Hello @to759_PM That should already be resolved, thank you!

Hi,

Can you confirm that this is only an issue when running an install or upgrade rather than an ongoing issue in an already-installed environment? Or is there a component of the installer that can be leveraged (perhaps via uninstaller) to expose this?

Thanks

Hello @AlexOmetis

Let me get clarity on this for you.

All the best,
Sonja

Looking at the Release Notes which lists the bug, it seems it's to do with leaving MSI files on disk that would be accessible to non-admins... which I guess means it affects existing installs too. Although this doesn't sound like a "race condition" as described in the security bulletin.

QV-25114

Local Privilege Escalation

Installers sometimes left .msi files on Local disc, which could result in a security problem. This is now fixed, so that administrator rights are needed to access them.

Also clarity on whether it affects QlikView Server AND QlikView Desktop or just one or the other would be useful.

@Sonja_Bauernfeind

What kind of events can be caused by being able to run with administrator privileges?
For example, is it possible for the system to be stopped or destroyed without permission?

Thanks.

@sis Adding your question to our investigation.

In the email of our Qlik partner is stated "If successfully exploited, a user with existing access to the Windows environment running QlikView or the QlikView plugin may be able to escalate their privileges to that of administrator."

What is meant here with "QlikView plugin"? Is there a vulnerability related to this plugin?
