  • Windows Update breaks multipart/form-data

    Dec 09, 2015 01:22 AM|guerchmann|LINK

    Running Windows Server 2012 here, Classic ASP application.

    We have an image upload page which has been working for the last... ten years.

    <form method="post" enctype="multipart/form-data" action="...">

    Anyway, Windows Update ran today at about 10:30am NZ time. Afterwards users complained they couldn't upload images anymore. No error generated in logs. 

    Restarted pool, IIS, server - in that order. Nothing fixed it. Uninstalled today's Windows Update, restarted server, everything working again. 

    The updates offered are:

    • KB3104002
    • KB3119147
    • KB3099863
    • KB3108347
    • KB3108381
    • KB3109094
    • KB3109103
    • KB3102429
    • KB3112148

    Is there any way to find out which update broke this application?

    Cheers

    Yes, here too :-(

    The conflicting update is: 

    • KB3104002

    It updates the VBScript.dll and JSCript.dll that are part of Classic ASP.

    I'll try to report this to Microsoft and please do the same if you can.

    Same Here,

    After the updates our application is broken. Also, we cannot remove the update KB3104002. (Other updates of today are successfully removed) So the application is still broken. Will there be a patch soon?

    Any suggestions?

    Same thing happened to me, all sites on an updated server stopped allowing files to be uploaded.

    Managed to uninstall KB3104002, restarted and they are all working again.

    Hope Microsoft release a fix for this asap.

    The cause of the problem has been identified and we are currently working on a fix. This will eventually cover all affected platforms, but to help us prioritize, what OS are folks running that are directly affected by this? I saw Server 2012 mentioned above - anyone running anything else blocked by this?

    This was causing a major issue on our ecommerce site.  We were unable to get orders all day.  Our webhost was able to roll back the update today, but indicated that it could reinstall next Tuesday when Microsoft sends out updates again.  Very hopeful that Microsoft can resolve this.  I believe we are also on Server 2012.

    You know if you have this bug because the binary data of the multiform request will be corrupt. Rolling back the update solved the problem for us too. Or you can switch to an ASP.NET page just to handle the file upload request. Lots of happy customers called our support line today.

    Just chiming in to say we're having the same problem here. Rolling back the update on 12/9 fixed it, and this morning 12/10 the problem is back.

    I'll be checking in on this thread to see if/when there is a solution or a patch.

    I'm glad I stumbled on this thread; I would've been chasing my tail all day otherwise.

    Our upload for documents is broken also.

    We are using freeASPUpload.asp.

    The problem ist the VBScript function instrb() searching for binary arrays with the length of 1.

    instrb() workes correctly for me when searching for a binary array with the length bigger than 1.

    I reported this yesterday (probably at the wrong spot but I didn't know where else to report)

    https://connect.microsoft.com/IE/feedback/details/2110858/ms15-124-breaks-vbscripts-instrb-function-when-working-with-a-byte-safearray

    There is a test case and more details on the specifics there.

    We're running on 2008 R2 and 2008 here. There are a lot of older applications out there that still use classic ASP for file uploads, and they all broke all at once. It was kind of a support nightmare yesterday.

    Yes here too -

    Assumption, but it appears only FreeASPUpload and Pure ASP File Upload are affected by this. We've always recommended our customers to use Persits ASPUpload, which still works great. Maybe because it's a COM and not "pure ASP". Tested on Windows Server 2012 R2 IIS 8.5.

    It appears that the update is to the exe that processes vbscript - so it wouldn't surprise me if a com object continued to work fine.

    I hope MS can fix this one promptly. We can control the windows updates on our own servers, but many of our clients run our software on shared hosts or machines elsewhere.

    It's back!  My machine decided to re-install the security update again last night and it broke my ASP page file uploading.

    https://support.microsoft.com/en-us/kb/3104002

    I see that in this article MS admits it causes ASP pages to fail. It doesn't seem to say when that issue will be fixed.  I hope MS is fixing this immediately as all of my clients file upload feature of my ticketing software that I sell is broken until they un-install that security update.  I sent an email to all of my users to go to windows update yesterday and un-install the this security update.  If anybody has information to when MS will send out a new patch with corrects to their VB language errors please post it here.

    It seems like this update has actually broken ASP VB script so you might have other ASP problems too much more than file upload if you happen to use this particular VB script function.

