Information

The secure flag is an option that can be set by the application server when sending a new cookie to the user within an HTTP Response. The purpose of the secure flag is to prevent cookies from being observed by unauthorized parties due to the transmission of a cookie in clear text. By setting the secure flag, the browser will prevent the transmission of a cookie over an unencrypted channel. The ESX Agent Manager is configured to only be accessible over a TLS tunnel, but this cookie flag is still a recommended best practice.

Solution

Navigate to and open:

/usr/lib/vmware-eam/web/webapps/eam/WEB-INF/web.xml

Navigate to the /<web-apps>/<session-config>/<cookie-config> node and configure it as follows:

 <cookie-config>
 <http-only>true</http-only>
 <secure>true</secure>
 </cookie-config>
