VCUI-80-000152 - The vCenter UI service must enable "ENFORCE_ENCODING_IN_GET_WRITER".

Information

Some clients try to guess the character encoding of text media when the mandated default of ISO-8859-1 should be used. Some browsers will interpret as UTF-7 when the characters are safe for ISO-8859-1. This can create the potential for a XSS attack. To defend against this, enforce_encoding_in_get_writer must be set to true.

Solution

Navigate to and open:

/usr/lib/vmware-vsphere-ui/server/conf/catalina.properties

Update or remove the following line:

org.apache.catalina.connector.response.ENFORCE_ENCODING_IN_GET_WRITER=true

Restart the service with the following command:

# vmon-cli --restart vsphere-ui
