Script to Install & Update Zoom

[omatsei]

We use Zoom a lot, so I modified a script that we were using for Firefox (Thanks Joe Farage!) to install or update to the newest version of Zoom. This one enables HD video, sets SSO logins to be default, and configures the URL for SSO. Below is the script:

Tested this script and has worked fine. Autopkg has been having an issue with the Zoom recipe recently, so I may just start using the script for the near future.

[brady_ingledue]

Works great, thank you!!!

[landono]

While this script works perfectly for updating, for some reason Zoom hangs on the login screen when re-opening. If you close the window and open it again it's fine though. Anyone else running into this?

[ssuttle]

This script is great! Thank you!

[greatkemo]

@omatsei how about using this link to download the latest? https://zoom.us/client/latest/ZoomInstallerIT.pkg

This is taken from the documentation page here https://support.zoom.us/hc/en-us/articles/115001799006-Mass-Deployment-with-Preconfigured-Settings-f...

Cheers!

[jrserapio]

@landono I am running into this as well. Are you using SAML SSO, if so who is your IdP?

[jrserapio]

I did another review of the script, and appears the plist is not being moved from /tmp/ to where it should be?

Edit NVM. Not sure why single sign on options are not working as intended using SAML.

[jmjenki3]

Wonderful script!

I've been looking into setting audio output options for Zoom. For some reason, Zoom seems to ignore my device outputs, even if I set the output by hand. I've looked into setting outputs by switchaudiosource, and it while it does set the output on the device, Zoom doesn't respect the setting.

I also browsed through the plist configuration options here: https://support.zoom.us/hc/en-us/articles/115001799006-Mass-Deployment-with-Preconfigured-Settings-for-Mac

While there were a lot of good settings there, I didn't see anything about setting a default audio output. Has anyone been able to set audio output, and have zoom respect that, and keep the setting?

[jbellez]

hmm, I've tried using this but the install errors out when installing via self service. Seems to work ok when trying to run via terminal.

Anyone else running into issues? this is with both High sierra and mojave.

I package the following preinstall and postinstall scripts in a payload-free package using Packages app. Hope it helps.

[tlarkin]

I would urge everyone to look at something like AutoPKG to build the packages for you and then something like JSS Importer to automate the integration into jamf. Running curl scripts on endpoints as root is really not a great practice

[jbellez]

ok that is bizarre.

I made a copy of the script I had for firefox (based on the same one this script is based on). I manually made the edits to do the install only, and this works fine now.

I had tried to just take the script in the OP but that doesn't seem to work. must have had a character somewhere causing it to error out.

Now i need to do a modification to add the preferences.

[greatkemo]

Anyone deploying Zoom, needs to read this:

Zoom Zero Day: 4+ Million Webcams & maybe an RCE? Just get them to visit your website!

[jwojda]

Unless I'm misunderstanding, the DOS and disable camera by default is part of the current versions? So we can just patch the app at this point?

[bsatterthwaite]

@greatkemo Funny you post that, as I was reading it last night before heading to bed, so I could get this addressed today. Personally, I don't like the way it does things so I have been looking for an excuse/justification to force our users to stop using it. This may do the trick =)

[AdamCraig]

@greatkemo @bsatterthwaite there is another thread addressing the zero day exploit: https://www.jamf.com/jamf-nation/discussions/32561/zoom-exploit#responseChild187189

[donmontalvo]

Zoom client 4.4.53932.0709 resolves the vulnerability.

Apple's X-protect update prompts the user to "Allow".

Combine these two, and this should be a nothing-burger.

[tlarkin]

@jwojda

Unless I'm misunderstanding, the DOS and disable camera by default is part of the current versions? So we can just patch the app at this point?

The big problem is, that when you uninstalled it, it left the web server intact. So, it sorta made you even "less secure" when the app was removed. The current version, claims to fix this.

[Nix4Life]

Hey Nation, can we confirm if Apple pushed an XProtect or a MRT update to fix this? not seeing the XProtect update @donmontalvo mentioned in my SUS

ty

[donmontalvo]

@Nix4Life Do you get 1.45?

