details and proof-of-concept (POC) for a \"0day\" local privilege escalation vulnerability in Windows Task Scheduler service, allowing a local unprivileged user to change permissions of any file on the system. The next day, we at 0patch have analyzed the vulnerability and prepared a \"micropatch candidate\" (a micropatch that blocks the POC but needs to be tested for functional side effects). We published the micropatch for Windows 10 version 1803 the day after, and subsequently ported this micropatch to a number of other Windows versions.\n\nObviously, correcting someone else's code is not to be taken lightly (especially if that code is running on millions of computers), and not having the source code doesn't make it any easier. However, our team of security researchers and the growing community of experts who want to get their vulnerabilities fixed as quickly and efficiently as possible, are doing just that.\n\nIn this particular case, our analysis showed that a call for changing permissions of a file, made from Task Scheduler's code, should have been impersonated - but it wasn't. We corrected that by making a call to RpcImpersonateClient right before the call, and another call to RpcRevertToSelf right after it. Pretty basic stuff. And it worked.\n\nOur micropatches are sometimes very similar to official patches (at least functionally speaking), and other times very different; not surprisingly, there is always more than one way to skin a cat - or to fix a vulnerability. So when the official patch from Microsoft came out today, we were naturally curious as to how they fixed it.\n\nThe first thing we noticed was that the Windows Update replaced schedsvc.dll with a new version. Promising - this is the exact DLL we had micropatched. Next we ran BinDiff to compare the new and the old version. Even more promising - the only modified function was RpcServer::SetSecurity, which is the very function we had micropatched. And finally, BinDiff showed the exact difference between the old and the new version of this function. Let's take a look at that (note: the diff is for 64bit Windows 7).\n\n",{"item":793,"type":840},"block",{"type":814,"children":842},[843],{"type":817,"value":844},"\n\n \nAs you can see, Microsoft's official patch is functionally identical to our micropatch. We could say that this official patch delivers Microsoft's unofficial confirmation that our approach to patching this vulnerability - in a complex closed-source product - was also optimal from their perspective. That's very positive feedback for us and a great case for \"unofficial\" 3rd-party micropatches.\n\nDon't get carried away, however! There have been, and will be cases where a 3rd-party micropatch will fix a vulnerability differently and less well than the official vendor fix - or even break a thing or two. While we're doing our best and leverage our advantages (agility, instant patch deployment, instant patch removal), original product developers will always have advantage in their knowledge about the product and its environment, and their code fixes will be preferred. Nevertheless, our mistakes are much easier to remedy than those delivered in a 300MB package that requires a reboot both to install and uninstall. When a micropatch needs to be revoked, it takes just a few minutes for us to do that, and within an hour all online agents stop applying it without interrupting users in the slightest. And an improved version of the micropatch can later be delivered just as easily.\n\nIn any case, if you have installed 0patch Agent to micropatch this vulnerability on your computer(s), it is now time to let the official fix take over. To do that, you simply apply today's Windows Updates and as soon as they replace the vulnerable schedsvc.dll, our micropatch will automatically stop applying because the cryptographic hash of the DLL will no longer match that associated with the micropatch. You don't have to do anything else; this is 0patch being a good citizen and stepping aside when it's no longer your best option.\n\n\nCheers!\n\n",{"type":814,"children":846},[847,854,856,862],{"url":848,"meta":849,"type":12,"children":851},"https://twitter.com/mkolsek",[850],{"id":823,"value":824},[852],{"type":817,"value":853},"@mkolsek",{"type":817,"value":855},"\n",{"url":699,"meta":857,"type":12,"children":859},[858],{"id":823,"value":824},[860],{"type":817,"value":861},"@0patch",{"type":817,"value":863},"\n\n\n\n\n",{"type":814,"children":865},[866],{"type":817,"value":40},{"alt":719,"url":797,"width":798,"height":799,"responsiveImage":868},{"srcSet":869,"webpSrcSet":870,"sizes":871,"src":872,"width":873,"height":874,"aspectRatio":875,"alt":719,"title":719,"bgColor":805,"base64":806},"https://www.datocms-assets.com/166020/1755778196-windows-7-official-patch.png?auto=compress&crop=focalpoint&dpr=0.25&fit=crop&w=1440 360w,https://www.datocms-assets.com/166020/1755778196-windows-7-official-patch.png?auto=compress&crop=focalpoint&fit=crop&w=1440 1440w","https://www.datocms-assets.com/166020/1755778196-windows-7-official-patch.png?auto=compress&crop=focalpoint&dpr=0.25&fit=crop&fm=webp&w=1440 360w,https://www.datocms-assets.com/166020/1755778196-windows-7-official-patch.png?auto=compress&crop=focalpoint&fit=crop&fm=webp&w=1440 1440w","(max-width: 1440px) 100vw, 1440px","https://www.datocms-assets.com/166020/1755778196-windows-7-official-patch.png?auto=compress&crop=focalpoint&fit=crop&w=1440",1440,1015,1.4187192118226601,1780067960612]
