Afternoon,

 

Whilst not directly related to Veeam it’s worth reminding those of you using VMWare in your environments that if you’re using a version of vSphere that requires Flash, you have until the 12th January before Adobe trigger the kill switch preventing Flash from running, permanently. This could also cause you pains if you have plugins that either haven’t been upgraded to HTML5 yet or don’t have feature parity with their Flash counterparts.

 

If you’re not on a version of vSphere that supports HTML5 or you haven’t got all the Flash client features you’re either running an unsupported version or you’re extremely out of date on your patching and haven’t got full feature parity yet.

vSphere 6.7 is still carrying Flash too, though thankfully the main index page tries to steer you to HTML5 first!

Though Flash has ended its support, the ghost of flash will linger for long. Just like many obsolete technologies.

There will be hurdles and many major security risks along the way.

  • Adobe have removed all download links for Flash from its website, meaning anyone trying to install flash to a new machine that didn’t already receive an offline installer via Adobe’s mass deployment enablement programs will be forced to fetch from a third party site, running the risk of malware.
  • Adobe’s recent clients have a kill switch of 12th January 2021 whereby they’ll stop working unless you amend the configuration for specific sites to trust, but Adobe don’t provide information of this on the general EOL website so this might not be recognised as an option by some. @vNote42’s link he provided in this thread has some excellent information on configuring this, whilst the link is focused around VMWare, the advice could be applied to most.
  • People may cling to “old” clients without the kill switch, as Adobe have only released security updates for Flash over the last few years this means the old flash clients could easily be exploited.
  • The obvious, no new security patches will be released, hence credit to Adobe for actually stopping the execution of Flash without specific overrides, preventing drive-by style attacks.

It’s definitely aggressive but Adobe have never been one to shy away from controversy, look at their subscription only business model now, I’m still clinging to my old CS6 license even though it’s not officially supported on latest Windows 10 releases...

Yes, you have the choice between H5 and Flash Client in 6.7. But in later 6.7 versions everything can be done with H5 (with some limitations with Update Manager, form my perspective). So you do not need Flash in latest 6.7. Since 7.0, no Flash Client is available anymore.
