Deploying and licensing EndNote X8

November 23, 2016 3 comments

As previously discussed, a number of folks in my shop use Clarivate Analytics’s EndNote bibliography software. Clarivate Analytics provides EndNote X8 with an installer application, but I need an installer package in order to easily deploy it to my customers. EndNote X8 was initially problematic in that regard, but I was able to write AutoPkg recipes for EndNote X8 to handle converting Clarivate Analytics’s installer application into a deployable installer package, including a recipe that would automate uploading the latest EndNote installers to my Casper server.

Once AutoPkg was able to provide an EndNote X8 installer package for deployment, the remaining hurdle was that the EndNote X8 installer from AutoPkg installs an unlicensed copy of EndNote and I needed to have installed copies of EndNote automatically use my shop’s EndNote site license.

Fortunately, EndNote X8’s volume license can be deployed just like EndNote X7’s volume license. The volume license is stored in as an invisible file named .license.dat in /Applications/EndNote X8  and it has a format that looks like this:

Company Name
1234567890
V2ZMQT6556P8WMH38MTQ6YSM8UXCCRYQ5MDS4WJGLKMP7RGSWECBCMT77556P8WCE8KMTQ6YSMNXJCCRYQ59MD9WJGLKMCSESSWECBCMB76556P8WCU3NMTQ6YSMLUYCCRYQ5MET8WJGLKMPSMJSWECBCM57F556P8WCU3CMTQ6YSM9DECCRYQ59XSCWJGLKMPNE9SWECBCMB79556P8WCH8KMTQ6YSMDXECCRYQ5MTSMWJGLKMPYRMSWECBCB7W7556P8W

Note: The Company Name part may show up twice in your .license.dat file.

With some additional testing, I found that I could remove an existing .license.dat file (if one was present) and replace it with my shop’s site license’s .license.dat file. That allowed me to use the EndNote X8 installer produced by AutoPkg by having Casper install it, then apply our site license file as a post-installation action. For more details, see below the jump.

In the wake of VMware’s release of ESXi 6.5, I was able to upgrade my ESXi 6.0 Update 2 server to ESXi 6.5 using SSH and esxcli. For those interested in doing likewise, please see below the jump for the details of the process I used.

Preparing EndNote X8 for deployment using AutoPkg

November 15, 2016 3 comments

As previously discussed here, one of the software packages used in my shop is Clarivate Analytics’ EndNote bibliography software.

Recently, EndNote X8 was released. When the new version’s installer was downloaded, it was discovered to be an installer application, which can pose problems for deployment.

By itself, the change to an installer application may not have been a huge problem as long as it had options for running the installation process from the command line. However, when I checked with EndNote support about the new installer, I was told that there was no option for installing EndNote X8 on a Mac using the command line.

Since the EndNote X8 installer does not have the option of command line installation, the only real option I thought I had was to install EndNote X8, then re-package it as either a drag-and-drop install or an installer package. However, when I dug deeper into the installer, I discovered a .zip file buried inside the installer.

When expanded, this .zip file proved to be a complete install of EndNote X8.

When I ran the EndNote X8 installer, it appeared to be performing the following functions:

1. Checking for Endnote updates
2. Extracting the .zip file into a new EndNote X8 folder

3. Moving the new EndNote X8 folder into /Applications

4. Launching the EndNote X8 application, which automatically loads the EndNote X8 Customizer screen if EndNote hasn’t been configured.

Providing website links via Casper Self Service policies

November 10, 2016 Leave a comment

It’s often useful to provide a way for everyone in your shop to be able to look up commonly used websites. Methods I’ve seen of doing this include:

  • Wiki pages
  • Bookmarks deployed to browsers
  • Browser extensions

Another method is to use Casper’s Self Service plug-ins feature.

This makes it easy to set up website bookmarks, which then appear in a sidebar of Self Service.

Self Service URL plug in

The main drawback to this method is you can’t scope these bookmarks to appear only to certain users or computers. These will appear on on all managed computers and to all users. If you need to have one set of bookmarks available to Group A in your organization, and a different set of bookmarks appearing to Group B, the Self Service plug-ins feature may not be the best solution.

Fortunately, you can solve this scoping issue using Casper policies and Self Service. For more details, see below the jump.

Race condition vulnerability fixed in CasperCheck

November 7, 2016 Leave a comment

Recently, I was alerted by Todd Houle that his infosec folks had identified an vulnerability with CasperCheck that should be addressed.

The problem:

CasperCheck downloads a QuickAdd installer from a web server inside a .zip file and initially stores it in the /tmp directory. All users on the system have access to /tmp, so it was possible for an malicious unprivileged user to leverage a race condition to replace the downloaded .zip file with another .zip file with the same name.

Assuming that the replaced .zip file was valid and passed the check for being a valid .zip file, CasperCheck would then expand the contents of the replaced .zip file into the /var/root/quickadd directory. Assuming that the malicious unprivileged user had their own installer package stored inside the replaced .zip file, the next time that CasperCheck would determine that it needs to install the Casper agent via its cached QuickAdd installer, it would instead install that installer package in place of the expected QuickAdd package.

The fix:

The vulnerability assumes that the QuickAdd package is being downloaded to a place where an unprivileged user can access it, so the implemented fix to this problem is to download it to a place where only root has access. Todd fixed the issue by changing the designated download location to the following:

From: /tmp/quickadd.zip
To: $quickadd_dir/quickadd.zip, where the value of $quickadd_dir is /var/root/quickadd

Moving the download location to /var/root/quickadd means that the download is going to a location inside the root account’s home directory. Only root has write access to its home directory, which stops an account which doesn’t have root privileges from being able to swap out the .zip file.

Changes to CasperCheck:

Fortunately, the changes needed to implement this fix are minor and are in two places:

The quickadd_zip variable has changed:

From: /tmp/quickadd.zip
To: $quickadd_dir/quickadd.zip, where the value of $quickadd_dir is /var/root/quickadd

The update_quickadd function has been updated, to move the following actions to be first:

  • The creation of the /var/root/quickadd directory, if that directory is not already present
  • The removal of existing files from the /var/root/quickadd directory

I’ve posted an updated CasperCheck script with the described changes to the following location:

https://github.com/rtrouton/CasperCheck/blob/master/script/caspercheck.sh

If you’re a CasperCheck user, I recommend updating to the latest version at your earliest convenience.

The changes to the script can be seen here:

Hat tip: Thanks to Todd to alerting me to this issue and providing help to fix it.
