Install / Update Browser Installed on PSM Server and Configure Azure Portal Connector for Platform

Bynetsec

Mar 10, 2024

CyberArk plugins and Connection Components use web drivers to connect to web-based targets.

For the connection to succeed, the driver and browser versions must be the same.
This applies to both Chrome and Edge drivers.

Browser

Download info

Google Chrome (32-bit), version 100 or later

Click here to download this version

Microsoft Edge (32-bit), version 103 or later

Click here to download this version

To prevent incompatibility issues with the PSM Webapp infrastructure, with every new browser version update, make sure to also update the browser’s driver with the same version. For example, when updating the Chrome browser to version 104, the Chrome driver on the machine must also be updated to version 104.

Download and install the latest driver:

  • For Google Chrome, use this link to download the latest stable 32-bit (x86) driver.

  • For Microsoft Edge, use this link to download the latest stable 32-bit (x86) driver.

Copy the relevant downloaded exe file, Chromedriver.exe or msedgedriver.exe to the PSM Components folder.

<optional>  if Chrome browser is needed to reinstall, uninstall current Chrome from control panel first and download 32bit chrome browser from below link to install.

https://chromeenterprise.google/intl/en_US/browser/download/#windows-tab

2. Go to Chrome driver download page using below URL and download matching version of driver.

https://chromedriver.chromium.org/downloads. 

3. Move the downloaded chromedriver.exe file to Component folder of PSM installation location. By default, it’s location is below:

C:\Program Files (x86)\CyberArk\PSM\Components

4. Right click on the chromedriver.exe file -> Select Properties -> Check the “Unblock File” checkbox -> Click Apply/Ok to save.

5 Re-run powershell command  PSMConfigureAppLocker.ps1 under C:\Program Files (x86)\CyberArk\PSM\Hardening to generate a new hash for Chromedriver.exe

 Restart the PSM server and test the connection.

Note: https://cyberark.my.site.com/s/article/How-to-update-Chrome-Driver-in-PSM-server

=======================================================================

Step 1) Update Chrome browser, remember chrome should be a 32 bit version installed in the Program Files (x86) path.

Step 2) Download the latest chrome driver for your new version:
https://chromedriver.chromium.org/downloads

Step 3) Copy the chromedriver.exe to …\PSM\Components, overwrite the previous file.

Step 4) Check the marketplace to see if there are any newer versions of the Secure Web Application Connectors Framework. If there are, Download the latest and copy the zip to the PSM(s)

> https://cyberark-customers.force.com/mplace/s/#a3550000000EiCMAA0-a3950000000jjUwAAI

Step 5) Take a backup of the PSM’s components folder, copy paste it to your desktop (just in case).

Step 6) Copy only the contents of the components folder from the downloaded file from the marketplace (only the components folder, we don’t need any other folder contents). Copy these files to …\PSM\Components and overwrite files if prompted.

Step 7) Open the …\PSM\PSMHardening.ps1 script in a text editor, and check the value of $SUPPORT_WEB_APPLICATIONS. make sure it is set to: $true

Step 8) From Administrative Powershell, Run …\PSM\Hardening\PSMHardening.PS1

Step 9) From Administrative Powershell, Run …\PSM\Hardening\PSMConfigureAppLocker.PS1

Step 10) Test your connections from PVWA

Note: If still having issues, restart the PSM, hardening often requires a reboot.

Download / Update Browser Driver in PSM

1. Download the WebDriverUpdater tool from CyberArk’s marketplace:
https://cyberark.my.site.com/mplace/s/#a35Ht000000rjXlIAI-a39Ht000001kceVIAQ
*This tool operates independently as a standalone and portable application.*

2. Unzip the downloaded file and place it on your PSM server.

3. Update the “PathToPSMDrivers” field value in the “WebDriverUpdater.exe.config” file to point to the PSM Components folder. (Default location: C:\Program Files(x86)\CyberArk\PSM\Components)

4. Execute the WebDriverUpdater.exe as an administrator. Review the logs folder to confirm successful web driver updates.

5. Ensure rules for chromedriver\msedgedriver are added to PSMConfigureAppLocker.xml:

chromedriver: <Application Name=”chromedriver” Type=”Exe” Path=”C:\Program Files (x86)\CyberArk\PSM\Components\chromedriver.exe” Method=”Hash” />

msedgedriver:  <Application Name=”msedgedriver ” Type=”Exe” Path=”C:\Program Files (x86)\CyberArk\PSM\Components\msedgedriver.exe” Method=”Hash” />

*You can configure the Method to “Publisher” for future compatibility and to prevent AppLocker from blocking future updated versions of the drivers.