@donmontalvo

Yes, also hope the earthquake did not affect anything for you

[donmontalvo]

Oh crap I relocated to FL in October...better update my profile. :)

[omatsei]

It looks like Zoom updated their versioning, at least the newest version (it contains parentheses now, so that's fun). I updated my script to the following, which seems to be working... no promises though. As always, please test before deploying large-scale.

Also, note that this is for Penn State, so you'll have to update your SSO URL depending on your environment.

HI @omatsei - I tried running your updated script a few minutes ago and got some strange behavior. Zoom was not installed on the machine, I ran the script, and at the end, the current version of the zoom client was installed. However, the script returned exit code 1 for some reason. In the script log, the script reports that the update was unsuccessful, and zoom remains uninstalled. The app does work at the end though.
Here is the terminal output, as well as the contents of the zoominstallscript.log:

Any ideas?

@eprice Same here! It seemed to work fine a week or two ago but I'm now getting the same error email. Not the end of the world since it seems like the install happens, but strange nonetheless.

[tlarkin]

So I don't package or create policies to patch and deploy zoom. That is all automated. Again, I highly recommend AutoPKG (or AutoPKGr ) + JSS Importer to fully automate your package deployment.

I open sourced my policy model and JSS Importer templates for patching, you can view it here

Replacing CFBundleShortVersionString with CFBundleVersion in the original script worked for me. CFBundleVersion reports the version "old style", 4.5.3284.0829 for the currently latest version. Needs to be changed in 2 places in the script, "currentinstalledver = ...." and "newlyinstalledver = ..." lines.

[JMenacker]

@olev_mj GREAT catch, replacing "CFBundleShortVersionString" with "CFBundleVersion" in those two places resolved on our end as well. Thanks!

[semurphy]

Each time this script runs it appends to the plist, not constructing a new one. Even if I delete it, it will come back with all old additions. Anyone experience this? How do I ensure each time this script runs (as I use it for forced upgrades) it's adding to the plist!

[tlarkin]

Zoom is a signed and notarized app, if you alter the Info.plist you will break app signing and the app will not work FYI. I broke Zoom recently altering the version string trying to test update UX, just a FYI

[omatsei]

Sorry, I haven't been able to keep this updated as much as I would have liked. Many thanks to @olev_mj for finding the version bug! The full newest version, that seems to work for me, is the following:

I changed line 62 and 138 to check the current version without the new formatting from Zoom.

/usr/bin/defaults read /Applications/zoom.us.app/Contents/Info CFBundleShortVersionString

to

/usr/bin/defaults read /Applications/zoom.us.app/Contents/Info CFBundleShortVersionString | sed -e 's/0 //g' -e 's/(//g' -e 's/)//g'

I am sure there is a more elegant solution but this is now running without producing an error.

[tlarkin]

Posted: 7/2/2019 at 6:49 PM CDT by tlarkin I would urge everyone to look at something like AutoPKG to build the packages for you and then something like JSS Importer to automate the integration into jamf. Running curl scripts on endpoints as root is really not a great practice

Just wanted to post this as a reminder. curl scripts on endpoints is a pretty risky move

[ekarazhov]

Hello guys, this is an awesome script thank you for that. However i have a question. This script only updates and installs zoom application, but in our environment we use zoom outlook plug in as well. is there any way to incorporate that in to that script as well?

[gachowski]

I don't think Zoom recommends the plug in on Catalina ...

[stephen_watson]

When I run this script from Terminal it works fine, but when I run it a script policy in Jamf it fails. The log file is empty.
I updated the script to remove SSO, otherwise, everything else is the same. Ideas?

# Set preferences
hdvideo="true"
ssodefault="false"
ssohost=""

[thebeard]

@ekarazhov You can deploy the plugin now though the O365 Admin portal. It will deploy to all clients (you will need to remove the old version) and be available to outlook on the web as well.

[GregE]

Anyone else getting this error after it has done an update?
Runs fine in terminal, but doesn't like it as part of the script
/usr/bin/defaults read /Applications/zoom.us.app/Contents/Info CFBundleShortVersionString

[stephen_watson]

Thanks @thebeard a handy little add-in for Outlook, but this doesn't help if I need to join someone else's Zoom meeting.