    Here is more about the issue:

    A bit of extra detail: Update KB3104002 is the one to remove on Windows 2008r2 also.

    As well as the problem (with instrb and related functions?) which for one thing breaks upload handling functions/components, we found it created "random" corruption of the output of a couple of scripts that did not use these functions. Removing this update seems to have corrected this problem as well as the one already discussed above.

    The corruption was in the form of space delimited sequences of 8-bit values in hexadecimal inserted into the output, always I think at points were a server-side code block started. The added data was not entirely random - near the top of the page the same values were inserted in much the same places (even after the output started to vary due to differences in request parameters and database contents from call-to-call) and once the added text did start to vary it was the same for each version of the output (where the output version is determined by data read and output in response to query string inputs). Just to make it more interesting: there are a significant number of scripts in the app in question that were completely unaffected, and the affected script was not always problematical: after an IIS reset all was well for a while (up to a couple of hours, though sometimes only minutes - I was unable to find a pattern to explain what was tripping the change in behaviour) before the aberrant behaviour returned.

    I have sample clean and corrupted output data if there is somewhere official it would be useful to submit that too. The script in question is likely too large to be useful as an example to replicate the problem, but if it would help MS's diagnostics I could hack it down to try create a minimal affected script.

    OK Scott, we are having almost close match same problems, I am looking for help to fix.  My wife and I have matching computers, both have Windows 10, both have Internet Explorer 11.  Both of them auto downloaded and installed updates, patches, fixes, etc. (as if we can stop it) from Nov. and Dec. 2015.  No problems before... but now, we click on IE and nothing, we click on Edge and nothing, we go to Control Panel and click on Internet Options, and nothing.  We can click on Google Chrome (what I am using right now) and AOL.  The IE desktop icon used to say "Internet Explorer", mine now has nothing under it, wifes has "%nternet Explore%" under hers.  I have been searching and searching for a fix, repair, ... anything to fix and to understand what is happening.  So far your posting is the first one I have come accross, after I came accross "Security Bulletin MS15-124" and started searching using it.  MS, Forum users, anyone...

    Same issues here. on my VPS i managed to removed KB3104002, which then re-installed itself. uninstalled it again, and change the update settings... hopefully it will ask next time.

    But i have many sites on shared hosts, and the issue exists there as well - they will only agree to uninstall it for up to 45 days and then they say they must re-apply the KB, because of security holes.

    I hope MS can come up with a fix by then...

    I was able to fix this on my Windows servers by installing PHP and using the script shown here: http://www.w3schools.com/php/php_file_upload.asp

    You will need to adjust the the file size limit see: http://stackoverflow.com/questions/2184513/php-change-the-maximum-upload-file-size

    Doesn't take long to install PHP - use Windows Platform Installer if possible.

  • Re: Windows Update breaks multipart/form-data

    Installing PHP is not an option for everyone - it adds complexity to environments including patching, maintenance, more processes on the platform, memory requirements, completely new platform to manage, etc. This costs time and money and should only be considered as last resort and part of a well thought out strategy.

    An update on the fixes: we're working as fast as we can on getting the fixes out. There is quite a matrix of platforms depending on OS and IE version, so we're prioritizing fixes for the common Server platforms (ie those impacted in production) first. We hope to have these available as early as mid this week.

    If anyone cannot wait for the official fixes and requires more urgent assistance (e.g. blocked in production) then please contact Microsoft Support for assistance (http://support.microsoft.com/oas , enter ‘Microsoft Internet Information Services X.X’ based on the IIS version, set Problem Type='Active Server' and for Category='Script engines and languages')

    We have official fixes available now!! https://support.microsoft.com/en-us/kb/3125446

    You will need to click on the 'Hotfix Download Available link', select the appropriate OS then enter email address. You will then get an email with a direct link to the hotfix installer.

    Hotfixes available:

    - Win8.1/Win2012 R2 (IE11)
    - Win8/Win2012 (IE10)
    - Win7/Win2008 R2 (IE11, IE8)
    - Vista/Win2008 with IE8
    - Vista/Win2008 SP2

    Mini FAQ:

    "When will fixes be on Windows Update?" - The hotfixes in the link above need to be manually installed. Automatic patching via Windows Update will be available approx. mid Jan 2016.

