Chocolatey and TLS since early 2020

Posted by jpluimers on 2020/03/19

I was upgrading a few older systems that had been off-line for quite a while.

When installing Chocolatey, I bumped into this error:

C:\bin>"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"
Exception calling "DownloadString" with "1" argument(s): "The request was aborted: Could not create SSL/TLS secure channel."
At line:1 char:1

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : WebException

So I tried [WayBack] chocolatey “The request was aborted: Could not create SSL/TLS secure channel.” – Google Search

Results indicated TLS 1.1 support was removed early February 2020 from Chocolatey because of security reasons, which impacts the installation on older systems:

Note [WayBack] Chocolatey install Error: The request was aborted: Could not create SSL/TLS secure channel – Stack Overflow with a temporary workaround for Microsoft Windows Server 2016:

Looks like the security protocol changed:

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

When you cannot RDP to a target because of “CredSSP-encryption Oracle remediation”: apply your target security patches.

Posted by jpluimers on 2018/06/29

If you get the below error, then your RDP target server needs to be patched.

You can choose to stay vulnerable and modify your policy or registry settings as explained in the first linked article below: that is a temporary “workaround” which I do not recommend. Please update your RDP target servers in stead.

English:

[Window Title]
Remote Desktop Connection

[Content]
An authentication error has occurred.
The function requested is not supported

Remote computer: rdp.example.org
This could be due to CredSSP-encryption Oracle remediation.

[OK]
