.NET Framework Service Packs - All of a Sudden

Question asked by Charles Hill on Jun 1, 2018

Comment • 30

All of a sudden, in VM, I'm getting reports that .NET Framework 3.0 Service Pack 1 and .NET Framework 2.0 Service Pack 1 are not installed on all of my workstations (Agent-based reporting). Those are QIDs 90561 and 90559. The problem is, we have SP 2 confirmed as installed on everything, and Qualys knows it.

RESULTS: HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727 SP = 2

RESULTS: HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0 SP = 2

Nothing has changed in older .NET configuration on my end since...forever. Is anyone else seeing this, and why is the QID looking for what I assume to be eq 1 as opposed to gte 1.

Correct Answer

This post has branched out to include a several QIDs now, it started with two (2) and now includes five (5): 90559, 90560, 90561, 91263, 91449.

Are 90559 and 90560 were updated 06/24/2018. Are they still reporting so prevalently?

The changelog has not yet loaded on all platforms, but the QID detection signature was modified in an effort to minimize false positives.

This vuln was created 05/08/2018 and has not been modified since it was added.

Thank you for providing the QIDs. I have reviewed these QIDs in Vulnerability Signature Version:2.4.343-2 and noted that neither detection has been modified recently, and both require authentication for accurate detection.

Have you validated your scan authentication is completing successfully?

Charles, I concur with the earlier recommendation from Debra. Verify that the scan you performed was authenticated and also verify that auth was successful.

Report > Reports > New > Authentication Report

If auth was successful, Support will have to investigate this. Please open a ticket.

  Authentication is not the issue. As I mentioned in my original post, these are Agent-based results and not from scans. We have not performed scans on workstations since they first had Agents installed, well over a year ago. Detections on these QIDs are new as of about a week or so ago. I've never seen them before in our environment.
  
  The agents are successfully reporting in, and the "Last Reported" timestamp reflect this, with it now showing 4:45 a.m. today with the same results. That result shows Qualys seeing SP 2 is installed, but that doesn't seem to satisfy the test for SP 1.
  
  RESULTS: HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v2.0.50727 SP = 2
  
  I will open a support ticket.

Charles, we're also seeing this and seeing some other QIDs that seem wrong as well that came up around the same time. Please post up if support is able to help.

Hi all,

We have noticed the same situation and opened a support case (will post response if I get one before this thread is resolved).

I found that these .NET SP vulns started popping up after we patched for QID 91449 Microsoft .NET Framework Security Update May 2018.

  Hi all,
  
  I received a response from support indicating the .NET SP vulns that popped up after applying the .NET May patch are indeed false positives - response posted below:
  
  Hello Brett,
  
  I am (support rep) from Qualys Support and I was going through this case. I see that QIDs 90559, 90560, 90561 are getting flagged on the agents even though higher patches are already installed.
  
  This is a genuine Agent FP and our teams are already working on this issue.
  I will let you know once we have a confirmation on the fix version.
  
  I will continue to post any updates I receive here - thanks!

I too have the same issue. with these QIDs popping up for every machine. Despite not even having .net 2.0 or 3.0 installed on any of them! How can I install a service pack for software I don't even have? Obviously it's a false positive.
I have a sneaky suspicion this is causing other QIDs to pop up as well as a result.
Such as 91263.
91263 - Microsoft Graphics Component Remote Code Execution Vulnerabilities (MS16-097) now on all my machines, when I try to install the relevant patches as per Qualys' advice, I'm told by my server that 'the update is not applicable'. Anyone else get this too? There are also no results available to any of the instances that apparently have the vulnerability...

  Hi Antoin,
  
  I noticed the presence of MS16-097 as well. The same not applicable situation and nothing detected in the results field - I've got a case open regarding it and will post the result once I have a response.

  Hi Daniel,
  
  Thank you for sharing the Scan Reports.
  
  We have already notified our internal engineering team on this as there are multiple customers who reported the similar incident.
  I'll get back to you with an update shortly.

  For those of you concerned about these QIDs reporting within your environment, I recommend proceeding with a targeted rescan of Q90559 and Q90560, on only those assets that were previously reporting. To create a concise scan list of assets currently reporting the previously noted QIDs:
  
  Via AssetView, use query: vulnerabilities.vulnerability:((qid:90559 or qid:90560) and (not status: fixed)) and vulnerabilities.lastFound < now
  
  Via Asset Search, and you can create and create a new tag or asset group or launch your scan using a custom search list:
  
  Also, if you are participating in the Dashboard Toolbox - New Vulnerability Management (VM) Dashboard BETA , I have attached a zip file containing a dashboard focusing on these specific QIDs and their status:
  
  dashboard_toolbox
  dashboard_ideation
  vmdb_beta

  I confirmed that I still have a large presence of QIDs 90559, 90560, 90561, 91263 on agent tracked hosts - most of which have last detected / check-in dates of early this morning (6/26).

      My host counts on these QIDs have started to drop slowly just since this morning - I will continue to monitor as agents check-in again and update.

      If the numbers stop dropping and level off, then would be the time to create a case for your false positive findings. I can assist if you need me.

        My detections have dropped to the expected levels now.
        so, no more false positives.

I received this update to my ticket regarding QID 91263, I assume they're going to be updating their detection relevance.

Hi Daniel,

I hope you are doing good and really appreciate your patience on this.

The engineering team has identified the fix for this issue , which will be implemented in next release in coming days.
At this moment , there's no action required from your end.

We'll get back to you with next update shortly once the fix is implemented from our end

Thank you,

  Tony,
  How closely are you connected with your windows engineering team? The fact that these older QIDs keep popping up in "waves" suggests the asset deployment may be being performed from an image that requires update. I would reach out to your IT team and check for a business process that is negatively impacting your VM process.

    Hi Debra, turns out that KB4525243 last month has superseded KB3178034 which is what the QID looks for. I wonder if the later KB has wiped out the expected reg setting?
    HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages\Package_for_KB3178034~31bf3856ad364e35~amd64~~6.3.1.0 is missing
