vSphere UI must limit the maximum size of a POST request.

An XCCDF Rule

Description

The "maxPostSize" value is the maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. Limit its size to reduce exposure to a denial-of-service attack. If "maxPostSize" is not set, the default value of 2097152 (2MB) is used. The vSphere UI is configured in its shipping state to not set a value for "maxPostSize".