6. Execute the PSMConfigureAppLocker.ps1 script as an administrator located in the Hardening folder.


*If you prefer not to utilize the tool, an alternative method is available for downloading the drivers specific to your installed Chrome or Edge browser. You can obtain the drivers by visiting the following links:

Chrome driver: https://github.com/GoogleChromeLabs/chrome-for-testing/blob/main/data/known-good-versions-with-downloads.json (Search for the Chrome version that installed on the PSM server and download the relevent chromedriver) 

Edge driver: https://msedgewebdriverstorage.z22.web.core.windows.net/?form=MT00IS (Click on “Next” you find the folder for the Edge version that installed on the PSM server)

Place the downloaded file in the PSM Components folder. (Default location: C:\Program Files(x86)\CyberArk\PSM\Components) and follow steps 5-6.

Onboarding Azure AD Accounts for Azure Portal

Note: https://docs.cyberark.com/PAS/10.10/en/Content/PASIMP/PSM-Azure-CloudServicesManagement.htm
To get Azure Portal connector working, we will need to install Google Chrome and ChromeDriver
Step 1:
1. Download ChromeDriver.exe (Matching your chrome version, usualy it is x86)
  • for older version before 115: https://chromedriver.chromium.org/downloads
  • for newer version after 115: https://googlechromelabs.github.io/chrome-for-testing/
2. Put it into C:\Program Files (x86)\Cyberark\PSM\Components
Step 2:
1. Install chrome using script
It is inside your CyberArk Privilege Cloud Tools package: Cyberark PrivilegeCloud Tools-v13.3\Cyberark PrivilegeCloud Tools\Add-PSMApps
2. Unzip Add-PSMApps
3. Run script Add-PSMApps.ps1 from PowerSHell administrator window
It will automatically download Chromex86 version and add it with ChromeDriver into allow-list by AppLocker.

Now we can switch PSM server for testing Connect to Azure Portal

Onboarding Azure AD Accounts with MFA

Since Azure Portal login will need MFA, there are a couple of changes will need to make on Connector:

Remove validation in web form:
Disable Validation

Enable Trace:

From platform, disable default PSM-MS-AzurePortal and add new PSM-51SEC-AzurePortal

You will need to wait 0-3 minutes to get those connector configuration re-loaded into PSM server.

Troubleshooting

PSM WebApp unable to locate webform fields

Issue / Details

Describe in the requestor’s words – what are they trying to do, what is not working, or what are they are looking for?

PSM WebApp is unable to locate web form fields under the following conditions:

  1. The target web application uses invalid/untrusted self signed certificate.
  2. PSM chrome browser hardening in place.
  3. PSM chrome browser version (including chrome browser driver) is 102 and above.

 You may encounter the following error when launching chrome browser from PSM server to the target web application server in concern.

 

 Resolution

The answer or the steps taken to resolve the issue.

Workaround solution :

————————

  1. Set SSLErrorOverwriteAllowed to yes (value of 1) under Chrome browser hardening at the PSM server. If you using GPO, make sure you set the correct setting. By default, we set this to no (value 0) in our PSM chrome browser hardening
  2. Ensure that EnforceCertificateValidation is set to “No” in the PSM-PVWA webApp connector. The default is set to yes.
  3. Change the webform connection component webform settings to add the first two action below highlighted in red:

details-button>(button)(searchby=id)

proceed-link>(click)(searchby=id)

pvBody_PageTemplate_innerHolder_ctrlLogon_txtUsername>{username} (searchby=id)

pvBody_PageTemplate_innerHolder_ctrlLogon_txtPassword>{password}(searchby=id)

LogonButton>(Button)(searchby=class)


Restart your PSM services or wait 10 minutes. 

The default PSM parameter, refresh interval, is 10 minutes. In version 10, you can control it in Administration | Options | Privileged Session Management | General Settings | Server Settings | Configuration Refresh Interval = 600 seconds.

——————————————–
Permanent solution:
———————————————
This issue would be fixed next version of PSM Secure Web Application framework (version 12.7) marketplace plugin which will be released in the next future.

Look out for the availability of version 12.7 at the CyberArk marketplace : https://cyberark-customers.force.com/mplace/s/#a3550000000EiCMAA0-a3950000000jjUwAAI
———————————————–

Note: The above solutions will lower the security posture of the PSM server for webApp connection components. The recommendation solution is to ensure that all managed web applications are installed with CA signed certificates or Trusted self signed certificates.

