.

In the meantime, if you run a data center, you may find it beneficial to check your firewalls and other network infrastructure to ensure that they are as robust with IPv6 as they are with IPv4. There have been several industry reports of network hardware malfunctions with IPv6, such as firewalls improperly filtering IPv6 traffic. Please take the time to ensure that your network infrastructure can reliably support IPv6-capable versions of cPanel & WHM.

Lastly, you can join cPanel community members for IPv6-related discussions here: cPanel & WHM IPv6 Discussion.

ModSecurity Changes

Posted on December 27, 2012 by Sarah

cPanel recently released EasyApache 3.16. This version of EasyApache contains an updated version of ModSecurity that has an important change to Rule IDs which will affect you.

In addition to the RuleID change, another change in ModSecurity that affects directive names will be incorporated into EasyApache 3.18.

Unique Rule IDs are mandatory

Unique Rule IDs are mandatory. When EasyApache runs, it tries to automatically assign unique Rule IDs to any existing rules that do not already have Rule IDs. However, you will need to manually check your ruleset to confirm that there are no Rule ID conflicts or syntactical errors.

Also, if you automatically download and import rulesets into your ModSecurity on a schedule, EasyApache will not check these rules for Rule ID conflicts or syntactical errors. If the third-party ruleset contains Rule ID conflicts or syntactical errors, ModSecurity will fail and Apache will not start.

The following is an example of a rule that does not contain a Rule ID:

 SecRule  REMOTE_ADDR  "^127.0.0.1$"  "nolog,allow"
SecAction  "phase:2,pass,nolog"

You will see an error similar to the following:

 1. Critical Error: No Rule ID

  Syntax error on line XX of /some/config/file.conf:
  ModSecurity: No action id present within the rule

The following is the same rule that has been changed to include a unique Rule ID:

 SecRule  REMOTE_ADDR  "^127.0.0.1$"  "nolog,allow,id:1234123455"
SecAction  "phase:2,pass,nolog,id:1234123456"

However, if the Rule ID duplicates another Rule ID, you will see:

 2. Critical Error: Duplicate Rule ID:

  Syntax error on line XX of /some/config/file.conf:
  ModSecurity: Found another rule with the same id

Configuration directive changes

Six configuration directives have been changed to use the word “Hash” instead of “Encryption” and they are not backwards-compatible.

EasyApache will try to convert all references within your existing ruleset from “Hash” into “Encryption.” However, if you automatically download and import rulesets into your ModSecurity on a schedule, EasyApache will not check these rules for the deprecated term “Encryption.” ModSecurity does not support the deprecated term “Encryption” and it will fail, which will make Apache fail to start.

The following is an example of a rule that used the deprecated term “Encryption”

# Validates requested URI that matches a regular expression.
SecRule REQUEST_URI "@validateEncryption product_info|product_list" "phase:1,deny,id:123456"

You will see an error similar to the following

Syntax error on line XX of /usr/local/apache/conf/modsec2.conf:
Invalid command '@validateEncryption', perhaps misspelled or defined by a module not included in the server configuration

The following is an example of the example rule that has been changed to use the new term “Hash”

# Validates requested URI that matches a regular expression.
SecRule REQUEST_URI "@validateHash product_info|product_list" "phase:1,deny,id:123456"

——-

These two changes are important because if you have any rules which ModSecurity cannot process, ModSecurity will fail and Apache will not start. This is a change from ModSecurity’s previous behavior, which was to fail with a warning, but allow Apache to start successfully.

For more information, read the ModSecurity Page.

Prepare Your Perl Scripts for 11.36

Posted on December 13, 2012 by Sarah

In 11.36, cPanel will ship with a distribution of Perl 5.14.3. This version of Perl will be located inside the /usr/local/cpanel tree to avoid problems with the RPMs provided by the distro. While the installer will still require basic Perl, cPanel will no longer need /usr/bin/perl in order to function. System administrators will have the option to have the cPanel installer remove /usr/bin/perl all together. The cPanel code and /usr/bin/perl will have minimal interaction.

Warning: If the distro’s core Perl does not provide the modules, then you may need to change your shebang at the top of your scripts. This pertains especially to new installs. You will need to change your shebang if:

  • Your scripts need to work on all versions of cPanel (including 11.36).
  • Your maintenance scripts tie into the cPanel code.
  • You want to use Perl 5.14.

Based on specific needs, we recommend the following two options to change #!/usr/bin/perl at the beginning of your script:

Option 1: If the script needs to function in all versions of cPanel (including versions where Perl 5.14 wasn’t provided), we recommend the following:


#!/bin/sh
eval 'if [ -x /usr/local/cpanel/3rdparty/bin/perl ]; then exec /usr/local/cpanel/3rdparty/bin/perl -x -- $0 ${1+"$@"}; else exec /usr/bin/perl -x $0 ${1+"$@"}; fi;'
if 0;

#!/usr/bin/perl

Option 2: If the script needs to function only in 11.36 and later versions, you can simply change all of your scripts to point to the new version of Perl:


#!/usr/local/cpanel/3rdparty/bin/perl

Note: While /usr/local/cpanel/3rdparty/bin/perl is a symlink, we do not recommend that you use the binary that the symlink points to. This binary could be removed when a new version of Perl is issued.

cPanel and Attracta Relationship Redefined

Posted on December 10, 2012 by Sarah

For Immediate Release
December 10, 2012

Houston, TX-
cPanel officially announces that its partnership with Attracta has been redefined. The relationship between the two companies has now shifted from Attracta being bundled with cPanel to Attracta being included as part of cPanel’s third party application catalog.

Integrating Attracta as part of the cPanel distribution identified the difference between development cycles and processes between the two companies. Due to these differences in development, and both companies wanting to focus primarily on delivering new features and value to customers, Attracta will be distributing the Attracta SEO and Marketing Tools for cPanel & WHM as a standalone plugin rather than bundled with cPanel.

cPanel’s extensive plugin API allows Attracta to maintain all functionality going forward, while the separate distributions allow both companies to focus on adding more features and value without the overhead of a shared development process.

Asked for comment, Aaron Phillips, Vice President of Operations at cPanel stated: “We view this relationship as a positive learning experience for both cPanel and Attracta and we plan to maintain ongoing discussions that will continue our focus on the evolution of our API, and improvements for 3rd party integrators to make good use of”.

Many hosting companies include Attracta in their service offerings right now. For those that do not, but wish to have it, they can still get the plugin directly from Attracta’s website and seamlessly integrate it into cPanel.

“We’re ensuring a smooth transition for customers back to a standalone plugin and we’ve learned a lot about cPanel’s products during the course of the integrated relationship,” said Dave Koston, CTO at Attracta. “Both companies have gained knowledge from the integration that will allow us to deliver higher quality products going forward so we believe this will be a win for all our customers.”