    "What if my configuration is different from what's available via Hotfixes?" - The hotfixes are meant to unblock customers running on the most common server platforms. There is a large matrix of potential configurations depending on OS and IE versions. The Jan updates from Windows Update will cover a much wider range of configurations than what the hotfixes target. If you're still blocked, cannot wait until the January updates and the hotfixes doesn't address your configuration then please contact Microsoft support for assistance (see my post above for more details).

  • Re: Windows Update breaks multipart/form-data

    Dec 17, 2015 09:01 PM|davidso|LINK

    Still working on getting 2012 hotfix out but hopefully very soon....

    The hotfix targets vbscript.dll whereas the update (KB3104002 - the one that initiated this whole post) has much more content than that. So the hotfix is not a replacement for the update.

    According to https://support.microsoft.com/en-us/kb/3125446 having KB3104002 is a prerequisite, which means you're supposed to install the hotfix on top of KB3104002 on your machine. This will result in all the IE security fixes from KB3104002 as well as the patched vbscript.dll.

    Not sure if it's an officially supported sequence though I was able to have the following work: machine without KB3104002 (e.g. was manually uninstalled at some point due to breaking impact)-> install hotfix 3125446 -> run windows update (brings back KB3104002) -> install update KB3104002.  I successfully tried this with the 2012R2 hotfix and it likely works due to the fact that the file version of vbscript.dll in the hotfix has higher number than that in the KB3104002. However if you run into any problems then go with the official way (update KB3104002  then hotfix KB3125446)

    HTH.

    By the way: after having installed the private hotfix, since it's not an officially  supported one, you'll get a "For testing purposes only" message in your desktop.

    This is a normal situation:

    However: Is this going to dissappear when the official path is released?

    additional fixes for Server 2008 and 2012 are now available! The KB text at https://support.microsoft.com/en-us/kb/3125446 hasn't been updated yet, but if you click on 'hotfix download available' link then you'll see 2 new options:

    -Windows 8/Windows Server 2012 RTM
    -Internet Explorer 8 for Vista and Server 2008 (in addition to 'Windows Vista/Windows Server 2008 SP2')

    48891_intl_x64.zip is for 2012R2 only. You'll need to install the one for 2012 (489064) that just got released.

    Re JM Alarcon:

    The 'for testing purpose' message will go away after you uninstall the private hotfix (KB9999999). You will need to uninstall the private hotfix and then install the official one.

    re mathewspv: you have to select the hotfix you want (e.g. 'Windows 8/Windows Server 2012 RTM' for 2012) then enter your email address. You will then get an email with the direct link to the download. For hotfixes we do it this way just in case we later find problems with the hotfix and need to contact our customers.

    I filled the form with my email (tryed with a alternative mail too) and i did n´t received the email from microsoft with the link in both of them.

    So my team had to rewrite the upload scripts using persists upload. (We delayed our current project)
    Now upload feature works again.

    If i was wait for the fix would be on big trouble considering the importancy of the upload feature.

    Good day,

    I have this problem with Windows 10 upgrade (kb3116900), and now (kb3121200).
    that solution?

    My websites are hosted by Godaddy on their Windows Server and I have been having this problem for the past two weeks.

    I have informed them of the problem but they are in denial that the problem exist.

    I have even sent them the link with hotfix but haven't received any notification from them that they are looking into the problem.

    Is is possible for someone from Microsoft to contact them, informing them that this is in fact a real problem and that the patch needs to be applied.

    This is a tall order but what else can I do.

    L.S.,

    We have Windows 2008 R2 32bit with IE9. None of the (new) updates seem to work. Has this configuration been addressed too?

    Message is: 'The update does not apply to your system'.

    Re Doomie1982:

    As I mentioned in an earlier post, the hotfixes are meant to unblock customers on the most common platforms and not meant to address all possible combinations of OS and vbscript/IE versions. The Jan round of updates will cover wider range of combinations than what the hotfixes will cover. For Win2008 R2 x86 there are fixes available for IE11 and IE8. So you can either downgrade (on the server) to IE8 and install the 'Windows 7/Windows Server2008 R2 SP1' hotfix, or you can upgrade to IE11 (on the server) to IE11 and install the 'Internet Explorer 11 for Windows 7/Windows Server 2008 R2 SP1' hotfix.

    I want to give a shout out to Matt3k who was on top of this on other sites.  I got hit with this on Sunday the 20th (I was behind with windows updates), and it came as quite a shock.