PSM – After updating Google Chrome on the PSM, Chrome-based connection components fail to connect

Issue / Details

Describe in the requestor’s words – what are they trying to do, what is not working, or what are they are looking for?

The PSM Web App Dispatcher fails to interact with Google Chrome version 69, although it successfully worked with Chrome versions 62 to 64. 

The following error appears:

PSMSR605E Error occurred while waiting for the dispatcher to communicate (Error details: [PSMSR606E Timeout occurred while waiting for a specific component to end]) 


For Chrome version 89, see Article Chrome 89 update | upgrade breaks PSM functionality.

PSM

Cause

The underlying cause of the issue. Cause is an optional field as it is not appropriate or necessary for some types of articles.

The cause for the problem is the DisableDeveloperTools group policy. When set to Yes, as in the Chrome hardening shipped with PSM, it prevents the dispatcher application from interacting with the Chrome 69 browser and performing the secured login. Setting DisableDeveloperTools to No resolves this problem. 

The Developer Tools window itself remains inaccessible to the user due to the URL Blacklist policy that also exists in the shipped Chrome hardening. 

Resolution

The answer or the steps taken to resolve the issue.

If the environment uses In-Domain hardening (by applying the CyberArk Hardening – In Domain) : 

1. Open Group Policy Management Editor (Run -> gpmc.msc) and login to the domain the PSM server is joined to. 

2. Expand the relevant domain node. Under Group Policy Objects locate the GPO where the CyberArk In-Domain hardening policies are applied. 

3. Right-click on the GPO and then click on “Edit…” 

4. In the opened editor window, navigate to: 

Computer Configuration > Policies > Administrative Templates > Classic Administrative Templates (ADM) > Google > Google Chrome. 

Click on the Google Chrome node to select it. 

5. Set the Disable Developer Tools setting to Not Configured. 

6. Run the command gpupdate /force on all relevant PSM machines. 

 

If the environment does not use In-Domain hardening: 

1. Logon to the PSM machine. 

2. Navigate to Hardening directory under the PSM installation path. For example: C:\ProgramFiles (x86)\CyberArk\PSM\Hardening. 

3. Open the file PSMChromeHardening.csv in a text editor 

4. Replace the following line: 

Software\Policies\Google\Chrome,DeveloperToolsDisabled,REG_DWORD,1 

with: 

Software\Policies\Google\Chrome,DeveloperToolsDisabled,REG_DWORD,0 

5. Save the changes and close the text editor. 

6. Open a cmd window As Administrator and navigate to the same Hardening directory as earlier. 

7. In the cmd window, run the following command: GroupPolicyLoader.exe machine PSMChromeHardening.csv PSMChromeHardening.log 

8. Run the following command: gpupdate /force 

9. Repeat the process for each relevant PSM machine. 

 

Note: The user will not be able to open the Developer Tools since they are blocked for user access by the URL Blacklist policy. 

Our Chrome hardening allows only URLs beginning with http:// https:// and ftp://. 

This causes internal Chrome windows such as chrome://settings, chrome://flags, etc. to be inaccessible, and the same holds for the Developer Tools window (this has been tested before recommending the procedure) – with the URL policy in place, the user cannot access Developer Tools from the menu or using the hotkeys. 

Troubleshooting – Parameter BrowsePath is invalid

https://cyberark.my.site.com/s/article/Failed-to-initialize-web-browser-The-selected-browser-was-not-found

When tried to launch Azure Portal Connection, it failed with this message. 

By default it is using x86 32b chrome path. If you installed 64b chrome, you will need to make browser path change:

Each change, you might need to wait 5-10 minutes to take the changes into effect. 

Troubleshooting – Failed to initialize web browser. 


Failed to initialize web browser, the selected browser was not found. Validate that the browser is installed, excluded for the hardening and the parameter “BrowserPath” is configured correctly.

Secpol.msc
Disable applocker, but it will be enforced again after PSMConfigureAppLocker.ps1 runs.

We can check those executable rules and dll rules for which dll was in the exceptions. 

You also can check event viewer to see any error for AppLocker

You might find ChromeDriver.exe was prevented running.

In this case, you will need to add following line into PSMConfigureAppLocker.xml

<!– Google Chrome process –>
 <Application Name=”GoogleChrome” Type=”Exe” Path=”C:\Program Files\Google\Chrome\Application\chrome.exe” Method=”Publisher” />
 <Application Name=”GoogleChromeDriver” Type=”Exe” Path=”C:\Program Files (x86)\Cyberark\PSM\Components\chromedriver.exe” Method=”Hash” />

Then re-run PSMConfigureAppLocker.ps1

No need to run hardening script and it will take effect right away.
