Microsoft Edge can not open any website or page when contained/sandboxed

Product Discussions XCS - Xcitium Client Security

Since I can not find the bug report session in the forum, I put it here.

Steps:

  1. Sandboxed the Microsoft Edge browser (Latest chromium-based version) in the containment of XCS.
  2. Try to open any website.

Results:
Microsoft Edge can not open any website or page when contained/sandboxed.

Version:

  1. Windows version: Windows 11 x64 22H2
  2. XCS version: 12.13.0.9089

Additional note:
This bug was found when I was using CIS, however, there has been no response or fix even though I has reported it in the old CIS forum years ago. Today when I tried XCS, I found this issue also existed in the latest version.

Besides, google chrome and other chromium-based browsers don’t have this issue when sandboxed in the containment. Since Microsoft Edge has been integrated as the default browser in Windows 10 and Windows 11, I think this issue should be fixed.

I also reported this before that edge has no connection in containment.

@QuickSilverST The developer explains that this issue is due to “XCS does not allow access to COM/DCOM for contained applications by default”. However, Edge NEED to access COM/DCOM.

The solution is manually adding the Edge application into the exclusion of ‘Do not restrict access to COM/DCOM for apps’ in the advanced setting of containment.

C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe

It works well here. However, I’m unsure whether this operation will induce potential security risks since Edge application can access the COM/DCOM. If the Edge is utilized by malware…
