Is there an issue with Sophos Intercept X and Internet Explorer 11?

We have seen Internet Explorer crash on every machine we install Sophos Interecpt X on. All of the Computers are Windows 10 (ver 1709).

 

We have had to change main browsers because of the constant crashing. On first opening it crashes on my own machine everytime. I have checked the LoadAppInit_DLLS in the registry and both are 0 (following on from another thread I read here).

 

Any idea what to try?  I have gathered some dumps of the crashes but don't have the experience to look at them.

 

Thank you

  • I've given the definition of insanity a run for its money trying to get to the bottom of this same issue also.

    Our EMR will only run in IE due to high dependency on ActiveX.

    Anytime Microsoft pushed out significant updates to Win10, I would have to reconfigure the internet security options under trusted sites on those workstations browsers. 

    Recently, IE would just trigger a message (Internet Explorer has stopped working) - and I have spent at least 10 hours since the new year trying every trick I know to get our users running stable. 

    Finally, when parsing through event logs I noticed a common trend in that C:\Program Files (x86)\Internet Explorer\IEXPLORE.EXE & C:\WINDOWS\system32\dinput8.dll were common denominators and searched that string. I landed on the Microsoft TechNet discussion where almost everyone there had an additional common factor - they all use Sophos!

    We purchased licenses for Intercept X for a reason, and now the only work around is to disable that protection on Windows 10 workstations? The renaming of the hitman .dll - is that an alternative? What exactly needs to be done in that case?

     

  • "The renaming of the hitman .dll - is that an alternative?"

    John, the component "Hitman Pro Alert" is InterceptX.  So the DLL mentioned just prevents IX from loading.

    Support did mention DINPUT8.DLL to me when the examined my logs.  They were like "this is what's crashing, so it's a Microsoft issue."  OMG!!  No, it's a Sophos issue.

  • Thanks for that point of clarification David.

    I just removed one of the windows 10 workstations I had assigned Int X on via Managed Endpoint Software that was problematic, rebooted and shes running fine now - with no crashing issues.

     

     

    Its obviously not a Microsoft issue!

    I've added this to the list of topics to discuss with our account manager, account executive, sophos engineer, and upgrade/renewals staff @Sophos on our next review call. 

  • I'm waiting to hear back from the end-user, but I saw first hand IE crashing whenever he loaded it (I even had Shockwave disabled as well).  I thought maybe it was something to do with his home page which was MSN (Lenovo) so I changed it to Google and IE didn't crash when opening.  Had him access his main sites and everything was working.

    If it continues to work (which I'll report back on), maybe check to see what home page the user has. 

  • If anyone has any dumps of the iexplorer.exe process from the crashes, having installed procdump as per my previous post on this thread, can you install Windbg either from the SDK or even Windbg Preview from the Microsoft Store.  After doing so can you paste the contents of running the command:
    !analyze -v
    It will be interesting to see if everyone is seeing the same error.

    Regards,
    Jak



  • I'm experiencing the same issue described here.  IE11 is crashing on any page that contains Flash.  I can produce it regularly by going to http://get.adobe.com/flashplayer/about/ and checking the version of Flash installed.  It does not crash every time but if I refresh 10 times it will crash maybe 6 or 7 of those.

  • I'll try and add a number of "changes" that help.  Maybe others can confirm:

    1. Setting tab growth of IE, such that iexplore.exe is set o use a single process. 

    Here is a reg key for all users on the computer.  You could do this on a per user basis using HKCU instead...

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main]
    "TabProcGrowthDefault"="Medium"
    "TabProcGrowth"=dword:00000000

     Note: TabProcGrowth can be a string or a DWORD.  I initially had it as a String and set to Medium.  As a test I have made it a DWORD and set it to 0.   See: https://blogs.msdn.microsoft.com/askie/2009/03/09/opening-a-new-tab-may-launch-a-new-process-with-internet-explorer-8-0/ for more info.

    2. If I:
    Stop the "HitmanPro.Alert service".
    In the registry under: HKEY_LOCAL_MACHINE\SOFTWARE\HitmanPro.Alert\_profiles_\Browsers\
    Set all the mitigations to 0 apart from ASLR, which is set to 1. 
    Start the "HitmanPro.Alert service".
    Then I can, with a script launch IE 50 times without issue with the homepage set to http://get.adobe.com/flashplayer/about/ 

    This suggests to me, the issue is with one or more of the mitigations, either in isolation or in combination.

    I will run through the tests toggling individual mitigations on.  If at the end I can set all of the values to 1 individually that will suggest it's more tricky than any one mitigation causing this.  Maybe a race condition?