    The removal of the KB as well as patching with the hotfix did not resolve the issue, however, code provided to sidestep instrb worked like a charm.

    Said code (from him) is:

    Function InstrBNew(startPos, inputArray, searchChar)
    
      if LenB(searchChar) = 1 Then
        Dim loc
        For loc = startPos to Lenb(inputArray)
          if MidB(inputArray, loc, 1) = searchChar then Exit For
        Next
        InstrBNew = loc
      Else
        InstrBNew = InstrB(startPos, inputArray, searchChar)
      End If
    End Function

    I added that to my upload.asp file and called the function in place of instrb, worked like a charm.

    Happy users = happy life!

    Ok, so backed out too, didn't work. Tried code changes from InstrB to InstrBNew and didn't work, other bugs.  Then read through this ...

    http://stackoverflow.com/questions/34181411/uploading-a-file-in-classic-asp/34188295#34188295

    ... and decided to just change CByteString(Chr(13)) to Chrb(13) where it was used, and PRESTO, all working again.

    Having the same trouble with Windows 10 Pro 64bit, production environment.  Had tracked down the problem to instrb( then found this forum.  Anyone have any idea which KB# update needs to be uninstalled in Windows 10 to resolve this?  Or, preferably, when the hotfix will be available for Win 10 64?

    Hello David

    We are having the same issue on Windows 7 Enterprise SP1 64bits / Internet Explorer 10.

    Will you provide a hotfix for that Platform?

    Re Win10: this will be addressed by a Jan set of updates (hopefully in just over a weeks time).

    Re Win7 IE10: There is a hotfix available for Win7 IE11, so you can upgrade from IE10 to IE11 then apply that hotfix. If that's not an option then you could wait for the same set of Jan updates that I mentioned above.

    Hi folks... I haven't applied the fix on our Windows Server 2012 boxes because I still have a question - shall I apply the original patch then the fix, or just the fix?

    My webhost server told me to install MS Hotfix to fix security update 3104002 to my own computer, is that true or they need to install the hotfix to the host server themselves?  thanks!

    re: guerchmann - I think I answered this above https://forums.iis.net/post/2114334.aspx

    Assuming by original patch you mean KB3104002 then both should work and get you to the desired state (updated vbscript.dll). If you're referring to the private hotfix (KB9999999) then that does need to be removed first.

    Re Patrick H: the hotfix needs to be installed on the machine that is running IIS. So if you're using a webhost company to host IIS then installing the hotfix on your own (client) machine would have no impact whatsoever.

    Do we have a date for when the new January updates will resolve this issue and we don't have to either continually uninstall or apply the patch?  I have several clients of my help desk product who I would like to inform them of an update that should resolve this issue.

    We have a server running Windows Server 2008 SP2 suffering from this issue.

    I have downloaded the hotfix for Windows Server 2008 SP2 x86 but when running I am told 'The update does not apply to your system'.

    We're running IIS 7.0 and IE 9, but the IE on the server is not used at all for anything.

    Any reason this hotfix doesnt not work on our server? Does IE 9 need to be downgraded to IE 8? I saw a similar post above from someone trying to fix their 2008 R2, but the original post regarding the hot fixes specified IE 8 for 2008 R2 but no IE was specified for 2008 SP2

    re: 4fxdev The hotfix for 2008 SP2 x86 is for IE7. In your case you may want to downgrade to IE8, install security updates for IE8 and then the hotfix for Win2008 with IE8. Or wait for the January updates.

    Can you confirm that the windows update last night has fixed the original ASP download problem created by KB3104002 and folks do not need to apply any hot fixes or un-installed KB3104002 any more?  I want to send a note out to my clients that this issue should have been addressed by the updates distributed on 1/12/2016.  Thanks

  • Re: Windows Update breaks multipart/form-data

    Jan 13, 2016 07:59 PM|davidso|LINK

    Correct. Last nights Critical Security Update (https://technet.microsoft.com/library/security/MS16-001) fixes the 'original ASP issue caused by KB3104002' and also includes additional security updates.

    So the simplest answer is just move to the latest updates.

    If you have the hotfix (kb3125446) installed already you don't need to worry about uninstalling it as you can install MS16-001 on top (as it has a newer version of vbscript.dll than the hotfix).
