clipboard functionality

[KarlHalpin]

Hi Guys,

Bit of a weird one but has anyone experienced issues with office add ins that uses the clipboard functionality?

seem to be having intermittent errors with it and it just straight up not working.

Tried removing the cortex agent from one or two systems and it seemed to have restored clipboard functionality to the add in, one still did continue with errors after it was removed though.

I cant see any logs in cortex that would suggest it was blocking this so I am not 100% sure cortex is causing the issue but i just thought i would ask here and see if anyone had anything similar.

Agent version is 7.7.8

Hi @KarlHalpin 
I see that you have mentioned agent version as 7.7.8. 
It seems there is a typo, i believe you are referring to agent version 7.8 as there is no 7.7.8 version.

May I check what is the build version of XDR agent 7.8 you are using on problematic endpoints.

In this new version of XDR agent 7.8 there were some known issues identified with regards to clipboard functionality.
This issue has been fixed in latest build version of XDR agent 7.8.0.64264

If your agent lower than the version 7.8.0.64264, to resolve this issue, can you please upgrade or reinstall with this version.

Create a new agent installation package with version 7.8.0.64264 or above.

Then use this package to install or upgrade the agent on problematic endpoint.
Then monitor the endpoint to see if you are still facing the issue.


As per below article, you can find more information on the clipboard issue with 7.8 XDR agent version.

Please let me know the results of above actions. 

Mark this as solution as an answer if it helped to solve the problem you are facing.
Thank you!

We are seeing similar clipboard issues in Excel only after endpoints upgrade to 7.8.0.64264. We are getting errors that the clipboard is full and there's a problem with the clipboard.

Hi @jruck 

Ideally this issue should not be occurred with XDR agent version 7.8.0.64264 or above as per article shared.
The issue with clipboard functionality already addressed in this specific version.

However if you are still facing this issue with 7.8.0.64264, I would request you to log a support case to investigate this issue further.

Aside to above, you can also try downgrade to version 7.7.2 by uninstalling agent with 7.8.0.64264 and installing 7.7.2 version agent on the machine.

I hope that answers your query.

Yes I have opened a support case. The clipboard error goes away when uninstalling the Cortex Agent. We are only seeing the issue on Windows 10 clients after the upgrade to 7.8.0.64264 so I suspect the fix CPATR-17723 that was for Windows 7 and Windows 2008 R2 has introduced the issue to a new clipboard issue to Windows 10 endpoints.
