How to solve eMAM Panel loading problem after latest Microsoft security patches

Microsoft released a security update which is having changes in the cookie handling. Please refer this article for more details - https://devblogs.microsoft.com/dotnet/net-framework-december-2019-security-and-quality-rollup/


This will affect the applications which are loaded inside an iFrame. eMAM panels are following this architecture so it will be an issue for now. Our engineering team started working on this to fix this issue from the code level

but Adobe also needs to update their Chromium version in order to support this in eMAM Panels. We found some workarounds to tackle this issue until Adobe releases that update. Please follow the below steps.


1. We will be tackling this issue by configuring a URL re-write in IIS level.

2. Download and install URL rewrite module in eMAM Web servers. If there are multiple web servers, then install it in all the Web servers. Download link - https://www.microsoft.com/en-in/download/details.aspx?id=7435

3. After installing the URL rewrite module, please go to C:\Program Files\Empress Media\eMAM Director in eMAM Web server and open web.config.

4. Search for <System.webServer> and paste the below content under that tag. Please find below.

<rewrite>

    <outboundRules>

       <rule name="Remove SameSite">

             <match serverVariable="RESPONSE_Set_Cookie" pattern="(.*;) SameSite=(strict|lux)*" />

              <action type="Rewrite" value="{R:1}" />

       </rule>

    </outboundRules>

</rewrite>

5. After adding this configuration, please open Premiere panel or other eMAM panels and check whether it fixed the issue.
