@Sonja_Bauernfeind can you share the location of the files that are being cleanup up by the patch? I have searched through a few QV installs and so far haven't found any MSI files in the Qlik folders in program data or program files. The only executable type files I have come across is .exe's.

@jeremyseipel

The .msi may be located in either:

C:\Users\<USER>\AppData\Local\Temp\{GUID}

C:\Users\ <User> \AppData\Local\QlikTech Installations\{GUID}

@Sonja_Bauernfeind What if we removed all .msi files from these location? Do we still need to upgrade to versions that contain the fix?

jeremyseipel · ‎2024-03-22

@QliksterMind you are thinking the exact same thing I was. For environments where you cannot easily get the downtime or if there is a case where a version of QlikView is older than the patches released, removing the files or locking down the folders would a work around.

@Sonja_Bauernfeind ......Any updates to the above messages? Is it just related to the MSI files?

Sonja_Bauernfeind · ‎2024-03-26

Hello @Qlik1983

We are still gathering and verifying the answers to give you the clearest possible response. I expect to have them for you today.

All the best,
Sonja

any news ?

Hello @xudo

The vulnerability is related to the MSI files.

@jeremyseipel @QliksterMind @Qlik1983 @mbrade

Regarding the question of Will deleting the MSI files mitigate the issue:

Qlik does not consider removing the MSI files a complete workaround as a user of the server could restore them.

As for the remaining questions, I am aiming to have them answered as soon as possible and will be updating the blog post with an FAQ accordingly.

All the best,
Sonja

@Sonja_Bauernfeind - thanks for the updates. However the answer regarding which products doesn't make much sense to me. MSI files are the installer files that are unpacked as part of the installation - they only come as part of a product install. Are you saying the MSI files for all QlikView installers were insecurely stored and that they could be used to elevate privilege for any of those installers?

It makes a big difference if we need to upgrade just QlikView Server or QlikView Desktop & Plugin as well to mitigate this issue. Also given that it's a local, not remote, vulnerability, the risk profile is very different for a server or a client as the server is less likely to have unprivileged users logging in that could abuse this vulnerability.

I get that upgrading all of them is the ideal solution, but more information on which installers, how the vulnerability can be exploited, any alternative mitigations etc would help customers & partners plan the right priorities on the components of the response.

Hello @AlexOmetis

I'm working on getting you a detailed response. I've also clarified the response in the thread to mirror the answer I gave in the FAQ as it is clearer than what I replied within the thread itself.

All the best,
Sonja

Hello @Sonja_Bauernfeind,

1. Is it possible for there to be no MSI file on the disk?
2. If there is no MSI file on the disk, is it unnecessary to perform the actions described in this article?

Environment: QlikView May 2022 IR

Best regards,
afujikawa
