Important update - Issue when using Windows 10 Creators Update (March 2017 Update, build 1703)
 
A problem has been identified within WebX clients after upgrading to the Windows 10 Creators update build 1703 whereby the scroll bars on an embedded list control (e.g. SQL Query, Event List, Alarm List on a mimic) in WebX no longer work as expected. We are actively working with Microsoft on this problem, which has been recently confirmed as an issue in MS Internet Explorer. MS Issue Reference: REG 117052415792436.

Current advice for ClearSCADA customers using WebX is that they should avoid upgrade of their Windows 10 clients to Creators Update build 1703 until this issue is resolved.

Customers impacted by the above are encouraged to raise this directly to Microsoft via their Support Channels, quoting the Issue Reference: REG 117072016066603, to help facilitate a timely resolution.

Recent testing has uncovered a potential work-around; when using Google Chrome browser and the IE Tab Extension (which simulates an Internet Explorer browser) version 10.7.31.1 we were able to successfully use the embedded mimic's scrollbars. The following considerations apply:

  • We have not formally tested WebX using Google Chrome’s IE Tab Extension.
  • Using Chrome web browser may be a problem for some customers (e.g. a Security Policy might exclude the use of Google Chrome browser, or the extension kits)
  • The extension may be using an older version of Windows library, and a newer version of the extension might reveal the problem again.

Thanks for your support, but overall we apologize for any inconvenience.

Microsoft provides the Windows Update Service that securely distributes updates and bug fixes in the form of patches. Microsoft schedules the release of patches via Windows Update every second Tuesday of each month, which has unofficially become known as 'Patch Tuesday'.

To provide customers the confidence that they can install Microsoft patches without adversely affecting existing installations of ClearSCADA, a set of regression tests are run on currently supported ClearSCADA versions and their supported server and workstation Microsoft Windows Operating System versions. These regression tests are run on the newly-released Windows patches monthly, with the results published on this page for reference once they are released.

The results documentation is cumulative, meaning that the results from the current month's testing are added to the results of the previous month, and so forth. As a result it is only necessary to review the current month's results spreadsheet to get a comprehensive understanding of the testing performed in the current calendar year. Testing results are archived annually, with previous years' results available below for reference.

Any testing is performed using all the approved previous months of patches installed, except where a more recent patch supersedes that earlier patch.

Any out-of-band (unscheduled) patch released by Microsoft is not tested until the next 'Patch Tuesday' scheduled patches are released, at which point the out-of-band patch will be tested alongside the scheduled patches.
Only Microsoft Windows Server, Workstation, .NET and Internet Explorer security and general updates are tested, any other Microsoft products such as Microsoft Office and Windows Defender are not included within the approval testing.

Third party patches such as those provided by SAP (Crystal Reports Editor), Oracle (Java) and Adobe (Reader) are not included within the testing.

Adoption of Rollup Updates

From October 2016, ClearSCADA has adopted Microsoft's new 'Rollup updates' for patch management, which is a single package containing all Security and Operating System updates for the month. This monthly package is also cumulative, combining new monthly patches together with existing ones so there only a single package to apply to your Operating System.

As part of our monthly Microsoft patch testing activities, the ClearSCADA team will verify that all updates included within the monthly package are compatible with supported versions of ClearSCADA and Windows Operating Systems. Our Microsoft Update report will be updated accordingly to reflect this change, and will include a link to the Microsoft website containing details of the individual updates.

If for any reason the update is unsuccessful, the testing will be limited only to the security updates for that month, which if successful will be published to provide you the confidence to install the security update package. In the event of either updates being unsuccessful, investigation will be undertaken by the ClearSCADA team to diagnose and rectify associated problems as a matter of urgency.

If you have any questions or concerns regarding this change in process, please don't hesitate to contact your local Technical Support team.

Microsoft Update Testing

It is anticipated that the results of the next round of Microsoft patch testing will be published here by October 25th 2017

There was no update testing performed in February 2017 as Microsoft chose to not release the scheduled patches until March due to undisclosed problems: https://blogs.technet.microsoft.com/msrc/2017/02/14/february-2017-security-update-release/

Schneider Electric recommends that this released patch information is used alongside a suitable patch management process, for example as documented in IEC-62443-2-3, which includes additional local testing using customer specific configuration prior to deployment to any production system
