The Cisco guidance mentions that access lists are probably effective:

https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-webui-privesc-j22SaA4z

"We assess with high confidence, based on further understanding of the exploit, 
that access lists applied to the HTTP Server feature to restrict access from 
untrusted hosts and networks are an effective mitigation."

Is there a better way of restricting access to management interfaces of a L3 
switch say to certain VRFs or interfaces?

All the best

David
